From 791da7b34588c28e332db7099102008c695324cc Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 6 Jul 2026 06:13:18 +0000 Subject: [PATCH 001/108] feat(editor): zoom-aware page-fit + metadata label stacking (4a.4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement two Phase 4 / 4a.4 (Spec 03) responsive sub-items from the deferred-features plan: Real Viewport.zoom — the status-bar zoom now drives the shared responsive Viewport::zoom. `editor_responsive` gains pure `zoom_fraction` / `desired_view_mode` helpers wired into the page-fit effect and the context-publish effect, so zooming a page past the point a full column fits the viewport flips the editor into the reflow renderer (and back on zoom-out) instead of forcing horizontal scroll. Hit-testing uses a separate local Viewport and is unaffected. 5 regression tests. Metadata-panel label stacking (R-13g) — FieldRow becomes a #[component] that reads use_viewport() per ADR-0013; below 250 px the field label stacks above its input (flex column) so the input keeps a usable width on narrow/split-screen viewports. Pure `stack_labels` helper + 3 tests. Docs: plan 4a.4 rows and fidelity-status reflow row updated. editor_inner.rs kept net-neutral against the file-ceiling ratchet.

The format-neutral model stores math as a single MathML `` string in `Inline::Math` (the W3C interchange standard and ODF's native form). **DOCX** converts bidirectionally between OMML (`m:oMath` inline / `m:oMathPara` display) and MathML in `loki-ooxml`'s `docx/omml` module; the converter is mutually inverse over the common construct set — text runs (`m:r`/`m:t` ⇄ ``/``/``), fractions (`m:f`), super/subscripts (`m:sSup`/`m:sSub`/`m:sSubSup`), and radicals (`m:rad` ⇄ ``/``). **ODT** embeds the MathML as a formula sub-document (`draw:frame`/`draw:object` → `Object N/content.xml`, listed in the manifest with the `…opendocument.formula` media type) and reads it back, canonicalising on import (`loki-odf`'s `odt::math`); ODF does not distinguish display from inline math, so embedded formulas map to `MathType::InlineMath`. **Persisted through the Loro CRDT** losslessly: a block containing math is preserved as an opaque snapshot. **Rendered** by a first-pass math typesetter (`loki-layout`'s `math` module): the MathML is laid out into positioned glyph runs (tokens shaped via Parley) plus fraction-bar/radical rules, then placed inline via a Parley inline box (the same mechanism as tab stops). Covers identifiers/numbers/operators, rows, fractions (`mfrac`), scripts (`msup`/`msub`/`msubsup`), radicals (`msqrt`/`mroot`), and fenced expressions (`mfenced` / fence-wrapped rows) — reusing the standard `PositionedItem` glyph/rect types so `loki-vello` paints it with no renderer change. **The equation's baseline is aligned to the text baseline** (the inline box reserves the equation's ascent; Parley aligns box bottoms to the baseline, so the descent hangs below into the line like inline text, and the paragraph height grows to cover a deep denominator). **Radical signs and delimiters stretch to their content** via uniform glyph scaling. **Math is set in a serif/math face** (`FontFamily::Source("Cambria Math, STIX Two Math, Latin Modern Math, serif")` in the token shaper) rather than the sans-serif body default, matching Word's Cambria Math. **A paragraph that is solely an equation is centered** (display math): Word renders both `m:oMathPara` and a bare paragraph-level `m:oMath` as a centered display equation, so the DOCX mapper centers a paragraph whose only content (ignoring whitespace) is math when it has no explicit alignment. Tested by `omml_tests` + `math_round_trip.rs` (DOCX), `math_tests` + `math_round_trip.rs` (ODT), the `math::tests` typesetter unit tests (incl. stretch), and `inline_math_emits_typeset_items` / `inline_math_baseline_aligns_with_text` (layout integration). **Approximations / not yet done:** stretchy glyphs widen as they grow (uniform scaling, not true extensible glyphs); inter-atom spacing follows simple proportional gaps rather than the full TeX `mathspacing` table; matrices/n-ary operators/accents are not laid out. The OMML↔MathML converter likewise does not yet cover delimiters, n-ary operators, matrices, or accents (these pass through best-effort), so delimiter rendering currently applies to MathML that already contains fences (e.g. ODT-imported or hand-authored), not DOCX OMML round-trips. | | **Templates (DOTX / OTT)** | Yes | — | Partial | Office `.dotx`/`.dotm` and LibreOffice `.ott` open as new untitled documents (the importers key off the `officeDocument` relationship / accepted template mimetype). Export: **Save as Template** writes `.dotx` (template content type) via `DocxTemplateExport`. Five templates (Markdown, APA, MLA, Screenplay, Resume) ship as bundled `.dotx` assets (`loki-templates`) and open from the home gallery. | | **ODT export** | Yes | — | Yes | `loki-odf`'s `OdtExport` writes a full ODT package (`content.xml` / `styles.xml` / `meta.xml` + `Pictures/`). **Lossless** for: the complete character-property set (fonts incl. complex/East-Asian, size, weight, italic, underline, strike, caps, outline, shadow, super/sub, colour, letter/word spacing, kerning, scale, languages), the complete paragraph-property set (alignment, indents, spacing, line height, keep/widow/orphan/break flags, borders, padding, tab stops, bidi, background), the named style catalog, **multi-section page geometry** (each section gets its own `style:page-layout` + `style:master-page`; section breaks are emitted as `style:master-page-name` on the first paragraph of each section, the form the importer reads back), **headers/footers** (default/first/even, written per-section into the master page with their own automatic styles + images), headings, styled paragraphs, lists, tables, footnotes/endnotes, links, **bookmarks, fields, and embedded images** (decoded from data URIs and written as `Pictures/` parts), and core Dublin Core metadata. A property-level round-trip test asserts each survives. Editing an opened `.odt` and saving round-trips to ODT. **Multi-column sections** (`style:columns` with count/gap/separator), **extended Dublin Core** (publisher, contributors, rights, license, identifier, type, format, source, relation, coverage, issued, citation — carried as `meta:user-defined` entries under reserved `dcmi:` names), and **comments** (`office:annotation` / `office:annotation-end`) also round-trip. **Math** is emitted as embedded formula objects (`draw:object` → `Object N/content.xml` MathML, listed in the manifest).

Relayouts to the window width on resize (shell re-emits `onscroll` for scroll containers). **Bounded reading measure (Spec 03 M4):** the reflow tile is capped at `MAX_REFLOW_TILE_PX` (820 CSS px) and centred (`margin: auto`) on wide windows, so the line length stays comfortable instead of running edge-to-edge; narrow screens still use their full width. A single `render_layout::{reflow_tile_width_px, reflow_content_width_pt}` feeds paint, hit-test, and keyboard nav so they stay aligned (the HTML fallback references the same constant). Content wider than the viewport (e.g. a fixed-width table) widens the tiles so it is reachable by horizontal scrolling rather than clipped. No headers/footers/page chrome by design; the status-bar page indicator is hidden in reflow. **Editing:** `ContinuousLayout` carries per-paragraph editing data, so click-to-cursor, caret placement/painting, range-selection highlighting (mouse drag-select + Shift+Arrow), and reflow-native arrow / Home / End navigation all work, plus typing/undo/formatting. Selection editing is view-independent and works here too: typing replaces the active selection and Backspace/Delete remove it, incl. multi-block ranges (`delete_selection_at` + `editor_keydown_text.rs`, 2026-07-05).

It now lands in the first cell automatically (Word behaviour). - `insert_table_after_cursor` returns the first-cell caret via the new `first_cell_caret` helper (flat cell 0 / block 0 — top-left, since a `Table::grid` has no head/foot), instead of a bare block index. - The Insert-tab `run_insert` gains an `InsertResult` enum carrying an optional caret target; after relayout it collapses the cursor there via `set_collapsed_cursor`, which re-derives the page from the fresh layout (plan 4b.1). Footnote insert leaves the caret at the anchor, matching Word. - Extracted the async Insert → Image flow into `editor_ribbon_insert_image.rs` so `editor_ribbon_insert.rs` stays under the 300-line ceiling. Tests: 3 new in editor_insert_tests.rs (first-cell caret shape, table lands at block 1 with an empty first cell, no-cursor no-op). Full loki-text suite green; fmt + clippy clean; file-ceiling gate passes.

Model (loki-doc-model): - `get_block_list_id` reads a block's direct `list_id` para-prop. - `clear_block_list` removes `list_id` + `list_level` from a block's para_props (a no-op when absent). Both top-level, section 0. Editor (loki-text): - `is_empty_list_item_exit` — a pure predicate: plain caret (no selection) on an empty, top-level list item. `handle_enter_key` calls it, then clears the list props, relays out, and keeps the caret in the now-plain paragraph (page re-derived per 4b.1) instead of splitting. Nested list items (table cell / note) keep the split — the block API is top-level only. Tests: 4 model tests (read/clear + round-trip + no-op) and 5 predicate tests (empty/non-empty/plain/selection/nested). Both crates' suites green (441 tests); fmt + clippy clean; file-ceiling gate passes.

Unit-tested (5) without a Dioxus runtime. - `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber Table contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves so the ribbon never shows an orphaned contextual selection. Pure `ribbon_tabs` tested (3). - Table tab action "Delete Table" removes the whole table block via a new `delete_block` model mutation, disabled when the table is the document's only block; the caret re-homes to the neighbouring block. `delete_block` tested (3, incl. cross-section + out-of-range). - New `LUCIDE_TRASH_2` icon + `ribbon-tab-table` / `ribbon-group-table` / `ribbon-table-delete-aria` strings. Ceiling: `delete_block`/`insert_block_after` moved into a new `loro_mutation/block_edit.rs` (block.rs was over 300); `editor_inner.rs` kept net-neutral by routing the wiring through `use_ribbon_tabs` and collapsing two single-expression ribbon closures. Both crates' suites green (481 tests); fmt + clippy clean; ceiling passes.

Model (loki-doc-model, `loro_mutation/table_ops.rs`): - `insert_table_row` / `delete_table_row` / `insert_table_column` / `delete_table_column`, plus `table_grid_dims`. - Each rewrites the serde skeleton *and* minimally patches the flat `KEY_TABLE_CELLS` movable list — surviving cells keep their live CRDT text (the list is patched, never rebuilt), and skeleton/cell order stay in sync. - Scoped to simple grids (one body, no head/foot, no row/col spans, uniform width); any other shape returns the new typed `MutationError::UnsupportedTableStructure`. Deletes refuse the last remaining row/column. - 12 round-trip tests (`tests/table_structural_ops.rs`) covering shape, text preservation, bounds, merged-cell rejection, and composed edits. Editor (loki-text): - `editor_ribbon_table_ops.rs`: `run_table_op` derives the target row/column from the caret's cell, applies the mutation, and re-homes the caret to its shifted cell via the pure, tested `caret_flat_after` (a structural edit changes the flat cell indexing the cursor stores). - Table tab gains four buttons; row/column deletes disable at 1 row/col, and all four disable on a non-simple-grid table (only Delete Table remains). 4 app-custom table-op glyph icons + i18n strings. Both crates' suites green; fmt + clippy clean; file-ceiling gate passes (`delete_table_*` etc. live in their own module).

Alignment was a gap: the model helpers existed but were unused and top-level only. Model (loki-doc-model, new `loro_mutation/align.rs`): - Path-aware `set_block_alignment_at` / `get_block_alignment_at` (plus the moved top-level `set_block_alignment` / `get_block_alignment`), so alignment works inside table cells and note bodies. - Type-aware: a plain `para` is upgraded to `styled_para` (a bare `para` drops props on read), `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attribute. 5 tests in `block_alignment.rs` cover top-level, cell (path-aware), heading, round-trips, and the invalid-path error. Editor (loki-text): - `editor_alignment.rs`: `current_alignment` / `apply_alignment` resolve the caret's paragraph(s) via `resolve_format_ranges` (same per-paragraph mapping the inline toggles use), so a multi-paragraph selection aligns uniformly. - The six inline-format buttons and the four alignment buttons live in the new `editor_ribbon_format.rs`; `write_tab_content` calls the two group builders, dropping `editor_ribbon.rs` from the 300-line ceiling to 225. Both crates' suites green (473); fmt + clippy clean; ceiling passes.

The current size is read from the selection's direct size mark, stepping from an 11pt default when a range has no explicit size. - Pure ladder stepping (`grow`/`shrink`) plus end-to-end mark tests (5): ladder edges, off-ladder snapping, apply-over-selection-only, and grow-then-shrink round trip. - `font_group` builder in `editor_ribbon_format.rs`; 2 app-custom "A±" glyph icons + i18n strings. Both crates' suites green (204); fmt + clippy clean; ceiling passes.

Apply/clear go through the path-aware `mark_text_at` + `resolve_format_ranges` path, so colour works in table cells and across a multi-paragraph selection; Automatic writes `Null` to drop the direct mark and revert to the style colour. - `editor_ribbon_color.rs`: `font_color_group` renders coloured-square swatches inside `AtRibbonIconButton` (which takes arbitrary children); the active swatch reflects the caret's direct colour. `RibbonEditCtx:: finish` is now `pub(super)` so the colour module shares the relayout/sync path. - 3 tests: apply-over-selection-only, Automatic-clears, and round-trip into `CharProps.color`. Verified the renderer paints `CharProps.color` (resolve → StyleProperty:: Brush), so the colour is visible, not just stored. Both crates' suites green (207); fmt + clippy clean; ceiling passes.

Model (loki-doc-model, new `loro_mutation/page.rs`): - `set_document_orientation(loro, landscape)` and `document_is_landscape`. The layout engine reads a section's effective `page_size` directly and treats orientation as a flag, so the toggle swaps width↔height on every section's page-size map (when it doesn't already match) and writes the orientation flag — idempotent. `apply_mutation_and_relayout` re-derives the geometry and updates `page_width_px`, so the document re-flows at the new size immediately. - 4 round-trip tests (`page_orientation.rs`): fresh doc is portrait, to-landscape swaps dims + sets the flag, toggle-back restores, and same-orientation is idempotent. Editor (loki-text): - `editor_ribbon_layout.rs`: `layout_tab_content` with Portrait/Landscape buttons (active state from `document_is_landscape`). - `ribbon_tabs` gains the Layout entry; `CONTEXTUAL_TAB_INDEX` 3 → 4; `editor_inner`'s content match adds the Layout arm and shifts Publish to index 3 (kept net-neutral against the ceiling). Ribbon-tab tests updated. - 2 app-custom page-rect glyph icons + i18n strings. All three crates' suites green (514); fmt + clippy clean; ceiling passes.

Tested by `continuous_section_shares_previous_page` and `continuous_multi_column_section_flows_into_two_columns_on_shared_page` (layout) + `section_type_maps_to_section_start` (DOCX mapper). **Limitations:** continuous columns are filled top-to-bottom (fill-first, no height *balancing* — Word balances continuous-section columns evenly); `evenPage`/`oddPage` start a new page like `nextPage` (the blank-page insertion to reach an even/odd page is not yet emitted); and unequal column widths (`w:cols w:equalWidth="0"`) render as equal columns (per-column widths are not modelled). | | **Document Metadata** | Yes | — | Yes | Core properties (title, subject, keywords, description, creator, last-modified-by, created/modified dates, language, revision) round-trip in both formats — DOCX via `docProps/core.xml` (OPC `CoreProperties`; the `serde` feature on `loki-opc` is enabled so the reader/writer are real, not stubs), ODT via `meta.xml`. **Extended Dublin Core** (publisher, contributors, rights, license, identifier, identifier-scheme, type, format, source, relation, coverage, issued, bibliographic-citation) round-trips too: `dc:identifier` uses the native core.xml element; the rest are carried as DOCX `docProps/custom.xml` custom properties / ODT `meta:user-defined` entries under reserved `dcmi:` names. The flattening is shared via `DublinCoreMeta::to_named_pairs`/`from_named_pairs` in `loki-doc-model`. Tested by `metadata_round_trip.rs` (DOCX) and `extended_dublin_core_round_trips` (ODT). Not yet written: custom user properties, `meta:editing-duration`, OOXML `docProps/app.xml`. | | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`). At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. | diff --git a/loki-doc-model/src/lib.rs b/loki-doc-model/src/lib.rs index 996d3b22..6a755bd8 100644 --- a/loki-doc-model/src/lib.rs +++ b/loki-doc-model/src/lib.rs @@ -153,11 +153,11 @@ pub use loro_mutation::{ insert_text_at, mark_text_at, }; pub use loro_mutation::{ - MutationError, clear_block_list, delete_block, delete_text, get_block_alignment, - get_block_alignment_at, get_block_list_id, get_block_style_name, get_block_text, get_mark_at, - insert_text, mark_text, merge_block, merge_block_at, replace_text, set_block_alignment, - set_block_alignment_at, set_block_style, set_block_type_heading, set_block_type_para, - split_block, split_block_at, + MutationError, clear_block_list, delete_block, delete_text, document_is_landscape, + get_block_alignment, get_block_alignment_at, get_block_list_id, get_block_style_name, + get_block_text, get_mark_at, insert_text, mark_text, merge_block, merge_block_at, replace_text, + set_block_alignment, set_block_alignment_at, set_block_style, set_block_type_heading, + set_block_type_para, set_document_orientation, split_block, split_block_at, }; #[cfg(feature = "serde")] pub use loro_mutation::{ diff --git a/loki-doc-model/src/loro_mutation/mod.rs b/loki-doc-model/src/loro_mutation/mod.rs index 84797077..8c988aca 100644 --- a/loki-doc-model/src/loro_mutation/mod.rs +++ b/loki-doc-model/src/loro_mutation/mod.rs @@ -32,6 +32,7 @@ mod block_edit; mod nested; #[cfg(feature = "serde")] mod objects; +mod page; mod selection; mod style; #[cfg(feature = "serde")] @@ -51,6 +52,7 @@ pub use self::nested::{ }; #[cfg(feature = "serde")] pub use self::objects::{insert_inline_image_at, insert_inline_note_at}; +pub use self::page::{document_is_landscape, set_document_orientation}; pub use self::selection::delete_selection_at; pub use self::style::{ clear_block_list, get_block_list_id, get_block_style_name, set_block_style, diff --git a/loki-doc-model/src/loro_mutation/page.rs b/loki-doc-model/src/loro_mutation/page.rs new file mode 100644 index 00000000..7c74a5b3 --- /dev/null +++ b/loki-doc-model/src/loro_mutation/page.rs @@ -0,0 +1,87 @@ +// SPDX-License-Identifier: Apache-2.0 +// Copyright 2026 AppThere Loki contributors + +//!

Model (loki-doc-model, `loro_mutation/page.rs`): - `set_document_margins(loro, top, bottom, left, right)` sets those four edges on every section's margins map (creating it when absent) and leaves header/footer/gutter distances untouched; `document_margins` reads section 0's margins for the active-preset check. Same relayout pipeline as orientation. - 3 round-trip tests (`page_margins.rs`): all-edges update, per-edge differences, header distance preserved. Editor (loki-text, `editor_ribbon_layout.rs`): - Margins group with Normal (72pt) / Narrow (36pt) / Wide (72/72/144/144) presets; the active preset highlights via the pure `margin_matches` (½-pt tolerance for import rounding). The orientation and margin buttons now share a single `apply_and_sync` helper (mutation → relayout → sync). - `layout_tab_content` keeps its 6-arg signature so the ceiling-bound `editor_inner` call site is unchanged. 5 `margin_matches`/preset tests. - 3 app-custom page-inset glyph icons (tooltip-disambiguated) + i18n.

The section break *type* (`w:type` continuous / nextPage / evenPage / oddPage) imports to `Section.start` (`SectionStart`); ODF has no equivalent and always yields `NewPage`. **Mixed page sizes/orientations render correctly:** the editor/print painter sizes each page's white background and drop shadow from that page's own `page.page_size` (via `page_chrome_size`), so an A4 or landscape-Letter section no longer leaves a gray streak. Tested by `page_chrome_uses_per_page_size`. **`continuous` breaks share a page.** Consecutive sections joined by `continuous` breaks are flowed as one **page-sharing group** (`flow::flow_section_group`): the group's first section starts the pages and owns the page geometry + headers/footers (a continuous break cannot change page size), and each continuous member continues on the **same page** below the previous content, switching column layout mid-page via a fresh column band (`FlowState::column_top_y`). So the ACID page-11 "Unequal multi-column text in a continuous section" label is now followed by its two-column content on the same page instead of stranding the heading. Tested by `continuous_section_shares_previous_page` and `continuous_multi_column_section_flows_into_two_columns_on_shared_page` (layout) + `section_type_maps_to_section_start` (DOCX mapper). **Limitations:** continuous columns are filled top-to-bottom (fill-first, no height *balancing* — Word balances continuous-section columns evenly); `evenPage`/`oddPage` start a new page like `nextPage` (the blank-page insertion to reach an even/odd page is not yet emitted); and unequal column widths (`w:cols w:equalWidth="0"`) render as equal columns (per-column widths are not modelled). | | **Document Metadata** | Yes | — | Yes | Core properties (title, subject, keywords, description, creator, last-modified-by, created/modified dates, language, revision) round-trip in both formats — DOCX via `docProps/core.xml` (OPC `CoreProperties`; the `serde` feature on `loki-opc` is enabled so the reader/writer are real, not stubs), ODT via `meta.xml`. **Extended Dublin Core** (publisher, contributors, rights, license, identifier, identifier-scheme, type, format, source, relation, coverage, issued, bibliographic-citation) round-trips too: `dc:identifier` uses the native core.xml element; the rest are carried as DOCX `docProps/custom.xml` custom properties / ODT `meta:user-defined` entries under reserved `dcmi:` names. The flattening is shared via `DublinCoreMeta::to_named_pairs`/`from_named_pairs` in `loki-doc-model`. Tested by `metadata_round_trip.rs` (DOCX) and `extended_dublin_core_round_trips` (ODT). Not yet written: custom user properties, `meta:editing-duration`, OOXML `docProps/app.xml`. | | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`). At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. | diff --git a/loki-doc-model/src/lib.rs b/loki-doc-model/src/lib.rs index 6a755bd8..989c54a7 100644 --- a/loki-doc-model/src/lib.rs +++ b/loki-doc-model/src/lib.rs @@ -154,10 +154,11 @@ pub use loro_mutation::{ }; pub use loro_mutation::{ MutationError, clear_block_list, delete_block, delete_text, document_is_landscape, - get_block_alignment, get_block_alignment_at, get_block_list_id, get_block_style_name, - get_block_text, get_mark_at, insert_text, mark_text, merge_block, merge_block_at, replace_text, - set_block_alignment, set_block_alignment_at, set_block_style, set_block_type_heading, - set_block_type_para, set_document_orientation, split_block, split_block_at, + document_margins, get_block_alignment, get_block_alignment_at, get_block_list_id, + get_block_style_name, get_block_text, get_mark_at, insert_text, mark_text, merge_block, + merge_block_at, replace_text, set_block_alignment, set_block_alignment_at, set_block_style, + set_block_type_heading, set_block_type_para, set_document_margins, set_document_orientation, + split_block, split_block_at, }; #[cfg(feature = "serde")] pub use loro_mutation::{ diff --git a/loki-doc-model/src/loro_mutation/mod.rs b/loki-doc-model/src/loro_mutation/mod.rs index 8c988aca..b5078324 100644 --- a/loki-doc-model/src/loro_mutation/mod.rs +++ b/loki-doc-model/src/loro_mutation/mod.rs @@ -52,7 +52,9 @@ pub use self::nested::{ }; #[cfg(feature = "serde")] pub use self::objects::{insert_inline_image_at, insert_inline_note_at}; -pub use self::page::{document_is_landscape, set_document_orientation}; +pub use self::page::{ + document_is_landscape, document_margins, set_document_margins, set_document_orientation, +}; pub use self::selection::delete_selection_at; pub use self::style::{ clear_block_list, get_block_list_id, get_block_style_name, set_block_style, diff --git a/loki-doc-model/src/loro_mutation/page.rs b/loki-doc-model/src/loro_mutation/page.rs index 7c74a5b3..4203674a 100644 --- a/loki-doc-model/src/loro_mutation/page.rs +++ b/loki-doc-model/src/loro_mutation/page.rs @@ -15,7 +15,10 @@ use loro::{LoroDoc, LoroMap}; use super::MutationError; -use crate::loro_schema::{KEY_LAYOUT, KEY_ORIENTATION, KEY_PAGE_SIZE, KEY_SECTIONS}; +use crate::loro_schema::{ + KEY_LAYOUT, KEY_MARGIN_BOTTOM, KEY_MARGIN_LEFT, KEY_MARGIN_RIGHT, KEY_MARGIN_TOP, KEY_MARGINS, + KEY_ORIENTATION, KEY_PAGE_SIZE, KEY_SECTIONS, +}; /// Reads a nested `LoroMap` child by key. fn child_map(map: &LoroMap, key: &str) -> Option { @@ -85,3 +88,61 @@ pub fn set_document_orientation(loro: &LoroDoc, landscape: bool) -> Result<(), M } Ok(()) } + +/// Section 0's page margins in points as `(top, bottom, left, right)`, or `None` +/// when there is no margins map.

Model (loki-doc-model, `loro_mutation/page.rs`): - `set_document_page_size(loro, portrait_w, portrait_h)` sets every section's page size, **preserving each section's orientation** — a landscape section keeps the long edge as its width, so choosing "A4" while landscape gives A4 landscape, not portrait. `document_page_size` reads section 0's size for the active-preset check. Same relayout pipeline as orientation/margins. - 3 round-trip tests (`page_size.rs`): portrait A4, orientation preservation, and Letter→A4 switch. Editor (loki-text, `editor_ribbon_layout.rs`): - Size group with A4 (595.28×841.89pt) / US Letter (612×792pt) presets; the active size highlights via the pure, orientation-independent `page_size_matches` (compares short/long edges within a point). Reuses the shared `apply_and_sync` helper. 4 preset-match tests. - 2 app-custom page-rect glyph icons (aspect-distinguished, tooltip-backed) + i18n. All three crates' suites green (529); fmt + clippy clean; ceiling passes.

The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Remaining:** columns; the References/Review tabs (need TOC / track-changes mutations). | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index d2406a27..4b558633 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -8,7 +8,7 @@ This is the living source of truth documenting which document features, characte | Feature | Import Supported?

The section break *type* (`w:type` continuous / nextPage / evenPage / oddPage) imports to `Section.start` (`SectionStart`); ODF has no equivalent and always yields `NewPage`. **Mixed page sizes/orientations render correctly:** the editor/print painter sizes each page's white background and drop shadow from that page's own `page.page_size` (via `page_chrome_size`), so an A4 or landscape-Letter section no longer leaves a gray streak. Tested by `page_chrome_uses_per_page_size`. **`continuous` breaks share a page.** Consecutive sections joined by `continuous` breaks are flowed as one **page-sharing group** (`flow::flow_section_group`): the group's first section starts the pages and owns the page geometry + headers/footers (a continuous break cannot change page size), and each continuous member continues on the **same page** below the previous content, switching column layout mid-page via a fresh column band (`FlowState::column_top_y`). So the ACID page-11 "Unequal multi-column text in a continuous section" label is now followed by its two-column content on the same page instead of stranding the heading. Tested by `continuous_section_shares_previous_page` and `continuous_multi_column_section_flows_into_two_columns_on_shared_page` (layout) + `section_type_maps_to_section_start` (DOCX mapper). **Limitations:** continuous columns are filled top-to-bottom (fill-first, no height *balancing* — Word balances continuous-section columns evenly); `evenPage`/`oddPage` start a new page like `nextPage` (the blank-page insertion to reach an even/odd page is not yet emitted); and unequal column widths (`w:cols w:equalWidth="0"`) render as equal columns (per-column widths are not modelled). | | **Document Metadata** | Yes | — | Yes | Core properties (title, subject, keywords, description, creator, last-modified-by, created/modified dates, language, revision) round-trip in both formats — DOCX via `docProps/core.xml` (OPC `CoreProperties`; the `serde` feature on `loki-opc` is enabled so the reader/writer are real, not stubs), ODT via `meta.xml`. **Extended Dublin Core** (publisher, contributors, rights, license, identifier, identifier-scheme, type, format, source, relation, coverage, issued, bibliographic-citation) round-trips too: `dc:identifier` uses the native core.xml element; the rest are carried as DOCX `docProps/custom.xml` custom properties / ODT `meta:user-defined` entries under reserved `dcmi:` names. The flattening is shared via `DublinCoreMeta::to_named_pairs`/`from_named_pairs` in `loki-doc-model`. Tested by `metadata_round_trip.rs` (DOCX) and `extended_dublin_core_round_trips` (ODT). Not yet written: custom user properties, `meta:editing-duration`, OOXML `docProps/app.xml`. | | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`). At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. | diff --git a/loki-doc-model/src/lib.rs b/loki-doc-model/src/lib.rs index 989c54a7..1fa0d9b6 100644 --- a/loki-doc-model/src/lib.rs +++ b/loki-doc-model/src/lib.rs @@ -154,11 +154,11 @@ pub use loro_mutation::{ }; pub use loro_mutation::{ MutationError, clear_block_list, delete_block, delete_text, document_is_landscape, - document_margins, get_block_alignment, get_block_alignment_at, get_block_list_id, - get_block_style_name, get_block_text, get_mark_at, insert_text, mark_text, merge_block, - merge_block_at, replace_text, set_block_alignment, set_block_alignment_at, set_block_style, - set_block_type_heading, set_block_type_para, set_document_margins, set_document_orientation, - split_block, split_block_at, + document_margins, document_page_size, get_block_alignment, get_block_alignment_at, + get_block_list_id, get_block_style_name, get_block_text, get_mark_at, insert_text, mark_text, + merge_block, merge_block_at, replace_text, set_block_alignment, set_block_alignment_at, + set_block_style, set_block_type_heading, set_block_type_para, set_document_margins, + set_document_orientation, set_document_page_size, split_block, split_block_at, }; #[cfg(feature = "serde")] pub use loro_mutation::{ diff --git a/loki-doc-model/src/loro_mutation/mod.rs b/loki-doc-model/src/loro_mutation/mod.rs index b5078324..f5c2f9b5 100644 --- a/loki-doc-model/src/loro_mutation/mod.rs +++ b/loki-doc-model/src/loro_mutation/mod.rs @@ -53,7 +53,8 @@ pub use self::nested::{ #[cfg(feature = "serde")] pub use self::objects::{insert_inline_image_at, insert_inline_note_at}; pub use self::page::{ - document_is_landscape, document_margins, set_document_margins, set_document_orientation, + document_is_landscape, document_margins, document_page_size, set_document_margins, + set_document_orientation, set_document_page_size, }; pub use self::selection::delete_selection_at; pub use self::style::{ diff --git a/loki-doc-model/src/loro_mutation/page.rs b/loki-doc-model/src/loro_mutation/page.rs index 4203674a..f93b5053 100644 --- a/loki-doc-model/src/loro_mutation/page.rs +++ b/loki-doc-model/src/loro_mutation/page.rs @@ -146,3 +146,58 @@ pub fn set_document_margins( } Ok(()) } + +/// Section 0's page size in points as `(width, height)`, or `None` when there +/// is no page-size map.

Model (loki-doc-model, `loro_mutation/page.rs`): - `set_document_columns(loro, count)` sets every section's column count (clamped ≥1). A newly-created columns map gets a default 0.5in gap and no separator; an existing one keeps its gap/separator so only the count changes. `document_column_count` reads section 0's count (1 when absent). Same relayout pipeline — in paginated mode the flow engine divides the content into that many columns. - 5 round-trip tests (`page_columns.rs`): fresh doc is single-column, two-columns creates a gap, changing count preserves the gap, back-to-one, and zero clamps to one. Editor (loki-text, `editor_ribbon_layout.rs`): - Columns group with One/Two/Three presets; active state is the exact count. Reuses the shared `apply_and_sync` helper. 3 app-custom page + divider-line glyph icons + i18n. The Layout tab now offers Orientation + Margins + Size + Columns. All three crates' suites green (534); fmt + clippy clean; ceiling passes.

Tested by `page_chrome_uses_per_page_size`. **`continuous` breaks share a page.** Consecutive sections joined by `continuous` breaks are flowed as one **page-sharing group** (`flow::flow_section_group`): the group's first section starts the pages and owns the page geometry + headers/footers (a continuous break cannot change page size), and each continuous member continues on the **same page** below the previous content, switching column layout mid-page via a fresh column band (`FlowState::column_top_y`).

Above/left insert at the caret's own row/col index, below/right at index+1; caret_flat_after re-homes the caret (above shifts it down a row, left shifts it one column right). Two app-custom glyphs for the above/left buttons. Tests: 3 highlight apply/read/round-trip + 2 new caret-math cases.

Each group declares GroupMetrics { priority, full_px, condensed_px }; the engine degrades gracefully by condensing all groups (lowest priority first) before overflowing any into the "More" menu, and falls back to horizontal scroll only when even the fully-overflowed strip cannot fit (§7 steps 1-4). The decision is hysteretic, mirroring Spec 03's page_fit: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by RIBBON_COLLAPSE_HYSTERESIS_PX, so dragging a window across a fit threshold does not thrash; resolution is idempotent at a fixed width (the resolved level feeds back in as prev_level). New tokens RIBBON_OVERFLOW_BUTTON_PX and RIBBON_COLLAPSE_HYSTERESIS_PX; 10 unit tests covering full-fit, priority-ordered condense/overflow, the scroll floor, the hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. Remaining for M3: per-group width measurement wiring into AtRibbon, the condensed + overflow-menu UI representations, and R-13e select-width.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Remaining:** per-group width *measurement* wiring into `AtRibbon` (Blitz layout surface), the condensed group + overflow-menu *UI* representations, and R-13e select-width handling in the condensed state. | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`).

It is resilient like use_breakpoint: with no responsive context the width is treated as unbounded, so every group stays Full and Presentation/Spreadsheet get a sane full-chrome ribbon. 2. The condensed group representation (§7 step 2) is a pure, tested decision — group_layout(collapse, has_label) -> GroupLayout — that AtRibbonGroup applies through a new defaulted `collapse` prop: Full keeps the label and roomy padding, Condensed drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), Overflow renders nothing in the strip. The prop defaults to Full, so every existing call site is unchanged. +3 group_layout tests (13 total in ribbon_collapse_tests). Remaining for M3: per-group width measurement into GroupMetrics + the AtRibbon API change threading a structured group list through the hook, the overflow ("More") menu UI, and R-13e select-width in the condensed state.

(b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Remaining:** per-group width *measurement* into `GroupMetrics` and the `AtRibbon` API change that threads a structured group list + per-app tab metrics through `use_ribbon_cascade` (Write/Insert/Layout/Publish); the overflow ("More") menu *UI* that hosts overflowed groups; and R-13e select-width handling in the condensed state. | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`).

A tab hands it a Vec; it runs use_ribbon_cascade once for the whole strip, renders each group at its resolved Full/Condensed state, and moves overflowed groups into a trailing "More" menu — an upward position: absolute dropdown (confirmed working in Blitz) that renders the overflowed groups in Full form. Group widths are declared, not Blitz-measured (per-element measurement is unreliable): estimate_group_metrics(priority, buttons, has_label) derives the full/condensed widths from the touch-button count. The Layout tab is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through AtRibbonGroups, driven live off the editor's measured viewport width. New LUCIDE_MORE_HORIZONTAL icon and ribbon-overflow-aria string. +2 estimator tests (15 in ribbon_collapse). Remaining for M3: migrate Write/Insert/Publish/Table to RibbonGroupSpec; outside-click dismiss for the More menu (needs a window-level backdrop host — position: fixed collapses to absolute in stylo_taffy); R-13e select-width in the condensed state.

Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **Remaining:** migrate the Write/Insert/Publish/Table tabs to `RibbonGroupSpec` (mechanical, follows the Layout example — the group-helper fns in `editor_ribbon_format`/`_color` still return wrapped `AtRibbonGroup`s and need to expose `(metrics, label, content)` instead); outside-click dismiss for the More menu (needs a window-level backdrop host — `position: fixed` collapses to `absolute` in stylo_taffy, noted `TODO(ribbon)`); and R-13e select-width handling in the condensed state. | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`).

The group-helper fns in editor_ribbon_format / editor_ribbon_color return RibbonGroupSpec (with a threaded priority) instead of a wrapped AtRibbonGroup. Priorities keep the core editing controls (Inline, Alignment, Font, Styles) full the longest; the wide colour-swatch groups overflow first (they also reclaim the most strip width per overflow). R-13e (select-width in the condensed state): AtRibbonGroup now exposes its resolved GroupCollapse to descendants as a *signal* context, and AtRibbonSelect reads it to shrink from RIBBON_SELECT_WIDTH_PX to RIBBON_SELECT_WIDTH_CONDENSED_PX when its group is condensed. A signal (not a plain context value) so prop-memoised selects still re-size reactively when the cascade changes on resize.

Remaining M3 tail: true outside-click-to-dismiss for the More menu needs the menu hosted in a shared window-level overlay so a full-viewport backdrop can span the viewport — position: fixed collapses to absolute in stylo_taffy, so an in-place backdrop can't. Toggle-close and auto-close-on-widen ship today; TODO(ribbon) marks the follow-up.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **Remaining:** migrate the Write/Insert/Publish/Table tabs to `RibbonGroupSpec` (mechanical, follows the Layout example — the group-helper fns in `editor_ribbon_format`/`_color` still return wrapped `AtRibbonGroup`s and need to expose `(metrics, label, content)` instead); outside-click dismiss for the More menu (needs a window-level backdrop host — `position: fixed` collapses to `absolute` in stylo_taffy, noted `TODO(ribbon)`); and R-13e select-width handling in the condensed state. | L | +| 4a.1 | Spec 04 M3 | Width-driven ribbon collapse cascade: condensed variant, overflow menu, per-group priority, hysteresis. **Collapse engine ✅ Started 2026-07-06** — the pure, width-driven cascade core lives in `appthere-ui/src/responsive/ribbon_collapse.rs` (`resolve_cascade(metrics, available_px, prev_level) -> RibbonCascade`): each group declares a `GroupMetrics { priority, full_px, condensed_px }`, and the engine degrades gracefully by **condensing all groups (lowest priority first) before overflowing any** into the "More" menu, falling back to horizontal scroll only when even the fully-overflowed strip can't fit (§7 steps 1–4). Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | diff --git a/loki-text/src/routes/editor/editor_inner.rs b/loki-text/src/routes/editor/editor_inner.rs index 53b1058f..8d426fa5 100644 --- a/loki-text/src/routes/editor/editor_inner.rs +++ b/loki-text/src/routes/editor/editor_inner.rs @@ -41,9 +41,10 @@ use super::editor_metadata_panel::metadata_panel; use super::editor_path_sync::{ PathSyncSignals, restore_session, stash_outgoing, sync_path_and_reset, }; -use super::editor_publish::{publish_panel, publish_tab_content}; +use super::editor_publish::publish_panel; use super::editor_ribbon::write_tab_content; use super::editor_ribbon_insert::insert_tab_content; +use super::editor_ribbon_publish::publish_tab_content; use super::editor_save_banner::save_banner; use super::editor_spell::SpellMenu; use super::editor_state::{EditorState, use_editor_state}; @@ -56,8 +57,7 @@ use crate::tabs::OpenTab; use loki_app_shell::spell::SpellService; // EditorMode removed — the editor is always in edit mode when a document is -// open.

Until now a standalone character style's inspector was blind to the document's docDefaults run defaults — a property unset along the style's own chain resolved to FormatDefault, hiding that Word/ODF supply it from docDefaults. Model (loki-doc-model): - New StyleCatalog::default_character_style (serde-default, so it round-trips through the Loro-bridge catalog JSON and stays back-compatible). - resolve_char_chain falls through to it (first_in_char_chain, cycle/depth-guarded), resolving as Provenance::Default — the character-family analogue of the existing paragraph default path. Importer (loki-ooxml): synthesise a `__DocDefaultChar` character style from w:rPrDefault and point default_character_style at it. Leak fixes: the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (docDefaults are written as w:docDefaults / style:default-style, never as named styles) — this also closes a latent `__DocDefault` paragraph-style export leak. Tests: 4 model (Default fall-through, local-wins) + 3 mapper (synthesis, absence, end-to-end Default provenance). OOXML/ODF/round-trip suites green. Remaining 4a.3: table/list Default sources, character-style editing form, the Page style family, Table conditional/banding, and the Compact-tree breadcrumb (M7).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Remaining:** table-/list-family `Default` sources (same pattern, ODF `style:default-style` import symmetry); **character-style editing form** (the char inspector is still read-only; paragraph editing infra in `editor_style_editor` is the template); **Page** style family (`page_styles` catalog + `PageLayout`/`sectPr` import + DOCX section-export inverse + the flat page panel, ADR-0012 Decision 2); **Table** `TableProps` conditional/banding editing; and the **Compact-tree breadcrumb** (M7). | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-doc-model/src/style/catalog.rs b/loki-doc-model/src/style/catalog.rs index 3f4057a4..eda23b4b 100644 --- a/loki-doc-model/src/style/catalog.rs +++ b/loki-doc-model/src/style/catalog.rs @@ -100,6 +100,18 @@ pub struct StyleCatalog { /// rendering and pagination drift. #[cfg_attr(feature = "serde", serde(default))] pub default_paragraph_style: Option, + /// The id of the document's **default character style** — the character-family + /// analogue of [`default_paragraph_style`](Self::default_paragraph_style).

Remaining 4a.3: table/list Default sources, the Page style family, Table conditional/banding, and the Compact-tree breadcrumb (M7).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`).

charset=UTF-8 Content-Transfer-Encoding: 8bit At Compact the paragraph inheritance tree's full indented list is impractical, so it degrades to a breadcrumb + drill-down (Spec 05 §7/§11): - Breadcrumb: the root→selected path (new model para_breadcrumb = para_ancestors reversed, cycle-guarded), each hop clickable to jump up. - Drill-down: the selected style's direct substyles (para_children), clickable to descend. body::left_column renders this via a new tree_nav.rs when posture.stack (Compact); Expanded/Medium keep the indented tree. Navigation loads the target style's draft exactly as the indented tree does. 1 model test (breadcrumb_is_root_first_including_self); doc-model + loki-text suites green. Remaining 4a.3: table/list Default sources, the Page style family, and Table conditional/banding editing.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`).

This adds the table analogue, the last of the per-family non-paragraph Default sources (ADR-0012 Decision 1): - resolve_table_chain: Local / Inherited / Default / FormatDefault over the table parent chain, with the Default level supplied by a new StyleCatalog::default_table_style (serde-default, round-trips through the Loro-bridge catalog JSON). Plus table_ancestors / table_reparent_cycles for a future table-style editor. - Lives in a new resolve_table.rs so resolve.rs stays at 299 (under the 300 ceiling); the shared Resolved constructors are now pub(crate) for the split. - The OOXML importer records default_table_style from the table style flagged w:default="1" (e.g. TableNormal). Lists are a non-inheriting family per ADR-0012 Decision 2, so a list Default source doesn't apply (Local/FormatDefault only). Table-style export of the default flag is deferred with the wider table-style writer, which isn't built yet. 3 model tests + 2 mapper tests; doc-model + ooxml suites green. Remaining 4a.3: ODF table default-style import symmetry, the Page style family, and Table conditional/banding editing.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1).

charset=UTF-8 Content-Transfer-Encoding: 8bit The model foundation for ADR-0012 Decision 2's page family. - New PageStyle type (style/page_style.rs): a named, NON-inheriting entry (no parent) wrapping the existing rich PageLayout — size, margins, orientation, columns, header/footer master, page numbering. Page styling adopts the ODF model as the unified representation. - New StyleCatalog::page_styles (IndexMap, serde-default so it round-trips through the Loro-bridge catalog JSON and stays back-compatible). - The format-neutral import-mapping core, pure and tested: derive_page_styles(sections) collapses sections with an identical PageLayout into one page style (named PageStyleN in first-seen order, since OOXML has no page-style name), and section_page_style_ids gives the per-section id list — the inverse the DOCX sectPr export needs. No resolver is needed: a non-inheriting family is a chain of length one, so the inspector shows only Local / FormatDefault (per ADR-0012). 7 model tests; full doc-model suite green; loki-ooxml / loki-odf / loki-text / loki-layout all still build against the new catalog field. Remaining page-family work: wire derive_page_styles into the OOXML/ODF importers, the DOCX section-export inverse, ODT native export (style:page-layout + style:master-page), and the flat page panel.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults.

New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Remaining page-family work:** wire `derive_page_styles` into the OOXML/ODF importers (populate `page_styles` on load; ODF carries real `style:master-page` names), the DOCX export inverse (`section_page_style_ids` → `w:sectPr`), ODT native export (`style:page-layout` + `style:master-page`), and the flat page **panel** (browser + geometry inspector, non-inheriting ⇒ flat list). **Remaining 4a.3:** finish the Page family (above); the table family's ODF `style:default-style` import symmetry; and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-doc-model/src/style/catalog.rs b/loki-doc-model/src/style/catalog.rs index 7888f68e..f3be2c31 100644 --- a/loki-doc-model/src/style/catalog.rs +++ b/loki-doc-model/src/style/catalog.rs @@ -13,6 +13,7 @@ use crate::style::char_style::CharacterStyle; use crate::style::list_style::ListStyle; +use crate::style::page_style::PageStyle; use crate::style::para_style::ParagraphStyle; use crate::style::props::char_props::CharProps; use crate::style::props::para_props::ParaProps; @@ -89,6 +90,13 @@ pub struct StyleCatalog { /// Named list styles.

Drift-free by design: the panel DERIVES page styles on demand from the live document's sections (panel_data::page_data -> derive_page_styles) rather than the stored catalog field. The section layouts are the source of truth — the Layout ribbon mutates them directly — so deriving each render keeps the panel from showing stale geometry, the root-cause choice over a stored-but-drifting copy. The inspector rows are pure and tested (style_page_inspector, value-baked like the list inspector: named sizes, uniform-margin collapse). New editing_page_style selection signal wired through the panel; editor_inner held at its 803 baseline via comment tightening; 5 i18n keys. 4 UI tests + the existing model tests; doc-model + loki-text suites green. Remaining page-family work: editing page geometry through the panel (write-back), the DOCX/ODT export naming, and importer population of the stored page_styles field (awaits the section->page-style reference the editing path needs; the panel derives on demand until then).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Remaining page-family work:** wire `derive_page_styles` into the OOXML/ODF importers (populate `page_styles` on load; ODF carries real `style:master-page` names), the DOCX export inverse (`section_page_style_ids` → `w:sectPr`), ODT native export (`style:page-layout` + `style:master-page`), and the flat page **panel** (browser + geometry inspector, non-inheriting ⇒ flat list). **Remaining 4a.3:** finish the Page family (above); the table family's ODF `style:default-style` import symmetry; and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1).

The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Remaining page-family work:** editing page geometry through the panel (write-back); the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the table family's ODF `style:default-style` import symmetry; and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-i18n/i18n/en-US/style.ftl b/loki-i18n/i18n/en-US/style.ftl index 9fefcd43..2618246c 100644 --- a/loki-i18n/i18n/en-US/style.ftl +++ b/loki-i18n/i18n/en-US/style.ftl @@ -35,6 +35,12 @@ style-char-form-heading = Edit character style style-tree-substyles-heading = Substyles # List-styles family list heading (§9 list family, non-inheriting) style-list-family-heading = List styles +# Page-styles family (§9 page family, non-inheriting;

The ODT stylesheet mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points default_character_style at it — so a standalone character style resolves the ODF text defaults as Provenance::Default instead of FormatDefault, exactly as on the DOCX side. The ODT writer already skips `__`-prefixed synthetic styles, so it does not leak. The ODF table default is not wired: OdfDefaultStyle carries no table properties and the ODT mapper does not import table styles at all yet — noted for the wider table-style import, not silently skipped. 1 mapper test incl. an end-to-end Provenance::Default resolution. The mapper's inline test module was extracted to styles_tests.rs (the #[path] idiom) to hold the 300-line ceiling (358 -> 148 production). Full loki-odf suite green.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Remaining page-family work:** editing page geometry through the panel (write-back); the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the table family's ODF `style:default-style` import symmetry; and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1).

Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Remaining page-family work:** editing page geometry through the panel (write-back); the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-odf/src/odt/mapper/styles.rs b/loki-odf/src/odt/mapper/styles.rs index 155ee95d..d8f0c1c6 100644 --- a/loki-odf/src/odt/mapper/styles.rs +++ b/loki-odf/src/odt/mapper/styles.rs @@ -53,6 +53,29 @@ pub(crate) fn map_stylesheet(sheet: &OdfStylesheet) -> StyleCatalog { catalog .paragraph_styles .insert(StyleId::new("__Default"), style); + } else if ds.family == OdfStyleFamily::Text { + // `style:default-style style:family="text"` is the character family's + // `Default` source (ADR-0012 Decision 1) — the ODF symmetry of OOXML's + // synthetic `__DocDefaultChar`.

charset=UTF-8 Content-Transfer-Encoding: 8bit The write-back primitive for LibreOffice-style per-page-style editing: set_page_style_geometry(loro, section_indices, &PageLayout) applies a layout's size / orientation / margins / columns to ONLY the given sections — the ones belonging to a single page style — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. The per-style analogue of the document-wide set_document_* setters. Design: index-targeting rather than a stored Section.page_style reference + renderer refactor. Page styles are already derived by layout-equality (section_page_style_ids), and an edit keeps a style's sections in sync, so targeting by section index is stable — without touching the fragile CRDT section bridge or the layout engine. 3 integration tests (page_style_geometry.rs): edits only its own sections, applies margins + columns, skips out-of-range indices. Next: the panel edit form that computes the target indices + new layout and calls this mutation.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only.

New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Remaining page-family work:** editing page geometry through the panel (write-back); the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1).

This is the per-style analogue of the document-wide `set_document_*` setters.

charset=UTF-8 Content-Transfer-Encoding: 8bit The page panel is now editable per-page-style, the LibreOffice model: selecting a page style shows a preset form (page_form.rs) — Orientation / Size / Margins / Columns buttons matching the Layout ribbon — that applies to ONLY that page style's sections. - apply_preset(&PageLayout, PagePreset) -> PageLayout is a pure, tested transform (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap). - Each button derives the target section indices on demand (panel_data::page_edit_target -> section_page_style_ids) and writes the edited layout through set_page_style_geometry, then relays out. So editing PageStyle1 changes all its pages and leaves PageStyle2 alone. - Buttons highlight the page style's current geometry (is_active). 4 apply_preset tests; full loki-text suite green; every touched file under the 300-line ceiling. Remaining: user-facing page-style naming/rename (auto-named PageStyleN; real ODF master-page names need a stored section->page-style reference — the deferred model refinement).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Remaining page-family work:** the panel edit *form* that calls this mutation; the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Remaining page-family work:** user-facing page-style **naming/rename** (styles are auto-named `PageStyleN`; ODF `style:master-page` names would flow in with a stored section→page-style reference — the deferred model refinement); the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-text/src/routes/editor/editor_style_editor/mod.rs b/loki-text/src/routes/editor/editor_style_editor/mod.rs index 376c9677..b1e17178 100644 --- a/loki-text/src/routes/editor/editor_style_editor/mod.rs +++ b/loki-text/src/routes/editor/editor_style_editor/mod.rs @@ -18,6 +18,7 @@ mod form; mod form_font; mod list_browser; mod page_browser; +mod page_form; mod panel_data; mod posture; mod provenance; @@ -115,6 +116,12 @@ pub(super) fn style_editor_panel( let ds_char_form = Arc::clone(&doc_state); let char_draft = editing_char_draft.read().clone(); let char_form_fonts = Rc::clone(&font_families); + // Editable page form (Spec 05 M6 page family): the selected page style's name + // + current geometry, for the per-page-style preset buttons. + let ds_page_form = Arc::clone(&doc_state); + let page_edit = page_selected + .as_deref() + .and_then(|n| panel_data::page_edit_target(&doc_state, n).map(|(l, _)| (n.to_string(), l))); // Everything the provenance column renders (staged rows, impact preview, // new-style parent default, linked character-style rows) — see `panel_data`. @@ -256,6 +263,9 @@ pub(super) fn style_editor_panel( if let Some(cdraft) = char_draft { { char_form::char_style_form(ds_char_form, editing_char_draft, cdraft, char_form_fonts, sync) } } + if let Some((pname, playout)) = page_edit { + { page_form::page_style_form(&ds_page_form, pname, playout, sync) } + } { family_inspector::family_inspector_columns(char_selected_rows, list_selected_rows, page_selected_rows, posture) } } } diff --git a/loki-text/src/routes/editor/editor_style_editor/page_form.rs b/loki-text/src/routes/editor/editor_style_editor/page_form.rs new file mode 100644 index 00000000..0ee097fd --- /dev/null +++ b/loki-text/src/routes/editor/editor_style_editor/page_form.rs @@ -0,0 +1,254 @@ +// SPDX-License-Identifier: Apache-2.0 + +//!

The Section field rippled to ~15 test literals plus the DOCX-mapper and reflow synthetic-section literals; the two baselined files (docx document.rs, flow.rs) were offset back to their baselines with genuine comment tightening, and assign_page_styles lives in style/page_style.rs so document.rs stays at its baseline. 4 model tests (page_style_model.rs); full doc-model / ooxml / odf / layout suites green; loki-text builds; ceiling gate OK. The panel + edit mutation still derive on demand (consistent names), so these stored refs are the foundation the rename UI and the panel-reads-stored migration build on next.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Remaining page-family work:** user-facing page-style **naming/rename** (styles are auto-named `PageStyleN`; ODF `style:master-page` names would flow in with a stored section→page-style reference — the deferred model refinement); the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults.

So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). *(The panel + edit mutation still derive on demand — consistent names — so the stored refs are the foundation the rename UI + panel-reads-stored migration build on next; the Layout ribbon still edits `section.layout` document-wide, so stored `page_styles` can drift until that migration routes both editors through page styles.)* **Remaining page-family work:** the rename UI + migrating the panel to read the stored refs; the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-doc-model/src/layout/section.rs b/loki-doc-model/src/layout/section.rs index 5381451c..02112b9e 100644 --- a/loki-doc-model/src/layout/section.rs +++ b/loki-doc-model/src/layout/section.rs @@ -13,6 +13,7 @@ use crate::content::attr::ExtensionBag; use crate::content::block::Block; use crate::layout::page::PageLayout; +use crate::style::catalog::StyleId; /// How a section begins relative to the preceding one. /// @@ -49,11 +50,22 @@ pub enum SectionStart { #[cfg_attr(feature = "serde", derive(serde::Serialize, serde::Deserialize))] pub struct Section { /// The page layout applied to this section. + /// + /// When [`page_style`](Self::page_style) names a catalogued page style, this + /// is kept in sync with that style's layout (the effective geometry the + /// renderer reads); it is also the source for an unnamed section. pub layout: PageLayout, /// The block-level content of this section. pub blocks: Vec, /// How this section begins relative to the previous one (`w:sectPr/w:type`). pub start: SectionStart, + /// The named **page style** this section uses (ADR-0012 Decision 2), keyed + /// into [`StyleCatalog::page_styles`](crate::style::StyleCatalog). `None` for + /// a section that has not been assigned a named page style (its inline + /// [`layout`](Self::layout) then stands alone).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). *(The panel + edit mutation still derive on demand — consistent names — so the stored refs are the foundation the rename UI + panel-reads-stored migration build on next; the Layout ribbon still edits `section.layout` document-wide, so stored `page_styles` can drift until that migration routes both editors through page styles.)* **Remaining page-family work:** the rename UI + migrating the panel to read the stored refs; the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (awaits the section→page-style reference the editing path needs — the panel derives on demand until then). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling).

New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible).

So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved).

A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **Remaining page-family work:** the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (`assign_page_styles` normalises on load; native importer-carried names — e.g. ODF master-page names — remain to be wired). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/loki-doc-model/src/lib.rs b/loki-doc-model/src/lib.rs index 17cfbcb6..1203dbb0 100644 --- a/loki-doc-model/src/lib.rs +++ b/loki-doc-model/src/lib.rs @@ -156,10 +156,10 @@ pub use loro_mutation::{ MutationError, clear_block_list, delete_block, delete_text, document_column_count, document_is_landscape, document_margins, document_page_size, get_block_alignment, get_block_alignment_at, get_block_list_id, get_block_style_name, get_block_text, get_mark_at, - insert_text, mark_text, merge_block, merge_block_at, replace_text, set_block_alignment, - set_block_alignment_at, set_block_style, set_block_type_heading, set_block_type_para, - set_document_columns, set_document_margins, set_document_orientation, set_document_page_size, - set_page_style_geometry, split_block, split_block_at, + insert_text, mark_text, merge_block, merge_block_at, rename_page_style, replace_text, + set_block_alignment, set_block_alignment_at, set_block_style, set_block_type_heading, + set_block_type_para, set_document_columns, set_document_margins, set_document_orientation, + set_document_page_size, set_page_style_geometry, split_block, split_block_at, };

Export: new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML NCName via `xml::sanitize_ncname`), so a named or renamed page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to one master page (the first referencing section's layout is the representative geometry — the choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. `content.xml` and `styles.xml` both read from the one resolver so their names always agree. Import: the ODT mapper sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive re-export. OOXML needs nothing further (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them on import). 5 naming unit tests (`page_styles_tests.rs`) + 1 export->import round-trip (`named_page_styles_round_trip_as_master_pages`). Docs + fidelity registry updated.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **Remaining page-family work:** the DOCX export inverse (`section_page_style_ids` → `w:sectPr` is already how sections export today) and ODT native `style:page-layout`+`style:master-page` naming; importer population of the stored `page_styles` field (`assign_page_styles` normalises on load; native importer-carried names — e.g. ODF master-page names — remain to be wired). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1).

Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Remaining page-family work:** OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire); the ODT importer does not yet read `style:display-name` off the master page (the id doubles as the display name today). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index d7ef9093..68321e63 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -23,7 +23,7 @@ This is the living source of truth documenting which document features, characte | **Comments (annotations)** | Yes | Yes | Yes | Round-trip in both formats. The commented range is carried as `Inline::Comment` start/end anchors in the content flow; bodies (author, date, **multi-paragraph block content**) live in `Document.comments`. DOCX uses `w:commentRangeStart`/`w:commentRangeEnd` + a `CommentReference` run, with bodies in `word/comments.xml`; ODF uses inline `office:annotation` (body + `dc:creator`/`dc:date`) / `office:annotation-end`. **Rendered** in paginated mode as a **margin comment panel**: each anchored comment becomes a tinted card (author line + body) stacked in a gutter to the right of the page (`flow_comments.rs`; painted by `loki-vello`, and `loki-text` widens the canvas by `COMMENT_GUTTER_WIDTH` when comments are present). **Persisted through the Loro CRDT** as a JSON snapshot (`loro_bridge::comments`), so comment edits are durable and undoable. Tested by `comments_round_trip.rs` (DOCX), `comments_round_trip` (ODT), `loro_bridge::comments` (CRDT), and `comment_panel_renders_in_gutter` (layout). Limits: inline formatting inside a comment is flattened to plain text; the panel renders on full relayout (not incremental-reuse pages); cross-paragraph comment ranges anchor at the start paragraph. | | **Math (equations)** | Yes | Partial | Yes | Mathematical equations round-trip through both formats. The format-neutral model stores math as a single MathML `` string in `Inline::Math` (the W3C interchange standard and ODF's native form). **DOCX** converts bidirectionally between OMML (`m:oMath` inline / `m:oMathPara` display) and MathML in `loki-ooxml`'s `docx/omml` module; the converter is mutually inverse over the common construct set — text runs (`m:r`/`m:t` ⇄ ``/``/``), fractions (`m:f`), super/subscripts (`m:sSup`/`m:sSub`/`m:sSubSup`), and radicals (`m:rad` ⇄ ``/``). **ODT** embeds the MathML as a formula sub-document (`draw:frame`/`draw:object` → `Object N/content.xml`, listed in the manifest with the `…opendocument.formula` media type) and reads it back, canonicalising on import (`loki-odf`'s `odt::math`); ODF does not distinguish display from inline math, so embedded formulas map to `MathType::InlineMath`. **Persisted through the Loro CRDT** losslessly: a block containing math is preserved as an opaque snapshot. **Rendered** by a first-pass math typesetter (`loki-layout`'s `math` module): the MathML is laid out into positioned glyph runs (tokens shaped via Parley) plus fraction-bar/radical rules, then placed inline via a Parley inline box (the same mechanism as tab stops). Covers identifiers/numbers/operators, rows, fractions (`mfrac`), scripts (`msup`/`msub`/`msubsup`), radicals (`msqrt`/`mroot`), and fenced expressions (`mfenced` / fence-wrapped rows) — reusing the standard `PositionedItem` glyph/rect types so `loki-vello` paints it with no renderer change. **The equation's baseline is aligned to the text baseline** (the inline box reserves the equation's ascent; Parley aligns box bottoms to the baseline, so the descent hangs below into the line like inline text, and the paragraph height grows to cover a deep denominator). **Radical signs and delimiters stretch to their content** via uniform glyph scaling. **Math is set in a serif/math face** (`FontFamily::Source("Cambria Math, STIX Two Math, Latin Modern Math, serif")` in the token shaper) rather than the sans-serif body default, matching Word's Cambria Math. **A paragraph that is solely an equation is centered** (display math): Word renders both `m:oMathPara` and a bare paragraph-level `m:oMath` as a centered display equation, so the DOCX mapper centers a paragraph whose only content (ignoring whitespace) is math when it has no explicit alignment. Tested by `omml_tests` + `math_round_trip.rs` (DOCX), `math_tests` + `math_round_trip.rs` (ODT), the `math::tests` typesetter unit tests (incl. stretch), and `inline_math_emits_typeset_items` / `inline_math_baseline_aligns_with_text` (layout integration). **Approximations / not yet done:** stretchy glyphs widen as they grow (uniform scaling, not true extensible glyphs); inter-atom spacing follows simple proportional gaps rather than the full TeX `mathspacing` table; matrices/n-ary operators/accents are not laid out. The OMML↔MathML converter likewise does not yet cover delimiters, n-ary operators, matrices, or accents (these pass through best-effort), so delimiter rendering currently applies to MathML that already contains fences (e.g. ODT-imported or hand-authored), not DOCX OMML round-trips. | | **Templates (DOTX / OTT)** | Yes | — | Partial | Office `.dotx`/`.dotm` and LibreOffice `.ott` open as new untitled documents (the importers key off the `officeDocument` relationship / accepted template mimetype).

Relayouts to the window width on resize (shell re-emits `onscroll` for scroll containers). The automatic paginated↔reflow switch (Spec 03 M2) is **zoom-aware** (2026-07-06): the status-bar zoom feeds the shared responsive `Viewport::zoom`, so zooming a page past the point a full column fits the viewport flips the editor into reflow instead of forcing horizontal scroll, and zooming back out restores pagination (hysteretic; frozen once the user picks a mode). **Bounded reading measure (Spec 03 M4):** the reflow tile is capped at `MAX_REFLOW_TILE_PX` (820 CSS px) and centred (`margin: auto`) on wide windows, so the line length stays comfortable instead of running edge-to-edge; narrow screens still use their full width. A single `render_layout::{reflow_tile_width_px, reflow_content_width_pt}` feeds paint, hit-test, and keyboard nav so they stay aligned (the HTML fallback references the same constant). Content wider than the viewport (e.g. a fixed-width table) widens the tiles so it is reachable by horizontal scrolling rather than clipped. No headers/footers/page chrome by design; the status-bar page indicator is hidden in reflow. **Editing:** `ContinuousLayout` carries per-paragraph editing data, so click-to-cursor, caret placement/painting, range-selection highlighting (mouse drag-select + Shift+Arrow), and reflow-native arrow / Home / End navigation all work, plus typing/undo/formatting. Selection editing is view-independent and works here too: typing replaces the active selection and Backspace/Delete remove it, incl. multi-block ranges (`delete_selection_at` + `editor_keydown_text.rs`, 2026-07-05). Still missing: touch long-press selection is not wired for reflow. Android CPU builds (no `android_gpu`) fall back to a low-fidelity HTML flow (`reflow_view.rs`) with no caret. | --- diff --git a/loki-odf/src/odt/mapper/document/mod.rs b/loki-odf/src/odt/mapper/document/mod.rs index 4fec1448..d114c875 100644 --- a/loki-odf/src/odt/mapper/document/mod.rs +++ b/loki-odf/src/odt/mapper/document/mod.rs @@ -30,6 +30,7 @@ use loki_doc_model::content::float::FloatWrap; use loki_doc_model::document::Document; use loki_doc_model::layout::section::Section; use loki_doc_model::style::catalog::StyleCatalog; +use loki_doc_model::style::{PageStyle, StyleId}; use loki_primitives::units::Points; use crate::error::OdfWarning; @@ -192,10 +193,12 @@ pub(crate) fn map_document( { let layout = resolve_page_layout_by_name(stylesheet, current_master.as_deref(), &mut ctx); - sections.push(Section::with_layout_and_blocks( - layout, - std::mem::take(&mut current_blocks), - )); + let mut section = + Section::with_layout_and_blocks(layout, std::mem::take(&mut current_blocks)); + // The finished section used `current_master` — store it as the + // section's page style (ADR-0012 Decision 2's ODF-native mapping). + section.page_style = current_master.as_deref().map(StyleId::new); + sections.push(section); current_master = Some(nm.clone()); } @@ -208,11 +211,27 @@ pub(crate) fn map_document( // Flush the final (or only) section. let layout = resolve_page_layout_by_name(stylesheet, current_master.as_deref(), &mut ctx); - sections.push(Section::with_layout_and_blocks(layout, current_blocks)); + let mut section = Section::with_layout_and_blocks(layout, current_blocks); + section.page_style = current_master.as_deref().map(StyleId::new); + sections.push(section); (sections, ctx.warnings, ctx.comments) }; + // ── 4b.

A named page style's human display name now survives an ODT round-trip via `style:display-name`. - `OdfMasterPage` gains a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms. - The mapper carries it onto the imported `PageStyle` only when distinct from the id — a redundant name stays None, and the earlier `Some(id)` fabrication is dropped so a later rename is no longer shadowed. - Export writes `style:display-name` when the catalog gives the style a name distinct from the emitted NCName, so id `WideBody` / display "Wide Body" round-trips both halves. - The self-closing-master reader branch is refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. 1 export unit test + display-name assertions in the round-trip test. Docs + fidelity registry updated; page family now complete.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Remaining page-family work:** OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire); the ODT importer does not yet read `style:display-name` off the master page (the id doubles as the display name today). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 68321e63..70320bc7 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -23,7 +23,7 @@ This is the living source of truth documenting which document features, characte | **Comments (annotations)** | Yes | Yes | Yes | Round-trip in both formats.

Covers identifiers/numbers/operators, rows, fractions (`mfrac`), scripts (`msup`/`msub`/`msubsup`), radicals (`msqrt`/`mroot`), and fenced expressions (`mfenced` / fence-wrapped rows) — reusing the standard `PositionedItem` glyph/rect types so `loki-vello` paints it with no renderer change. **The equation's baseline is aligned to the text baseline** (the inline box reserves the equation's ascent; Parley aligns box bottoms to the baseline, so the descent hangs below into the line like inline text, and the paragraph height grows to cover a deep denominator). **Radical signs and delimiters stretch to their content** via uniform glyph scaling. **Math is set in a serif/math face** (`FontFamily::Source("Cambria Math, STIX Two Math, Latin Modern Math, serif")` in the token shaper) rather than the sans-serif body default, matching Word's Cambria Math. **A paragraph that is solely an equation is centered** (display math): Word renders both `m:oMathPara` and a bare paragraph-level `m:oMath` as a centered display equation, so the DOCX mapper centers a paragraph whose only content (ignoring whitespace) is math when it has no explicit alignment. Tested by `omml_tests` + `math_round_trip.rs` (DOCX), `math_tests` + `math_round_trip.rs` (ODT), the `math::tests` typesetter unit tests (incl. stretch), and `inline_math_emits_typeset_items` / `inline_math_baseline_aligns_with_text` (layout integration). **Approximations / not yet done:** stretchy glyphs widen as they grow (uniform scaling, not true extensible glyphs); inter-atom spacing follows simple proportional gaps rather than the full TeX `mathspacing` table; matrices/n-ary operators/accents are not laid out. The OMML↔MathML converter likewise does not yet cover delimiters, n-ary operators, matrices, or accents (these pass through best-effort), so delimiter rendering currently applies to MathML that already contains fences (e.g. ODT-imported or hand-authored), not DOCX OMML round-trips. | | **Templates (DOTX / OTT)** | Yes | — | Partial | Office `.dotx`/`.dotm` and LibreOffice `.ott` open as new untitled documents (the importers key off the `officeDocument` relationship / accepted template mimetype).

Relayouts to the window width on resize (shell re-emits `onscroll` for scroll containers). The automatic paginated↔reflow switch (Spec 03 M2) is **zoom-aware** (2026-07-06): the status-bar zoom feeds the shared responsive `Viewport::zoom`, so zooming a page past the point a full column fits the viewport flips the editor into reflow instead of forcing horizontal scroll, and zooming back out restores pagination (hysteretic; frozen once the user picks a mode). **Bounded reading measure (Spec 03 M4):** the reflow tile is capped at `MAX_REFLOW_TILE_PX` (820 CSS px) and centred (`margin: auto`) on wide windows, so the line length stays comfortable instead of running edge-to-edge; narrow screens still use their full width. A single `render_layout::{reflow_tile_width_px, reflow_content_width_pt}` feeds paint, hit-test, and keyboard nav so they stay aligned (the HTML fallback references the same constant). Content wider than the viewport (e.g. a fixed-width table) widens the tiles so it is reachable by horizontal scrolling rather than clipped. No headers/footers/page chrome by design; the status-bar page indicator is hidden in reflow. **Editing:** `ContinuousLayout` carries per-paragraph editing data, so click-to-cursor, caret placement/painting, range-selection highlighting (mouse drag-select + Shift+Arrow), and reflow-native arrow / Home / End navigation all work, plus typing/undo/formatting. Selection editing is view-independent and works here too: typing replaces the active selection and Backspace/Delete remove it, incl. multi-block ranges (`delete_selection_at` + `editor_keydown_text.rs`, 2026-07-05). Still missing: touch long-press selection is not wired for reflow. Android CPU builds (no `android_gpu`) fall back to a low-fidelity HTML flow (`reflow_view.rs`) with no caret. | --- diff --git a/loki-odf/src/odt/mapper/document/document_tests.rs b/loki-odf/src/odt/mapper/document/document_tests.rs index b8d8db38..8b3f110d 100644 --- a/loki-odf/src/odt/mapper/document/document_tests.rs +++ b/loki-odf/src/odt/mapper/document/document_tests.rs @@ -452,6 +452,7 @@ fn stylesheet_with_page_num_format(num_format: Option<&str>) -> OdfStylesheet { }); sheet.master_pages.push(OdfMasterPage { name: "Standard".into(), + display_name: None, page_layout_name: "PL1".into(), header: None, footer: None, diff --git a/loki-odf/src/odt/mapper/document/mod.rs b/loki-odf/src/odt/mapper/document/mod.rs index d114c875..ca90a3f9 100644 --- a/loki-odf/src/odt/mapper/document/mod.rs +++ b/loki-odf/src/odt/mapper/document/mod.rs @@ -226,7 +226,16 @@ pub(crate) fn map_document( if let Some(id) = §ion.page_style { catalog.page_styles.entry(id.clone()).or_insert_with(|| { let mut ps = PageStyle::new(id.clone(), section.layout.clone()); - ps.display_name = Some(id.as_str().to_string()); + // Carry the master page's `style:display-name` when it declares + // one distinct from its `style:name`; else leave None (the id is + // the UI label).

Model (loki-doc-model): - content/toc.rs: pure, tested builders — `heading_outline` collects (level, label) for each Block::Heading within a depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a TableOfContentsBlock whose cached body is level-indented entry paragraphs. Page numbers are omitted (they need the paginated layout — like a freshly-inserted Word TOC field). - loro_mutation/toc.rs: `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (a guarded no-op on a non-TOC block); `first_toc_block_index` locates it. A TableOfContents round-trips through the bridge as an opaque snapshot, so both are undoable. Layout (loki-layout): fix the root cause that made this (and any imported) TOC invisible — `flow_block`'s `_ => {}` catch-all silently dropped TableOfContents/Index blocks. Both now flow their cached body via a new `flow_blocks` helper that the merged Div/Figure arms also use, so flow.rs holds at its baseline. Regression-tested. UI (loki-text): a new non-contextual References tab (Write/Insert/Layout/ References/Publish; contextual Table now at index 5) with Insert + Update (Update disabled with no TOC). 2 app-custom glyphs; tab-index shift updated in ribbon_tabs / CONTEXTUAL_TAB_INDEX / the tab-content match. Tests: content::toc (7) + loro_mutation::toc (5) + 1 layout regression + updated ribbon-tab tests. 5 i18n keys. Docs + fidelity registry updated. Remaining 4a.2: the Review tab (track-changes).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy).

The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block.

Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **Remaining:** the References/Review tabs (need TOC / track-changes mutations). | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`).

The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Remaining:** the **Review** tab (track-changes: revision markup + accept/reject mutations), the larger remaining half of 4a.2. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`.

At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. **Columns are user-editable** (2026-07-06): the Layout ribbon tab's Columns group (one/two/three) applies `set_document_columns` and relayouts. | | **Headers & Footers** | Yes | Yes | Yes | DOCX export writes all three variants — default, first-page (`w:titlePg`), and even-page (`word/settings.xml` with `w:evenAndOddHeaders`) — as `w:hdr`/`w:ftr` parts with full block content; ODT export writes them into the master page.

Page numbers are **not** included in the snapshot (they need the paginated layout — like a freshly-inserted, not-yet-updated Word TOC field). **Layout / render:** `flow_block` flows the cached body (previously the `_ => {}` catch-all silently dropped `TableOfContents`/`Index` blocks, so imported or inserted TOCs were invisible — fixed with `flow_blocks`; regression-tested). **Export:** ODT writes the body via `text:*` paragraphs; DOCX TOC-field export is not yet written. | | **Footnotes & Endnotes** | Yes | Yes | Yes | Rendered at end of section with separator rules. **DOCX export** writes the reference marker as a `` to the always-emitted `FootnoteReference`/`EndnoteReference` character style (which carries the superscript), matching Word — *not* as an explicit `` on the marker run, which would add a direct run property the source model never had and break round-trip stability. Verified by the Spec 02 import-export-import guard `docx_reference_round_trip_is_stable`. | | **Dynamic Fields** | Yes | Partial | Yes | Import reads **both** field encodings: complex fields (`w:fldChar`/`w:instrText` state machine) and the compact `w:fldSimple` form (`@w:instr` + cached-result runs, including the self-closing variant) — both map to an identical `Inline::Field` (`fld_simple.rs`). Export writes body-text fields as complex fields (with `separate`+result when a snapshot is cached) — PAGE, NUMPAGES, DATE/TIME (incl. `\@` format switch), TITLE, AUTHOR, SUBJECT, FILENAME, NUMWORDS, REF/PAGEREF cross-references, and `Raw` instructions round-trip (`export_fields.rs`). PAGE / NUMPAGES in headers & footers render real per-page values (per-page re-layout in `assign_headers_footers`); body-text fields still *render* snapshots (post-layout computation, ADR-0008, is proposed). | | **Line-boundary Splitting** | — | Yes | — | Paragraphs split cleanly across pages using `ClippedGroup` masks. | diff --git a/loki-doc-model/src/content/mod.rs b/loki-doc-model/src/content/mod.rs index c04a31d1..d71b64e2 100644 --- a/loki-doc-model/src/content/mod.rs +++ b/loki-doc-model/src/content/mod.rs @@ -15,6 +15,7 @@ pub mod field; pub mod float; pub mod inline; pub mod table; +pub mod toc; pub use attr::{ExtensionBag, ExtensionKey, NodeAttr}; pub use block::Block; diff --git a/loki-doc-model/src/content/toc.rs b/loki-doc-model/src/content/toc.rs new file mode 100644 index 00000000..cee55e14 --- /dev/null +++ b/loki-doc-model/src/content/toc.rs @@ -0,0 +1,129 @@ +// SPDX-License-Identifier: Apache-2.0 +// Copyright 2026 AppThere Loki contributors + +//!

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Remaining:** the **Review** tab (track-changes: revision markup + accept/reject mutations), the larger remaining half of 4a.2. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Remaining Review-tab work:** the editor recording edits as tracked when the flag is on (keystroke/delete wiring), rendering insertions (underline + author colour) and deletions (strikethrough) as layout decorations, the CRDT-level accept/reject-at-cursor + accept/reject-all mutations, and the Review ribbon tab (toggle + accept/reject/next). OOXML `w:ins`/`w:del` and ODF change-region import/export also remain. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 3b88db05..055e6d30 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,6 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`). At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. **Columns are user-editable** (2026-07-06): the Layout ribbon tab's Columns group (one/two/three) applies `set_document_columns` and relayouts. | | **Headers & Footers** | Yes | Yes | Yes | DOCX export writes all three variants — default, first-page (`w:titlePg`), and even-page (`word/settings.xml` with `w:evenAndOddHeaders`) — as `w:hdr`/`w:ftr` parts with full block content; ODT export writes them into the master page.

Page numbers are **not** included in the snapshot (they need the paginated layout — like a freshly-inserted, not-yet-updated Word TOC field). **Layout / render:** `flow_block` flows the cached body (previously the `_ => {}` catch-all silently dropped `TableOfContents`/`Index` blocks, so imported or inserted TOCs were invisible — fixed with `flow_blocks`; regression-tested). **Export:** ODT writes the body via `text:*` paragraphs; DOCX TOC-field export is not yet written. | +| **Track Changes (revisions)** | No | No | No | **Model foundation only** (2026-07-07, Review tab 4a.2). A live tracked-change mark — `CharProps::revision` (`RevisionMark { kind: Insertion/Deletion, author, date, id }`) — rides a run as a CRDT mark (`MARK_REVISION`) and survives an edit cycle (round-trip tested); pure `accept_revisions`/`reject_revisions` transforms and a `DocumentSettings.track_changes` flag exist. **Not yet:** the editor recording edits as tracked, rendering (insertion underline + author colour / deletion strikethrough), CRDT accept/reject mutations, the Review ribbon, and OOXML `w:ins`/`w:del` + ODF change-region import/export.

Export writes body-text fields as complex fields (with `separate`+result when a snapshot is cached) — PAGE, NUMPAGES, DATE/TIME (incl. `\@` format switch), TITLE, AUTHOR, SUBJECT, FILENAME, NUMWORDS, REF/PAGEREF cross-references, and `Raw` instructions round-trip (`export_fields.rs`). PAGE / NUMPAGES in headers & footers render real per-page values (per-page re-layout in `assign_headers_footers`); body-text fields still *render* snapshots (post-layout computation, ADR-0008, is proposed). | | **Line-boundary Splitting** | — | Yes | — | Paragraphs split cleanly across pages using `ClippedGroup` masks. | diff --git a/loki-doc-model/src/content/mod.rs b/loki-doc-model/src/content/mod.rs index d71b64e2..3d3563f7 100644 --- a/loki-doc-model/src/content/mod.rs +++ b/loki-doc-model/src/content/mod.rs @@ -14,6 +14,7 @@ pub mod block; pub mod field; pub mod float; pub mod inline; +pub mod revision_ops; pub mod table; pub mod toc; diff --git a/loki-doc-model/src/content/revision_ops.rs b/loki-doc-model/src/content/revision_ops.rs new file mode 100644 index 00000000..cc6369f6 --- /dev/null +++ b/loki-doc-model/src/content/revision_ops.rs @@ -0,0 +1,228 @@ +// SPDX-License-Identifier: Apache-2.0 +// Copyright 2026 AppThere Loki contributors + +//!

Applied to the run's StyleSpan in char_props_to_style_span, so it flows through the existing Parley decoration + brush path; the renderer needs no change. - Because colour/decoration are derived from the mark at layout time, accept/reject (which clears the mark) reverts the run's appearance with nothing stored to undo. 4 unit tests (insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression test. Baselined resolve.rs / lib.rs held at baseline (comment tightened, redundant blank line dropped). Remaining Review-tab work: the editor recording edits as tracked (keystroke/delete wiring), CRDT accept/reject mutations, the Review ribbon, and OOXML/ODF import/export of revisions.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Remaining Review-tab work:** the editor recording edits as tracked when the flag is on (keystroke/delete wiring), rendering insertions (underline + author colour) and deletions (strikethrough) as layout decorations, the CRDT-level accept/reject-at-cursor + accept/reject-all mutations, and the Review ribbon tab (toggle + accept/reject/next). OOXML `w:ins`/`w:del` and ODF change-region import/export also remain. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Remaining Review-tab work:** the editor recording edits as tracked when the flag is on (keystroke/delete wiring → `MARK_REVISION`), the CRDT-level accept/reject-at-cursor + accept/reject-all mutations, and the Review ribbon tab (toggle + accept/reject/next). OOXML `w:ins`/`w:del` and ODF change-region import/export also remain. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy).

The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`).

Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Remaining Review-tab work:** the editor recording edits as tracked when the flag is on (keystroke/delete wiring → `MARK_REVISION`), the CRDT-level accept/reject-at-cursor + accept/reject-all mutations, and the Review ribbon tab (toggle + accept/reject/next). OOXML `w:ins`/`w:del` and ODF change-region import/export also remain. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`).

The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field).

The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested).

New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Remaining Review-tab work:** tracked **deletions** (Backspace/Delete marking existing text struck-through instead of removing, with the caret semantics that implies), the CRDT-level accept/reject-at-cursor + accept/reject-all mutations, and the Review ribbon tab (toggle that flips `track_changes` + accept/reject/next). OOXML `w:ins`/`w:del` and ODF change-region import/export also remain. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 5b16a84b..0414e253 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Root-cause fix: DocumentSettings now round-trips through the Loro CRDT (loro_bridge/settings.rs — a JSON snapshot under KEY_SETTINGS, like metadata/comments). Previously the bridge dropped settings, so the track_changes flag was wiped on the first relayout (which re-derives the document from the CRDT). set_track_changes / document_track_changes flip and read the flag durably — undoable, and it survives relayout and save. A new non-contextual Review tab (Write/Insert/Layout/References/Review/ Publish; contextual Table now at index 6) hosts a Track Changes toggle: its active state reflects the flag, and clicking it routes through set_track_changes + relayout. So the full pipeline works: toggle on → typed text records as a tracked insertion → renders underlined in the author colour. Tests: settings bridge set/get + preserve-others, full-document settings round-trip, updated ribbon-tab tests. 1 app glyph (AT_TRACK_CHANGES), 3 i18n keys. editor_inner match arms compacted to hold the baseline. Remaining Review-tab work: tracked deletions, CRDT accept/reject controls (the pure transforms exist), and OOXML/ODF revision import/export.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Remaining Review-tab work:** tracked **deletions** (Backspace/Delete marking existing text struck-through instead of removing, with the caret semantics that implies), the CRDT-level accept/reject-at-cursor + accept/reject-all mutations, and the Review ribbon tab (toggle that flips `track_changes` + accept/reject/next). OOXML `w:ins`/`w:del` and ODF change-region import/export also remain. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection).

The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Remaining Review-tab work:** tracked **deletions** (Backspace/Delete marking existing text struck-through instead of removing, with the caret semantics that implies), the CRDT-level accept/reject-at-cursor + accept/reject-all controls (the pure model transforms exist; they need CRDT-level application + the ribbon buttons), and OOXML `w:ins`/`w:del` + ODF change-region import/export. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 0414e253..39f21292 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Remaining Review-tab work:** tracked **deletions** (Backspace/Delete marking existing text struck-through instead of removing, with the caret semantics that implies), the CRDT-level accept/reject-at-cursor + accept/reject-all controls (the pure model transforms exist; they need CRDT-level application + the ribbon buttons), and OOXML `w:ins`/`w:del` + ODF change-region import/export. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings.

The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path).

A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change).

New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Remaining Review-tab work:** tracked **deletions** (Backspace/Delete marking existing text struck-through instead of removing, with the caret semantics that implies), per-change accept/reject (at the cursor, vs. all), nested-cell accept/reject, and OOXML `w:ins`/`w:del` + ODF change-region import/export. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 39f21292..cb127972 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

charset=UTF-8 Content-Transfer-Encoding: 8bit Complete track-changes recording — Backspace/Delete now strike text through instead of removing it when tracking is on. - Pure delete_action(existing, tracking): Word semantics — off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already- struck deletion, else mark struck. DeleteAction {HardDelete, MarkDeleted, Skip}. - CRDT tracked_grapheme_delete: reads the target grapheme's MARK_REVISION (get_mark_at_path), applies the decision (delete / mark-deletion / no-op), and returns the action so the editor can place the caret. Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme. - Document::deletion_revision() supplies the author-attributed deletion mark (Some/None doubles as the tracking flag). handle_backspace_key's grapheme path and handle_delete_key both route through it. 5 tests (delete_action truth table, deletion_revision flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). Scope: single-grapheme Backspace/Delete. A selection delete under tracking still hard-deletes (TODO(review-selection-delete)), as does Backspace at a paragraph start (whole-paragraph-mark deletion isn't modelled). Remaining Review-tab work: selection/paragraph-mark tracked deletion, per-change accept/reject, nested-cell accept/reject, and OOXML/ODF revision import/export.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Remaining Review-tab work:** tracked **deletions** (Backspace/Delete marking existing text struck-through instead of removing, with the caret semantics that implies), per-change accept/reject (at the cursor, vs. all), nested-cell accept/reject, and OOXML `w:ins`/`w:del` + ODF change-region import/export. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save).

New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **Remaining Review-tab work:** selection/paragraph-mark tracked deletion, per-change accept/reject (at the cursor, vs. all), nested-cell accept/reject, and OOXML `w:ins`/`w:del` + ODF change-region import/export. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index cb127972..fbf032a6 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **Remaining Review-tab work:** selection/paragraph-mark tracked deletion, per-change accept/reject (at the cursor, vs. all), nested-cell accept/reject, and OOXML `w:ins`/`w:del` + ODF change-region import/export. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection).

Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **Remaining Review-tab work:** the ODF change-region half of import/export; selection/paragraph-mark tracked deletion; and per-change / nested-cell accept/reject. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index fbf032a6..01ca092d 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

ODF splits a change between the document-leading text:tracked-changes table (one text:changed-region per change: text:insertion/text:deletion + office:change-info with dc:creator/ dc:date; a deletion stows its removed text:p content) and body milestones keyed by text:change-id (an insertion is bracketed by text:change-start/text:change-end; a deletion is a single text:change point). - model: OdfChangedRegion/OdfChangeKind in model/revision.rs; OdfBodyChild::TrackedChanges; RevisionStart/End/Point inline variants. - reader: reader/revisions.rs parses the region table; reader/inlines.rs captures the text:change-* milestones (empty or non-empty forms); document.rs dispatches text:tracked-changes. - mapper: map_inline_children is revision-aware — it resolves each milestone against the region map threaded through OdfMappingContext, turning a bracketed range into an insertion-marked run and a deletion point into a struck run re-materialising the region's removed text. - write: write/revisions.rs collects a Changes table during body rendering (flushed right after office:text opens) and write_styled_run emits the milestones for a revision-carrying run; date written verbatim so RFC-3339 round-trips exactly. - test: revision_round_trip.rs asserts an insertion + deletion survive export/re-import with kind, author, date, and text intact. Ceiling held by trimming doc comments in the at-ceiling mapper/document/mod.rs and by making the shared wrap_span/plain_text writers pub(super) rather than duplicating them.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **Remaining Review-tab work:** the ODF change-region half of import/export; selection/paragraph-mark tracked deletion; and per-change / nested-cell accept/reject. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Remaining Review-tab work:** selection/paragraph-mark tracked deletion; and per-change / nested-cell accept/reject. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 01ca092d..22c06415 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

The format-neutral model stores math as a single MathML `` string in `Inline::Math` (the W3C interchange standard and ODF's native form). **DOCX** converts bidirectionally between OMML (`m:oMath` inline / `m:oMathPara` display) and MathML in `loki-ooxml`'s `docx/omml` module; the converter is mutually inverse over the common construct set — text runs (`m:r`/`m:t` ⇄ ``/``/``), fractions (`m:f`), super/subscripts (`m:sSup`/`m:sSub`/`m:sSubSup`), and radicals (`m:rad` ⇄ ``/``). **ODT** embeds the MathML as a formula sub-document (`draw:frame`/`draw:object` → `Object N/content.xml`, listed in the manifest with the `…opendocument.formula` media type) and reads it back, canonicalising on import (`loki-odf`'s `odt::math`); ODF does not distinguish display from inline math, so embedded formulas map to `MathType::InlineMath`. **Persisted through the Loro CRDT** losslessly: a block containing math is preserved as an opaque snapshot. **Rendered** by a first-pass math typesetter (`loki-layout`'s `math` module): the MathML is laid out into positioned glyph runs (tokens shaped via Parley) plus fraction-bar/radical rules, then placed inline via a Parley inline box (the same mechanism as tab stops). Covers identifiers/numbers/operators, rows, fractions (`mfrac`), scripts (`msup`/`msub`/`msubsup`), radicals (`msqrt`/`mroot`), and fenced expressions (`mfenced` / fence-wrapped rows) — reusing the standard `PositionedItem` glyph/rect types so `loki-vello` paints it with no renderer change. **The equation's baseline is aligned to the text baseline** (the inline box reserves the equation's ascent; Parley aligns box bottoms to the baseline, so the descent hangs below into the line like inline text, and the paragraph height grows to cover a deep denominator). **Radical signs and delimiters stretch to their content** via uniform glyph scaling. **Math is set in a serif/math face** (`FontFamily::Source("Cambria Math, STIX Two Math, Latin Modern Math, serif")` in the token shaper) rather than the sans-serif body default, matching Word's Cambria Math. **A paragraph that is solely an equation is centered** (display math): Word renders both `m:oMathPara` and a bare paragraph-level `m:oMath` as a centered display equation, so the DOCX mapper centers a paragraph whose only content (ignoring whitespace) is math when it has no explicit alignment.

The OMML↔MathML converter likewise does not yet cover delimiters, n-ary operators, matrices, or accents (these pass through best-effort), so delimiter rendering currently applies to MathML that already contains fences (e.g. ODT-imported or hand-authored), not DOCX OMML round-trips. | | **Templates (DOTX / OTT)** | Yes | — | Partial | Office `.dotx`/`.dotm` and LibreOffice `.ott` open as new untitled documents (the importers key off the `officeDocument` relationship / accepted template mimetype).

Relayouts to the window width on resize (shell re-emits `onscroll` for scroll containers). The automatic paginated↔reflow switch (Spec 03 M2) is **zoom-aware** (2026-07-06): the status-bar zoom feeds the shared responsive `Viewport::zoom`, so zooming a page past the point a full column fits the viewport flips the editor into reflow instead of forcing horizontal scroll, and zooming back out restores pagination (hysteretic; frozen once the user picks a mode). **Bounded reading measure (Spec 03 M4):** the reflow tile is capped at `MAX_REFLOW_TILE_PX` (820 CSS px) and centred (`margin: auto`) on wide windows, so the line length stays comfortable instead of running edge-to-edge; narrow screens still use their full width. A single `render_layout::{reflow_tile_width_px, reflow_content_width_pt}` feeds paint, hit-test, and keyboard nav so they stay aligned (the HTML fallback references the same constant). Content wider than the viewport (e.g. a fixed-width table) widens the tiles so it is reachable by horizontal scrolling rather than clipped. No headers/footers/page chrome by design; the status-bar page indicator is hidden in reflow. **Editing:** `ContinuousLayout` carries per-paragraph editing data, so click-to-cursor, caret placement/painting, range-selection highlighting (mouse drag-select + Shift+Arrow), and reflow-native arrow / Home / End navigation all work, plus typing/undo/formatting. Selection editing is view-independent and works here too: typing replaces the active selection and Backspace/Delete remove it, incl. multi-block ranges (`delete_selection_at` + `editor_keydown_text.rs`, 2026-07-05). Still missing: touch long-press selection is not wired for reflow.

New CRDT mutation tracked_delete_selection_at (loro_mutation/selection.rs): with a deletion mark it strikes each block's selected slice via strike_range — walking to_delta() and applying delete_action per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and PRESERVES the paragraph marks between selected blocks (no merge, unlike the untracked path). With None it delegates to the existing hard-deleting delete_selection_at; the two now share a normalize_selection front-end. Editor: the single selection-delete choke point delete_selection_in_doc gained a deletion-mark parameter (+ a deletion_mark helper), so Backspace/Delete/Enter-over-selection and replace-typing all strike under tracking — the new typed run is inserted before the struck old text, as Word does. Tests: 5 CRDT tests (loro_tracked_selection_tests.rs) — single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, and None hard-delete+merge. Docs: fidelity-status Track Changes row + deferred-features plan updated; remaining tail is paragraph-mark tracked deletion and per-change / nested-cell accept/reject. Ceiling held by trimming editor_keydown_text comments.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Remaining Review-tab work:** selection/paragraph-mark tracked deletion; and per-change / nested-cell accept/reject. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Remaining Review-tab work:** paragraph-mark tracked deletion (the para break itself — Backspace at a paragraph start still merges); and per-change (at-cursor) / nested-cell accept/reject. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 22c06415..bf4519fc 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Model (loro_mutation/revision.rs): - accept_reject_revision_at(loro, path, byte_offset, accept) finds the contiguous MARK_REVISION span at the caret (span_at: the span containing the offset, else the one ending at it) and resolves it via the shared resolve_span — deleting a removed run's text or clearing a kept run's mark — returning the collapsed caret offset (change start on removal, else unchanged) or None when the caret is not on a change. - revision_at(loro, path, byte_offset) is the read-only query driving the buttons' enabled state. - resolve_text (accept/reject-all) refactored to share revision_spans + resolve_span. UI (editor_ribbon_review.rs): accept_reject_at_caret reads the caret from cursor_state, applies the mutation, relays out, and repositions the caret; the buttons enable only when change_at_caret (revision_at) holds, so they update as the caret moves. Circle-check / circle-x glyphs distinguish the per-change buttons from the plain check/cross all-buttons; 2 i18n keys. Tests: 7 CRDT tests (loro_per_change_revision_tests.rs) — accept/reject × insertion/deletion, no-op off a change, revision_at true/false, and only-the-caret-change-resolved. Docs: fidelity-status Track Changes row + deferred-features plan updated; remaining tail is paragraph-mark tracked deletion and nested-cell revision resolution.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Remaining Review-tab work:** paragraph-mark tracked deletion (the para break itself — Backspace at a paragraph start still merges); and per-change (at-cursor) / nested-cell accept/reject. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Remaining Review-tab work:** paragraph-mark tracked deletion (the para break itself — Backspace at a paragraph start still merges); and nested-cell (table/note) revision resolution — accept/reject and per-change both operate on top-level block text. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index bf4519fc..d8485388 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

The per-change ops (accept_reject_revision_at / revision_at) were already path-aware, so they resolve nested changes without change. Tests: 3 CRDT tests (loro_nested_revision_tests.rs) — accept keeps / reject removes a table-cell change, and accept resolves a footnote-body change, each asserting the document ends clean (!has_tracked_changes). Docs: fidelity-status Track Changes row + deferred-features plan updated; the remaining Review tail is paragraph-mark tracked deletion.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Remaining Review-tab work:** paragraph-mark tracked deletion (the para break itself — Backspace at a paragraph start still merges); and nested-cell (table/note) revision resolution — accept/reject and per-change both operate on top-level block text. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Remaining Review-tab work:** paragraph-mark tracked deletion (the para break itself — Backspace at a paragraph start still merges). | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index d8485388..f5ccc571 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

charset=UTF-8 Content-Transfer-Encoding: 8bit The last Review tail. A paragraph's terminating mark (¶) is modelled by its direct_char_props (the OOXML w:pPr/w:rPr slot), so a tracked ¶-deletion is a Deletion on direct_char_props.revision — no new model type. Backspace at the start of a top-level paragraph under track changes now records this instead of merging; accept-all removes the ¶ (paragraphs merge), reject-all clears it. - round-trip: the bridge dropped block-level char-props `revision`; map_char_props_to_map / reconstruct_char_props_from_map now write/read it under a new PROP_REVISION key so it survives the CRDT. - record: new loro_mutation/para_mark.rs::set_para_mark_deletion marks the previous paragraph's ¶ (upgrading a plain para -> styled_para like alignment), declining non-paragraphs so the caller hard-merges. - resolve: accept_reject_all_revisions also sweeps para-marks (para_mark::resolve_para_marks, recursing into cells/notes) — accept merges the successor via merge_block_in_list, reject clears. The pure transforms merge too (content/para_mark_merge.rs, shared by resolve_blocks). has_revisions detects a para-mark so the buttons enable. - editor: Backspace's block/grapheme paths extracted to editor_keydown_backspace.rs (holds the 300-line ceiling); the at-start branch routes a top-level paragraph through the tracked recording. Tests: 8 CRDT/model tests (loro_para_mark_revision_tests.rs) — round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability. Deferred (noted): rendering a struck ¶ glyph; OOXML/ODF export of the para-mark deletion; nested-container recording (TODO(review-para-mark-nested)); per-change resolution of a para mark. The Review tab is now feature-complete for the editor path. Docs: fidelity-status Track Changes row + deferred-features plan updated.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Remaining Review-tab work:** paragraph-mark tracked deletion (the para break itself — Backspace at a paragraph start still merges). | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; OOXML/ODF export of the para-mark deletion; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index f5ccc571..ee7bb5e1 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. **Columns are user-editable** (2026-07-06): the Layout ribbon tab's Columns group (one/two/three) applies `set_document_columns` and relayouts. | | **Headers & Footers** | Yes | Yes | Yes | DOCX export writes all three variants — default, first-page (`w:titlePg`), and even-page (`word/settings.xml` with `w:evenAndOddHeaders`) — as `w:hdr`/`w:ftr` parts with full block content; ODT export writes them into the master page. Round-trip tested (`even_page_headers_footers_round_trip`). | | **Table of Contents** | Yes | Yes | Yes (ODT) | A `Block::TableOfContents` carries a cached snapshot of level-indented entry paragraphs. **Generated in-editor** (2026-07-07, References ribbon tab): `content::toc::build_toc` walks the document's `Block::Heading`s (down to a depth, default 3) into entry paragraphs; `insert_table_of_contents` inserts one at the caret and `refresh_table_of_contents` rebuilds the snapshot ("update field"). Page numbers are **not** included in the snapshot (they need the paginated layout — like a freshly-inserted, not-yet-updated Word TOC field). **Layout / render:** `flow_block` flows the cached body (previously the `_ => {}` catch-all silently dropped `TableOfContents`/`Index` blocks, so imported or inserted TOCs were invisible — fixed with `flow_blocks`; regression-tested). **Export:** ODT writes the body via `text:*` paragraphs; DOCX TOC-field export is not yet written. | -| **Track Changes (revisions)** | Partial | Partial | Partial | **Model + render** (2026-07-07, Review tab 4a.2).

No ¶ glyph is painted, so a recorded para-mark deletion is invisible until reviewed. **DOCX import/export** (2026-07-07): tracked runs round-trip through OOXML — `w:ins`/`w:del` wrappers carry `w:id`/`w:author`/`w:date`, deleted text is written as `w:delText`, and both map to/from `CharProps::revision` (`revision_round_trip.rs`). **ODT import/export** (2026-07-07): tracked runs round-trip through ODF's change model — a leading `text:tracked-changes` table holds one `text:changed-region` per change (`text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text), and the body brackets an insertion with `text:change-start`/`text:change-end` and marks a deletion with a `text:change` point, all keyed by `text:change-id` (`loki-odf`'s `revision_round_trip.rs`). **Remaining tails:** a struck paragraph mark is not yet *rendered* (no ¶ glyph) and is not exported to OOXML `w:pPr/w:rPr/w:del` / ODF; recording a para-mark deletion inside a table cell / note body still hard-merges (`TODO(review-para-mark-nested)`), and the per-change buttons act on text runs only (a para mark is resolved via accept-all/reject-all). (The older opaque `TrackedChange` type is for format round-trip only and stays unwired.) | | **Footnotes & Endnotes** | Yes | Yes | Yes | Rendered at end of section with separator rules. **DOCX export** writes the reference marker as a `` to the always-emitted `FootnoteReference`/`EndnoteReference` character style (which carries the superscript), matching Word — *not* as an explicit `` on the marker run, which would add a direct run property the source model never had and break round-trip stability.

Export writes body-text fields as complex fields (with `separate`+result when a snapshot is cached) — PAGE, NUMPAGES, DATE/TIME (incl. `\@` format switch), TITLE, AUTHOR, SUBJECT, FILENAME, NUMWORDS, REF/PAGEREF cross-references, and `Raw` instructions round-trip (`export_fields.rs`). PAGE / NUMPAGES in headers & footers render real per-page values (per-page re-layout in `assign_headers_footers`); body-text fields still *render* snapshots (post-layout computation, ADR-0008, is proposed). | | **Line-boundary Splitting** | — | Yes | — | Paragraphs split cleanly across pages using `ClippedGroup` masks. | diff --git a/loki-doc-model/src/content/mod.rs b/loki-doc-model/src/content/mod.rs index 3d3563f7..55b239dc 100644 --- a/loki-doc-model/src/content/mod.rs +++ b/loki-doc-model/src/content/mod.rs @@ -14,6 +14,7 @@ pub mod block; pub mod field; pub mod float; pub mod inline; +mod para_mark_merge; pub mod revision_ops; pub mod table; pub mod toc; diff --git a/loki-doc-model/src/content/para_mark_merge.rs b/loki-doc-model/src/content/para_mark_merge.rs new file mode 100644 index 00000000..93cb27cf --- /dev/null +++ b/loki-doc-model/src/content/para_mark_merge.rs @@ -0,0 +1,71 @@ +// SPDX-License-Identifier: Apache-2.0 +// Copyright 2026 AppThere Loki contributors + +//!

The mark is OOXML w:pPr/w:rPr/w:del — the run properties of the paragraph mark itself carry a w:del. - export: write/revision.rs::write_mark_del emits the self-closing / inside the paragraph mark's w:rPr; a new shared write_rev_element backs both it and the run-wrapping open(). - import: parse_rpr_element recognises a w:del/w:ins child of the pPr's rPr via reader/runs.rs::parse_mark_revision into a new DocxMarkRevision on DocxRPr; map_rpr maps it to CharProps.revision. - test: paragraph_mark_deletion_round_trips builds a StyledPara whose mark carries a Deletion revision and asserts kind/author/date survive export + re-import.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; OOXML/ODF export of the para-mark deletion; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index ee7bb5e1..469cf1b0 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 469cf1b0..255d1274 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | -| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). | L | +| 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | | 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 255d1274..1f5ba337 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -14,7 +14,7 @@ This is the living source of truth documenting which document features, characte | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`).

No ¶ glyph is painted, so a recorded para-mark deletion is invisible until reviewed. **It round-trips through DOCX** (2026-07-08): the paragraph mark's `w:pPr/w:rPr` carries a `w:del`/`w:ins` (`DocxMarkRevision`), read back into `direct_char_props.revision` (`paragraph_mark_deletion_round_trips`). **DOCX import/export** (2026-07-07): tracked runs round-trip through OOXML — `w:ins`/`w:del` wrappers carry `w:id`/`w:author`/`w:date`, deleted text is written as `w:delText`, and both map to/from `CharProps::revision` (`revision_round_trip.rs`). **ODT import/export** (2026-07-07): tracked runs round-trip through ODF's change model — a leading `text:tracked-changes` table holds one `text:changed-region` per change (`text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text), and the body brackets an insertion with `text:change-start`/`text:change-end` and marks a deletion with a `text:change` point, all keyed by `text:change-id` (`loki-odf`'s `revision_round_trip.rs`). Recording a para-mark deletion works inside table cells / note bodies too (2026-07-08): Backspace-at-start there records via the path-aware `set_para_mark_deletion_at`, and the accept/reject sweep already recurses into those containers. The **per-change** Accept/Reject buttons resolve a para-mark deletion too (2026-07-08): when the caret sits on a paragraph whose ¶ is struck (and no text-run change is at the caret), they fall back to `accept_reject_para_mark_at` / `para_mark_at`. **Remaining tails:** a struck paragraph mark is not yet *rendered* (no ¶ glyph) and is not exported to **ODF** (DOCX `w:pPr/w:rPr/w:del` now round-trips).

Export writes body-text fields as complex fields (with `separate`+result when a snapshot is cached) — PAGE, NUMPAGES, DATE/TIME (incl. `\@` format switch), TITLE, AUTHOR, SUBJECT, FILENAME, NUMWORDS, REF/PAGEREF cross-references, and `Raw` instructions round-trip (`export_fields.rs`). PAGE / NUMPAGES in headers & footers render real per-page values (per-page re-layout in `assign_headers_footers`); body-text fields still *render* snapshots (post-layout computation, ADR-0008, is proposed). | | **Line-boundary Splitting** | — | Yes | — | Paragraphs split cleanly across pages using `ClippedGroup` masks. | diff --git a/loki-doc-model/src/lib.rs b/loki-doc-model/src/lib.rs index 229cafe5..723111ec 100644 --- a/loki-doc-model/src/lib.rs +++ b/loki-doc-model/src/lib.rs @@ -152,9 +152,9 @@ pub use loro_bridge::{ };

No ¶ glyph is painted, so a recorded para-mark deletion is invisible until reviewed. **It round-trips through DOCX** (2026-07-08): the paragraph mark's `w:pPr/w:rPr` carries a `w:del`/`w:ins` (`DocxMarkRevision`), read back into `direct_char_props.revision` (`paragraph_mark_deletion_round_trips`). **DOCX import/export** (2026-07-07): tracked runs round-trip through OOXML — `w:ins`/`w:del` wrappers carry `w:id`/`w:author`/`w:date`, deleted text is written as `w:delText`, and both map to/from `CharProps::revision` (`revision_round_trip.rs`). **ODT import/export** (2026-07-07): tracked runs round-trip through ODF's change model — a leading `text:tracked-changes` table holds one `text:changed-region` per change (`text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text), and the body brackets an insertion with `text:change-start`/`text:change-end` and marks a deletion with a `text:change` point, all keyed by `text:change-id` (`loki-odf`'s `revision_round_trip.rs`). Recording a para-mark deletion works inside table cells / note bodies too (2026-07-08): Backspace-at-start there records via the path-aware `set_para_mark_deletion_at`, and the accept/reject sweep already recurses into those containers. The **per-change** Accept/Reject buttons resolve a para-mark deletion too (2026-07-08): when the caret sits on a paragraph whose ¶ is struck (and no text-run change is at the caret), they fall back to `accept_reject_para_mark_at` / `para_mark_at`. **Remaining tails (deferred):** a struck paragraph mark is not yet *rendered* — no ¶ glyph is painted, so a recorded para-mark deletion stays invisible until reviewed (`TODO(review-para-mark-render)`; a `loki-layout` change that needs interactive visual verification of caret/hit-test/wrapping, so deferred 2026-07-08). It is also not exported to **ODF** (a deleted paragraph mark is a change-region spanning a paragraph boundary; needs a LibreOffice-compatible encoding — DOCX `w:pPr/w:rPr/w:del` already round-trips).

Export writes body-text fields as complex fields (with `separate`+result when a snapshot is cached) — PAGE, NUMPAGES, DATE/TIME (incl. `\@` format switch), TITLE, AUTHOR, SUBJECT, FILENAME, NUMWORDS, REF/PAGEREF cross-references, and `Raw` instructions round-trip (`export_fields.rs`). PAGE / NUMPAGES in headers & footers render real per-page values (per-page re-layout in `assign_headers_footers`); body-text fields still *render* snapshots (post-layout computation, ADR-0008, is proposed). | | **Line-boundary Splitting** | — | Yes | — | Paragraphs split cleanly across pages using `ClippedGroup` masks. | diff --git a/loki-layout/src/revision_style.rs b/loki-layout/src/revision_style.rs index 0e5ffc4b..95e817b5 100644 --- a/loki-layout/src/revision_style.rs +++ b/loki-layout/src/revision_style.rs @@ -8,6 +8,12 @@ //! through — matching Word / LibreOffice.

This is the prerequisite for table banding / conditional formatting. Rather than add a style_id field to Table (an ~18-site struct-literal ripple across 8 crates), the reference is stored in the table's NodeAttr "style" key — the convention Block::Heading already uses — read via Table::style_name() and written via set_style_name(). - round-trip: it survives the Loro bridge for free (the bridge serialises the table skeleton including node attrs) and DOCX export/import (map_table carries it; the writer emits w:tblStyle before w:tblW). - tests: 2 DOCX round-trip (table_style_round_trip.rs) + 1 CRDT bridge + the no-style case. Ceiling held by trimming comments in the at-baseline mapper/table.rs and write/document.rs. Next in the arc: banding/conditional model + a pure band_shading resolver + the flow.rs cell-paint seam; ODF table:style-name write; tblLook/ tblStylePr/cnfStyle import; and the editing UI.

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Remaining 4a.3:** finish the Page family (above); the ODF **table** default-style import (blocked on ODT table-style import, which doesn't exist yet); and **Table** `TableProps` conditional/banding editing. | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults.

Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Remaining 4a.3:** the rest of the Table-style arc — banding/conditional model on `TableStyle` + a pure `band_shading` resolver + the `flow.rs` cell-paint seam (layout currently reads only direct `CellProps`, consulting no table style); ODF `table:style-name` write; `w:tblLook`/`w:tblStylePr`/`w:cnfStyle` import; and the editing UI.

Model (loki-doc-model/style/table_style.rs): - TableRegion: the twelve OOXML w:tblStylePr regions (first/last row/col, the four corner cells, horizontal/vertical bands) plus WholeTable. - TableConditionalFormat: the per-region formatting (cell shading today). - TableLook: the per-table w:tblLook region flags, with a custom Default matching Word's 04A0 (header row + first column + row banding on). - TableProps gains row_band_size / col_band_size (serde-default). - TableStyle gains conditional: IndexMap (serde-default, so it stays back-compatible through the Loro-bridge catalog JSON). Resolver (loki-doc-model/style/table_banding.rs): - resolve_cell_shading(style, look, row, col, rows, cols) walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table) and resolves per-property: a higher-precedence region defining no shading falls through to the next that does, with TableProps::background_color as the base fallback. - Band membership is index parity over the band-eligible rows/columns, honouring band size and header/footer/first-col exclusion. All pure — no layout or render dependency, so no visual verification is needed. 12 unit tests (banding parity, band size, header/first-col exclusion, corner-needs-both-flags, precedence ordering, out-of-range) plus default_table_look_matches_word_04a0. The ~4 TableStyle/TableProps struct literals across the workspace updated for the new fields. Wiring the flow.rs cell-paint seam, ODF table:style-name write, w:tblLook/w:tblStylePr/w:cnfStyle import, and the editing UI remain as follow-on increments (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Remaining 4a.3:** the rest of the Table-style arc — banding/conditional model on `TableStyle` + a pure `band_shading` resolver + the `flow.rs` cell-paint seam (layout currently reads only direct `CellProps`, consulting no table style); ODF `table:style-name` write; `w:tblLook`/`w:tblStylePr`/`w:cnfStyle` import; and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1).

Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Remaining 4a.3:** the `flow.rs` cell-paint seam (layer band shading under `CellProps` at the `:1912`/`:1934` paint sites — layout currently reads only direct `CellProps`, consulting no table style); ODF `table:style-name` write; `w:tblLook`/`w:tblStylePr`/`w:cnfStyle` import; and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 202ad2a2..58cb6ade 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -83,7 +83,7 @@ This is the living source of truth documenting which document features, characte | **Floating Images / Wrap Mode** | Yes | Yes | No | Anchored (floating) drawings are marked with the `floating` class and carry their **text-wrap mode** (`FloatWrap`: square/tight/through/top-and-bottom/none, side both/left/right/largest, behind-text flag) on the image/figure `NodeAttr`.

Previously the flow engine read only direct CellProps shading and never consulted the table style. New loki-layout `table_shading` module (mirrors resolve.rs's role): - resolve_table_style(catalog, name) — look a table's "style" attr up in the style catalog. - cell_style_shading(style, row, col, rows, cols) — call the doc-model resolver under Word's default w:tblLook (import not yet wired; TODO(table-tbllook-import)). flow.rs (flow_table, Pass 3b): the painted cell background is now `cell.props.background_color.or(table-style banding)` — direct cell shading still wins, but a cell with none falls through to the style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) are unified into a single target-vec selection — a DRY simplification that offsets the new logic and drops flow.rs 1953 -> 1948 (baseline ratcheted). Tests: table_style_banding_shades_the_header_row (a styled 2x2 table with no direct shading paints exactly its 2 header cells) + 3 table_shading unit tests. Full loki-layout suite green; clippy clean; file-ceiling gate holds (lib.rs doc tightened to absorb the new mod). Real documents carry no conditional shading until w:tblStylePr/tblLook import lands; that plus the ODF table:style-name write and the editing UI remain follow-on increments (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Remaining 4a.3:** the `flow.rs` cell-paint seam (layer band shading under `CellProps` at the `:1912`/`:1934` paint sites — layout currently reads only direct `CellProps`, consulting no table style); ODF `table:style-name` write; `w:tblLook`/`w:tblStylePr`/`w:cnfStyle` import; and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family.

Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched.

Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved).

So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field).

Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **Remaining 4a.3:** ODF `table:style-name` write; `w:tblLook`/`w:tblStylePr`/`w:cnfStyle` import (real documents carry no conditional shading until this lands); and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | | 4a.4 | Spec 03 | ~~Metadata-panel label stacking <250 px (R-13g)~~ (✅ **Done 2026-07-06** — `FieldRow` is now a `#[component]` reading `use_viewport()` per ADR-0013; below `METADATA_LABEL_STACK_PX` (250 px) the label stacks above its input via a `flex-direction: column` switch so the input keeps a usable width; pure `stack_labels` helper + 3 tests in `editor_metadata_panel_tests.rs`); responsive doc type-scale (M4); ~~real `Viewport.zoom`~~ (✅ **Done 2026-07-06** — the status-bar zoom now feeds the shared responsive `Viewport::zoom` (`editor_responsive.rs`: pure `zoom_fraction`/`desired_view_mode` helpers wired into effects 2 & 3), so zooming a page past the point it fits flips the page-fit renderer to reflow instead of forcing horizontal scroll; 5 tests in `editor_responsive_tests.rs`). **Remaining:** responsive doc type-scale (M4). | M | | 4a.5 | Spec 04 M6 | Touch posture + ~~cursor-into-new-cell after insert~~ (✅ **Done 2026-07-06** — `insert_table_after_cursor` now returns the first-cell caret (`first_cell_caret` → flat cell 0 / block 0), and the Insert-tab `run_insert` collapses the cursor there after relayout via `set_collapsed_cursor` (page re-derived per 4b.1); footnote leaves the caret at the anchor, matching Word. `InsertResult` enum threads the optional caret target; the async image flow was extracted to `editor_ribbon_insert_image.rs` to hold the ceiling. 3 tests in `editor_insert_tests.rs`). **Remaining:** touch posture. | M | diff --git a/docs/fidelity-status.md b/docs/fidelity-status.md index 58cb6ade..f4a9f0e4 100644 --- a/docs/fidelity-status.md +++ b/docs/fidelity-status.md @@ -83,7 +83,7 @@ This is the living source of truth documenting which document features, characte | **Floating Images / Wrap Mode** | Yes | Yes | No | Anchored (floating) drawings are marked with the `floating` class and carry their **text-wrap mode** (`FloatWrap`: square/tight/through/top-and-bottom/none, side both/left/right/largest, behind-text flag) on the image/figure `NodeAttr`. DOCX `wp:wrapSquare`/`wrapTight`/`wrapThrough`/`wrapTopAndBottom`/`wrapNone` (+ `wrapText` side, anchor `behindDoc`) and ODF `style:wrap` + `style:run-through` both map. **Floats are painted and text wraps beside them** (`flow_float.rs`): for a `Square`/`Tight`/`Through`/non-behind-`None` float the flow engine reserves a side band (float on the left when text occupies the right, and vice-versa; `Both`/`Largest` default to a left float) by widening the paragraph's start/end indent, paints the image in that band, and reserves its height so the next paragraph clears it. Verified against the Word reference on ACID TC-DOCX-023 (margin-anchored image, text wrapping to its right). **Per-line precision:** lines beside the float are narrowed while lines below it reclaim the full column (two-pass `para_band` layout, shared with drop caps) — verified against the Word reference where the text below the image returns to full width. **Cross-paragraph wrap:** a float taller than its anchoring paragraph keeps wrapping the *following* paragraphs (tracked as `flow::float_impl::ActiveFloat`) until its bottom is cleared; bounded to a single page and to consecutive plain paragraphs (a table/list/rule or page break reserves the float's remaining height instead). **Limitations (gap #12):** the live-editor path keeps the uniform-narrow fallback; the tight wrap **contour** is approximated by the bounding box; true `behindDoc` overlap and absolute anchor positioning are not yet done. `TopAndBottom`/behind-text floats still stack as a block.

Reader (docx/reader/styles.rs): a small state machine over table styles collects band sizes (w:tblStyleRowBandSize / w:tblStyleColBandSize), the base whole-table cell shading (w:tcPr/w:shd — scoped by an in_tcpr flag so w:tblPr/w:shd and w:rPr/w:shd don't leak in), and each w:tblStylePr region's cell shading (tracked via current_region from @w:type, reset on close) into new DocxTableStyleProps / DocxTblStylePr model types on DocxStyle. Mapper (docx/mapper/styles.rs): map_table_region maps the twelve OOXML region names to TableRegion (unknown skipped); band sizes + base shading fill (via the existing xml_util::resolve_shading) go into TableProps, and each shaded region into the conditional map (unshaded regions skipped). So a document using a built-in banded style (List Table / Grid Table Accent) now imports its conditional shading and paints banded rows/header under Word's default w:tblLook. The DocxStyle.table field addition rippled to 7 test literals (mechanical table: None). Tests: parses_table_style_banding + non_table_style_has_no_table_props (reader), table_style_conditional_formatting_maps (mapper, incl. unknown-region and unshaded-region skipping). Full loki-ooxml suite green, clippy clean, file-ceiling gate holds. Per-table w:tblLook/w:cnfStyle import, conditional borders/char formatting, ODF table:style-name write + ODT table-style import, and DOCX export of the style definition's conditional formatting remain follow-on increments (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **Remaining 4a.3:** ODF `table:style-name` write; `w:tblLook`/`w:tblStylePr`/`w:cnfStyle` import (real documents carry no conditional shading until this lands); and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Remaining 4a.3:** per-table `w:tblLook`/`w:cnfStyle` import (still assumes Word's default look); conditional borders/character formatting; ODF `table:style-name` write + ODT table-style import; DOCX export of the style *definition's* conditional formatting (only the reference is written today); and the editing UI.

Reader (docx/reader/document.rs): parse_tbl_look reads w:tblLook from either the explicit boolean attributes (w:firstRow / w:noHBand / … — the no*Band flags inverted into positive banding) or the legacy w:val hex bitmask (0x0020…0x0400), into a new DocxTblLook on DocxTblPr. Model (loki-doc-model): a format-neutral codec on TableLook — encode_attr / decode_attr, a six-char 0/1 string that keeps the OOXML bit layout out of the model. Table gains table_look_code / set_table_look_code storing it as an opaque string in the "tbllook" NodeAttr key (round-trips through the Loro bridge like "style"), so content need not depend on style. Mapper (new docx/mapper/table_look.rs): map_tbl_look encodes a DocxTblLook via TableLook; map_table pushes it into the table's attr. Layout: table_shading::table_look decodes the attr (defaulting on absent/malformed) and cell_style_shading now takes the &TableLook, replacing the hard-coded TableLook::default() in flow.rs. 8 tests across the four layers, incl. an end-to-end flow test (table_look_disabling_first_row_suppresses_style_shading). Ceilings held by trimming comments in the at-baseline mapper/table.rs and flow.rs; full loki-ooxml / loki-doc-model / loki-layout suites green; clippy clean. Remaining: w:cnfStyle per-row/cell overrides, conditional borders/char formatting, ODF table:style-name write + ODT import, DOCX export of the style definition + instance tblLook, and the editing UI (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Remaining 4a.3:** per-table `w:tblLook`/`w:cnfStyle` import (still assumes Word's default look); conditional borders/character formatting; ODF `table:style-name` write + ODT table-style import; DOCX export of the style *definition's* conditional formatting (only the reference is written today); and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow).

New write/table_style.rs: - write_table_styles emits each catalog TableStyle as a w:style w:type="table": band sizes -> w:tblPr, base whole-table shading -> w:tcPr/w:shd, and each conditional region -> w:tblStylePr w:type="…" with its own w:tcPr/w:shd. region_ooxml inverts the mapper's map_table_region; the non-exhaustive TableRegion match skips unknown future variants. - write_tbl_look emits the table instance's w:tblLook (both the explicit boolean attributes and the legacy w:val hex bitmask via look_bitmask) from the "tbllook" attr; it takes Option<&str> and no-ops on absent/malformed input. Wiring: write_styles_xml gains a 2-line call; write_table gains a 1-line call after w:tblW (per the schema), keeping write/document.rs at its 1073 baseline. 5 tests: 4 writer unit tests + table_style_banding_and_tbllook_round_trip (a banded style + a non-default look survive export->import intact through both the catalog and the instance attr). Full loki-ooxml suite green, clippy clean, file-ceiling gate holds. Remaining: w:cnfStyle per-row/cell overrides, conditional borders/char formatting, the ODF side (table:style-name write + ODT import), and the editing UI (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **Remaining 4a.3:** `w:cnfStyle` (per-row/cell region overrides); conditional borders/character formatting; ODF `table:style-name` write + ODT table-style import; DOCX export of the style *definition's* conditional formatting **and** the instance's `w:tblLook` (only the `w:tblStyle` reference is written today); and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **Remaining 4a.3:** `w:cnfStyle` (per-row/cell region overrides); conditional borders/character formatting; the ODF side (`table:style-name` write + ODT table-style import); and the editing UI.

charset=UTF-8 Content-Transfer-Encoding: 8bit Begin the ODF side of table styling. ODF has no conditional-region concept — it bakes table shading into per-cell automatic styles (LibreOffice's on-disk model) — and the ODT writer previously emitted with no formatting at all, dropping every cell background on export. AutoStyles::cell_style (odt/write/auto.rs) now emits a deduplicated automatic carrying fo:background-color (TC{n} names, via a co-located emit_cell_properties), and write/tables.rs references it via table:style-name on each shaded cell. ODT import of fo:background-color already existed (map_cell_props reads it into CellProps.background_color), so a shaded cell now round-trips through ODT with no import-side change. 3 tests: cell_style_emits_background_and_dedupes + a_cell_without_shading_gets_no_style (writer unit) + cell_background_round_trips_via_table_cell_style (end-to-end ODT export -> import). Full loki-odf suite (incl. schema validation) green, clippy clean, ceiling holds. Next: resolve a banded table style into per-cell backgrounds at ODT export (so a DOCX-imported banded table exports its bands to ODT), building on this cell-style emitter; then table-level table:style-name and cell borders/padding (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **Remaining 4a.3:** `w:cnfStyle` (per-row/cell region overrides); conditional borders/character formatting; the ODF side (`table:style-name` write + ODT table-style import); and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **ODT cell-shading export ✅ 2026-07-08** — the first ODF-side increment. ODF has no conditional-region concept: it bakes table shading into **per-cell** automatic styles (LibreOffice's on-disk model), and the ODT writer previously emitted `` with no formatting at all. `AutoStyles::cell_style` (`odt/write/auto.rs`) now emits a deduplicated automatic `` carrying `fo:background-color` (`TC{n}` names, co-located `emit_cell_properties`), referenced by `table:style-name` on each shaded cell in `write/tables.rs`. ODT **import** of `fo:background-color` already existed (`map_cell_props` reads it into `CellProps.background_color`), so a shaded cell now round-trips through ODT with no import change. 3 tests: `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer unit) + `cell_background_round_trips_via_table_cell_style` (end-to-end ODT export→import); full loki-odf suite (incl. schema validation) green. **Remaining 4a.3:** ODT export of a DOCX-imported banded table's shading **resolved into per-cell backgrounds** (call `resolve_cell_shading` per cell at ODT export — the next increment, building directly on this cell-style emitter); ODT `table:style-name` (table-level width/align) write; cell **borders**/padding export; `w:cnfStyle`; conditional character formatting; and the editing UI.

Tested by `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer) and `cell_background_round_trips_via_table_cell_style` (end-to-end ODT round-trip). **Not yet:** ODT export of the table-style *definition* / banding **resolved into per-cell shading** (so a DOCX-imported banded table exports its bands to ODT — the next increment), ODT `table:style-name` (table-level) write, cell **borders**/padding export, `w:cnfStyle`, conditional character formatting, and the editing UI. | | **Page Number Format** | Yes | Yes | No | The page-number numbering scheme is imported in **both formats** into `PageLayout.page_number_format` and applied through `FieldContext`: the PAGE field is formatted via the shared list-marker converter (`lowerRoman`→i, ii, iii; `upperRoman`; `lowerLetter`/`upperLetter`); NUMPAGES stays decimal. **DOCX:** `w:pgNumType @w:fmt`/`@w:start` — the section restart (`page_number_start`) also offsets the displayed number from the section's first physical page. **ODT:** `style:num-format` on `style:page-layout-properties` (the active master page's layout) is read into `OdfPageLayout.num_format` and mapped through the same `map_numbering_scheme` helper shared with list numbering; decimal (`"1"`/absent) is left unset (the renderer default). Tested by `substitution_formats_page_number_as_lower_roman` (DOCX), `read_stylesheet_page_layout_num_format` (ODT reader), and `page_num_format_lower_roman_maps`/`page_num_format_upper_alpha_maps`/`page_num_format_decimal_and_absent_stay_none` (ODT mapper). ODT page-number *restart* (the per-paragraph `style:page-number`) remains a follow-up.

Phase 1 resolves under an immutable catalog borrow; phase 2 mints styles under &mut cx.auto, avoiding a borrow conflict. The style catalog reaches the writer via a Cx.table_styles clone (content.rs; the header/footer Cx in styles.rs uses an empty map). AutoStyles::cell_style was generalised to take the resolved Option<&DocumentColor> instead of &CellProps. 1 round-trip test (table_style_banding_resolves_into_per_cell_shading_on _odt_export: a firstRow-banded style with no direct shading → header cells return shaded, body cells not). Full loki-odf suite (incl. schema validation) green, clippy clean, ceiling holds. Remaining: ODT table-level table:style-name (width/align) write, cell borders/padding export, w:cnfStyle, and the editing UI (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **ODT cell-shading export ✅ 2026-07-08** — the first ODF-side increment. ODF has no conditional-region concept: it bakes table shading into **per-cell** automatic styles (LibreOffice's on-disk model), and the ODT writer previously emitted `` with no formatting at all. `AutoStyles::cell_style` (`odt/write/auto.rs`) now emits a deduplicated automatic `` carrying `fo:background-color` (`TC{n}` names, co-located `emit_cell_properties`), referenced by `table:style-name` on each shaded cell in `write/tables.rs`. ODT **import** of `fo:background-color` already existed (`map_cell_props` reads it into `CellProps.background_color`), so a shaded cell now round-trips through ODT with no import change. 3 tests: `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer unit) + `cell_background_round_trips_via_table_cell_style` (end-to-end ODT export→import); full loki-odf suite (incl. schema validation) green. **Remaining 4a.3:** ODT export of a DOCX-imported banded table's shading **resolved into per-cell backgrounds** (call `resolve_cell_shading` per cell at ODT export — the next increment, building directly on this cell-style emitter); ODT `table:style-name` (table-level width/align) write; cell **borders**/padding export; `w:cnfStyle`; conditional character formatting; and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **ODT cell-shading export ✅ 2026-07-08** — the first ODF-side increment. ODF has no conditional-region concept: it bakes table shading into **per-cell** automatic styles (LibreOffice's on-disk model), and the ODT writer previously emitted `` with no formatting at all. `AutoStyles::cell_style` (`odt/write/auto.rs`) now emits a deduplicated automatic `` carrying `fo:background-color` (`TC{n}` names, co-located `emit_cell_properties`), referenced by `table:style-name` on each shaded cell in `write/tables.rs`. ODT **import** of `fo:background-color` already existed (`map_cell_props` reads it into `CellProps.background_color`), so a shaded cell now round-trips through ODT with no import change. 3 tests: `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer unit) + `cell_background_round_trips_via_table_cell_style` (end-to-end ODT export→import); full loki-odf suite (incl. schema validation) green. **ODT banding resolution on export ✅ 2026-07-08** — bridges the two formats' models: a table carrying only a `"style"` reference + `"tbllook"` (e.g. a DOCX-imported banded table) now exports its bands to ODT as concrete per-cell shading. `write/tables.rs` flattens the rows, assigns each cell its grid column (`assign_grid_columns` — a coverage-grid mirror of the layout's `assign_cell_columns`, honouring `col_span`/`row_span` merges), then in a two-phase pass computes each cell's effective background = its direct shading **else** `resolve_cell_shading(style, look, row, col, rows, cols)` (the very doc-model resolver the layout paints with) and bakes it into the per-cell `table-cell` automatic style (phase 1 resolves under an immutable catalog borrow, phase 2 mints styles under `&mut cx.auto` — avoiding a borrow conflict). The style catalog reaches the writer via a `Cx.table_styles` clone (`content.rs`; the header/footer `Cx` in `styles.rs` uses an empty map). `AutoStyles::cell_style` was generalised to take the resolved `Option<&DocumentColor>` rather than `&CellProps`. 1 round-trip test (`table_style_banding_resolves_into_per_cell_shading_on_odt_export`: a firstRow-banded style with no direct shading → header cells return shaded, body cells not). **Remaining 4a.3:** ODT `table:style-name` (table-level width/align) write; cell **borders**/padding export; `w:cnfStyle`; conditional character formatting; and the editing UI.

Verified against the Word reference on ACID TC-DOCX-023 (margin-anchored image, text wrapping to its right). **Per-line precision:** lines beside the float are narrowed while lines below it reclaim the full column (two-pass `para_band` layout, shared with drop caps) — verified against the Word reference where the text below the image returns to full width. **Cross-paragraph wrap:** a float taller than its anchoring paragraph keeps wrapping the *following* paragraphs (tracked as `flow::float_impl::ActiveFloat`) until its bottom is cleared; bounded to a single page and to consecutive plain paragraphs (a table/list/rule or page break reserves the float's remaining height instead). **Limitations (gap #12):** the live-editor path keeps the uniform-narrow fallback; the tight wrap **contour** is approximated by the bounding box; true `behindDoc` overlap and absolute anchor positioning are not yet done. `TopAndBottom`/behind-text floats still stack as a block.

Added shared unescape_text/resolve_general_ref/event_text helpers and fixed all affected loops to match both event kinds and accumulate fragments instead of overwriting. - num-bigint 0.4.7 -> 0.4.8 (drops a yanked release). - Diagnosed RUSTSEC-2023-0071 (rsa Marvin Attack): rsa is an inactive optional dependency of sqlx-mysql, which this workspace's sqlx feature set never enables (postgres only) -- confirmed via `cargo tree -i rsa` returning nothing even against a from-scratch lockfile. No code path is reachable, so there's nothing to vendor-patch; added a documented .cargo/audit.toml ignore with the full diagnosis and a re-verification note instead of maintaining a permanent fork of dead code. - Documented the three remaining vulnerable quick-xml copies that are blocked on upstream (object_store, wayland-scanner, zbus_xml/accesskit) in CLAUDE.md, with exposure analysis for each. cargo check/test/clippy -D warnings/fmt all pass across the workspace; the file-ceiling ratchet has zero growth.

The ODT writer previously emitted with no style-name, so a table's named style was dropped on export. New write/table_style.rs emits a named for each catalog table style (skipping __-prefixed synthetics) into styles.xml's , carrying table-level geometry: style:width (TableProps::width Absolute) / style:rel-width (Percent), table:align, and fo:background-color. write/tables.rs references it via table:style-name on the element. The TableWidth / TableAlignment matches carry a wildcard arm (both enums are #[non_exhaustive]). Import restores the reference in one line: map_table sets Table::set_style_name from OdfTable.style_name, which the reader already parsed. So a table's named style survives an ODT round-trip. 5 tests: 4 writer unit (width/align/background emission, rel-width for percent, no-geometry omits table-properties, synthetics skipped) + table_style_name_reference_round_trips (end-to-end). Full loki-odf suite incl. schema validation green, clippy clean, ceiling holds. Remaining: ODT import of the table-style definition back into the catalog (the reference survives, but width/align/bg are written-but-not-re-read into a TableStyle — needs reader table-properties extraction + a table_styles mapper); cell borders/padding export; and the editing UI (docs updated).

Per-group result is `GroupCollapse::{Full,Condensed,Overflow}`. **Hysteretic** like Spec 03's `page_fit`: it collapses a step the instant the strip overflows but re-expands only when the looser layout clears the width by `RIBBON_COLLAPSE_HYSTERESIS_PX` (32 px), so a window dragged across a fit threshold doesn't thrash; resolution is idempotent at a fixed width (the resolved `level` feeds back in as `prev_level`). New tokens `RIBBON_OVERFLOW_BUTTON_PX` (44) + `RIBBON_COLLAPSE_HYSTERESIS_PX`. 10 unit tests (`ribbon_collapse_tests.rs`) cover full-fit, priority-ordered condense/overflow, the scroll floor, hysteresis dead-band, idempotence, tie-breaking, and the empty ribbon. **Reactive binding + condensed representation ✅ 2026-07-06** — (a) `use_ribbon_cascade(metrics) -> RibbonCascade` binds the engine to the live `AtResponsiveContext` viewport width, holding the resolved `level` in a hook-local signal for hysteresis across resizes; it is **resilient** like `use_breakpoint` (no responsive context ⇒ unbounded width ⇒ every group stays Full, so Presentation/Spreadsheet get a sane full-chrome ribbon). (b) The condensed group representation (§7 step 2) is a pure, tested decision — `group_layout(collapse, has_label) -> GroupLayout { rendered, pad_px, gap_px, show_label }` — that `AtRibbonGroup` now applies via a new defaulted `collapse: GroupCollapse` prop: **Full** keeps the label + roomy padding, **Condensed** drops the label and tightens padding/gap (never the buttons, so 44 px touch targets survive), **Overflow** renders nothing in the strip (the "More" menu hosts it). The prop defaults to Full, so all existing call sites are unchanged. +3 `group_layout` tests (13 total). **Collapse-aware container + overflow menu + first migration ✅ 2026-07-06** — a new shared `AtRibbonGroups` component (`components/ribbon/groups.rs`) is the framework piece that owns the cascade: a tab hands it a `Vec`, it runs `use_ribbon_cascade` **once** for the strip, renders each group at its resolved state, and moves overflowed groups into a trailing **"More" menu** (an upward `position: absolute` dropdown — confirmed working in Blitz — rendering the overflowed groups in Full form). Group widths are **declared, not Blitz-measured** (per-element measurement is unreliable): the pure `estimate_group_metrics(priority, buttons, has_label)` derives full/condensed widths from the touch-button count (+2 tests). The **Layout tab** is migrated as the first real consumer — its four groups (Orientation/Margins/Size/Columns, priority descending so Columns overflows first) now flow through `AtRibbonGroups`, driven live off the editor's measured viewport width. New `LUCIDE_MORE_HORIZONTAL` icon + `ribbon-overflow-aria` string. **All tabs migrated + R-13e ✅ 2026-07-06** — the **Write**, **Insert**, **Publish**, and **Table** tabs now build `RibbonGroupSpec` lists through `AtRibbonGroups` too, so every tab collapses/overflows by priority (the group-helper fns in `editor_ribbon_format`/`editor_ribbon_color` return `RibbonGroupSpec` with a threaded priority; each tab declares a descending-importance scheme — core editing controls stay full longest, wide colour-swatch groups overflow first). Publish's ribbon content split to `editor_ribbon_publish.rs` (dropping the baselined `editor_publish.rs` 315 → 236, off the ceiling backlog) and the Table tab's `delete_current_table` to `editor_ribbon_table_delete.rs`. **R-13e ✅** — `AtRibbonGroup` exposes its resolved `GroupCollapse` to descendants as a *signal* context, and `AtRibbonSelect` reads it to shrink (`RIBBON_SELECT_WIDTH_PX` → `RIBBON_SELECT_WIDTH_CONDENSED_PX`) when its group is condensed; a signal, not a plain value, so prop-memoised selects still re-size reactively on resize. The overflow menu also auto-closes when a widen removes the overflow. **Remaining tail:** true outside-click-to-dismiss for the More menu — it needs the menu hosted in a shared **window-level overlay** (like the editor-root overlay the spell panel uses) so a full-viewport backdrop can span the viewport; a backdrop rendered in-place can't (`position: fixed` collapses to `absolute` in stylo_taffy). Toggle-close + auto-close-on-widen ship today; `TODO(ribbon)` marks the overlay-host follow-up. **M3 is otherwise complete.** | L | | 4a.2 | Spec 04 M5 | Layout/References/Review ribbon tabs + ~~`selected_object` contextual-tab signal~~ (✅ **Done 2026-07-06** — new `editing/selected_object.rs`: pure `selected_object(&CursorState) -> SelectedObject` (Table when the focus path descends through a cell). `editor_ribbon_table::use_ribbon_tabs` derives it via `use_memo`, appends an amber **Table** contextual tab while the caret is in a table, and resets the active tab to Write when the caret leaves (so no orphaned selection). The tab's **Delete Table** action is backed by a new `delete_block` model mutation (`loro_mutation/block_edit.rs`, split from `block.rs` to hold the ceiling), disabled when the table is the document's only block; the caret re-homes to the neighbouring block. New `LUCIDE_TRASH_2` icon. Tests: `selected_object` (5), `ribbon_tabs` (3), `delete_block` (3). **Structural row/column ops ✅ Done 2026-07-06** — the Table tab's "Rows & Columns" group inserts/deletes rows and columns via new `loro_mutation/table_ops.rs` mutations (`insert_table_row`/`delete_table_row`/`insert_table_column`/`delete_table_column` + `table_grid_dims`): they rewrite the serde skeleton **and** minimally patch the flat `KEY_TABLE_CELLS` list (surviving cells keep their live CRDT text), scoped to simple grids (no spans/head/foot — else typed `UnsupportedTableStructure`). The caret re-homes to its shifted cell (pure `caret_flat_after` in `editor_ribbon_table_ops.rs`); delete buttons disable at 1 row/col; 4 app-custom table-op glyphs. Tests: 12 round-trip (`table_structural_ops.rs`) + 4 caret-math. **Insert above/below + left/right ✅ Done 2026-07-06** — the insert ops are now split into four caret-relative variants (`TableOp::{InsertRowAbove,InsertRowBelow,InsertColumnLeft,InsertColumnRight}`): above/left insert at the caret's own row/col index, below/right at index+1, and `caret_flat_after` re-homes the caret accordingly (above shifts it down a row, left shifts it one column right). 2 app-custom glyphs (`AT_TABLE_ROW_INSERT_ABOVE`, `AT_TABLE_COL_INSERT_LEFT`); 2 new caret-math tests. **Paragraph alignment ✅ Done 2026-07-06** — the Write tab gains an Alignment group (left/centre/right/justify) driven by new path-aware `set_block_alignment_at`/`get_block_alignment_at` (`loro_mutation/align.rs`), so alignment works in table cells and note bodies too. `align.rs` handles every paragraph shape: a plain `para` is upgraded to `styled_para` so props survive the read path, `styled_para` uses `para_props`, and a `heading` uses its OOXML `jc` attr. The 6 inline-format buttons + the new alignment buttons were extracted to `editor_ribbon_format.rs` (dropping `editor_ribbon.rs` 300 → 225). 5 alignment tests (`block_alignment.rs`). **Font-size grow/shrink ✅ Done 2026-07-06** — a Write-tab Font group steps the selection's `MARK_FONT_SIZE_PT` up/down a fixed size ladder (`editor_font_size.rs`, path-aware via `mark_text_at`/`resolve_format_ranges`, so it works in cells and across multi-paragraph selections); pure ladder + end-to-end mark tests (5). 2 app-custom "A±" glyphs. **Text colour ✅ Done 2026-07-06** — a Write-tab Font-colour group with an Automatic (clear) swatch + 6 preset colours applies `MARK_COLOR` (the `#RRGGBB` hex is the codec's own RGB form, so no extra encoding) across the selection, path-aware (`editor_text_color.rs`); coloured-square swatches render inside `AtRibbonIconButton`. 3 tests incl. round-trip into `CharProps.color`. **Highlight colour ✅ Done 2026-07-06** — a Write-tab Highlight group (None clear-swatch + 5 preset colours: Yellow/Green/Cyan/Magenta/Red) writes `MARK_HIGHLIGHT_COLOR` as a `HighlightColor` variant name (or `Null` to clear) across the selection, path-aware (`editor_highlight_color.rs`); the swatch fills are the RGB each variant renders as (`resolve::map_highlight_color`). The duplicated font-colour/highlight swatch UI was unified into a generic `swatch_group(palette, apply_fn)` in `editor_ribbon_color.rs`. 3 tests incl. round-trip into `CharProps.highlight_color`. **Layout tab ✅ Started 2026-07-06** — a new non-contextual **Layout** tab (Write/Insert/**Layout**/Publish; contextual Table now at index 4) with a page-**orientation** toggle backed by new `set_document_orientation`/`document_is_landscape` model mutations (`loro_mutation/page.rs`): the layout engine reads the effective `page_size` directly, so the toggle swaps width↔height on every section + sets the orientation flag, and `apply_mutation_and_relayout` re-flows at the new size (verified the pipeline updates `page_width_px`). 4 round-trip tests (`page_orientation.rs`) + updated ribbon-tab tests; 2 app-custom page-rect glyphs. **Margin presets ✅ Done 2026-07-06** — the Layout tab's Margins group applies Normal/Narrow/Wide via new `set_document_margins`/`document_margins` (`page.rs`; sets top/bottom/left/right on every section, leaves header/footer/gutter); the active preset highlights via the pure `margin_matches` (½-pt tolerance). 3 model tests (`page_margins.rs`) + 5 preset-match tests; 3 app-custom page-inset glyphs (tooltip-disambiguated). **Page size ✅ Done 2026-07-06** — the Layout tab's Size group applies A4/US-Letter via new `set_document_page_size`/`document_page_size` (`page.rs`), **preserving each section's orientation** (choosing A4 while landscape gives A4 landscape); the active size highlights via the orientation-independent `page_size_matches`. 3 model tests (`page_size.rs`, incl. orientation preservation) + 4 preset-match tests. **Columns ✅ Done 2026-07-06** — the Layout tab's Columns group applies one/two/three via new `set_document_columns`/`document_column_count` (`page.rs`; count clamped ≥1, a new columns map gets a default 0.5in gap + no separator, an existing one keeps its gap/separator when the count changes); 5 model tests (`page_columns.rs`). The Layout tab is now Orientation + Margins + Size + Columns. **References tab ✅ 2026-07-07** — a new non-contextual **References** tab (Write/Insert/Layout/**References**/Publish; contextual Table now at index 5) generating a **table of contents** from the document's headings. The pure, format-neutral builders live in `loki-doc-model` (`content/toc.rs`): `heading_outline(sections, max_depth)` collects `(level, label)` for every `Block::Heading` within depth (default 3), `inline_plain_text` flattens a heading's inlines to its label, and `build_toc` produces a `TableOfContentsBlock` whose cached `body` is level-indented entry paragraphs (page numbers are omitted — they need the paginated layout — matching a freshly-inserted Word TOC field). The CRDT mutations (`loro_mutation/toc.rs`): `insert_table_of_contents` builds a TOC from the live headings and inserts it after the caret's block; `refresh_table_of_contents` rebuilds an existing TOC's snapshot in place (the "update field" action, a guarded no-op on a non-TOC block); `first_toc_block_index` finds the TOC to enable/refresh. A `Block::TableOfContents` round-trips through the bridge as an opaque JSON snapshot, so both are undoable. **Root-cause layout fix:** `loki-layout`'s `flow_block` silently dropped `TableOfContents`/`Index` blocks via its `_ => {}` catch-all, so an inserted *or imported* TOC was invisible — now both flow their cached body (a new `flow_blocks` helper the merged Div/Figure arms also use, so `flow.rs` held at its 1953 baseline). The **References** tab (`editor_ribbon_references.rs`) offers **Insert** + **Update** (Update disabled with no TOC); 2 app-custom glyphs (`AT_TOC_INSERT`/`AT_TOC_UPDATE`); the tab-index shift updated `ribbon_tabs`/`CONTEXTUAL_TAB_INDEX`/the tab-content match. 12 model tests (`content::toc` 7, `loro_mutation::toc` 5) + 1 layout regression test + updated ribbon-tab tests; 5 i18n keys. **Review tab — model foundation ✅ 2026-07-07** — the first slice of track changes. A **live** tracked-change mark (distinct from the dormant, round-trip-only opaque `TrackedChange`): `style/props/revision.rs` defines `RevisionKind { Insertion, Deletion }` + `RevisionMark { kind, author, date, id }` with a `US`-delimited packed string codec (no serde/chrono on the hot path). It rides a run as `CharProps::revision` (run-level, **not** style-inherited — omitted from `merged_with_parent`), so a tracked run is an `Inline::StyledRun` whose `direct_props.revision` is set — the same marks mechanism as highlight colour, keeping the paragraph live-editable. Wired through the CRDT bridge (`MARK_REVISION` in `CHAR_MARK_KEYS` + write/read), so a tracked run survives an edit cycle (round-trip tested). Pure, tested accept/reject transforms (`content/revision_ops.rs`): `accept_revisions`/`reject_revisions` over the whole block tree (recurse lists/tables/notes/quotes/TOC) — accept keeps insertions (clears the mark) and removes deletions, reject does the inverse; plus `has_revisions` and `Document::{accept_all_revisions,reject_all_revisions,has_tracked_changes}`. A `DocumentSettings.track_changes` flag (serde-default, back-compat) records whether new edits are tracked. 16 tests (revision codec 4, accept/reject 6, char_props 2 relocated, bridge round-trip + serde back-compat 2, +2). `char_props.rs` inline tests extracted to hold the ceiling. **Review tab — rendering ✅ 2026-07-07** — tracked changes are now visible. `loki-layout/src/revision_style.rs` colours a tracked run by its author (a deterministic 6-colour palette hashed off the author name) and decorates it by kind — insertion **underlined**, deletion **struck through** — applied to the run's `StyleSpan` in `char_props_to_style_span` (so it flows through the existing Parley decoration + brush path; the renderer needs no change). Because colour/decoration are derived from the mark at layout time, accepting/rejecting (which clears the mark) reverts the run with nothing stored to undo. 4 unit tests (`revision_style`: insertion underline, deletion strikethrough, no-op, author-colour determinism) + 1 layout regression (`tracked_runs_render_insertion_underline_and_deletion_strikethrough`); baselined `resolve.rs`/`lib.rs` held at baseline via a comment tightening + a redundant blank-line drop. **Review tab — editor records tracked insertions ✅ 2026-07-07** — typing now records tracked changes when the flag is on. New CRDT mutation `insert_text_tracked_at` (path-aware, so it works in cells/notes) inserts text **and** marks the range with `MARK_REVISION`. Crucially, `MARK_REVISION` is reconfigured `expand: None` in `configure_text_style` (unlike the `After` of formatting marks), so a revision covers exactly the changed range and never bleeds onto adjacent — possibly untracked — typing; consecutive tracked inserts by one author coalesce because their encoded mark value is identical. The editor's `handle_character_key` reads `Document::insertion_revision()` (a pure helper: `Some(Insertion by meta.creator)` when `DocumentSettings.track_changes` is on, else `None`) and routes typing through the tracked mutation accordingly — so a document with track-changes on shows typed text underlined in the author colour (rendering already wired). 3 tests: the pure `insertion_revision` decision, a CRDT round-trip proving the tracked insert marks only its range and does not leak onto a following plain insert, plus the existing bridge round-trip. **Review tab + durable toggle ✅ 2026-07-07** — track changes is now reachable and usable. **Root-cause fix:** `DocumentSettings` now round-trips through the Loro CRDT (`loro_bridge/settings.rs`, a JSON snapshot under `KEY_SETTINGS` like metadata/comments) — previously the bridge dropped settings, so the `track_changes` flag was wiped on the first relayout (which re-derives the doc from the CRDT). `set_track_changes(loro, on)` / `document_track_changes(loro)` flip and read the flag durably (undoable, survives relayout + save). A new non-contextual **Review** tab (Write/Insert/Layout/References/**Review**/Publish; contextual Table now at index 6) hosts a **Track Changes** toggle whose active state reflects the flag and whose click routes through `set_track_changes` + relayout. So the whole pipeline works end to end: toggle on → typed text records as a tracked insertion (`insert_text_tracked_at`) → renders underlined in the author colour. 4 tests (settings bridge set/get + preserve-others; full-document settings round-trip; +updated ribbon-tab tests); 1 app glyph (`AT_TRACK_CHANGES`); 3 i18n keys. **Review tab — accept/reject all ✅ 2026-07-07** — the review loop is closed: changes can be accepted or rejected. New CRDT mutation `accept_reject_all_revisions(loro, accept)` applies the accept/reject semantics **surgically** to the live Loro text (so it's one undoable step and the editor keeps its handle): it walks each top-level block's `to_delta()` for `MARK_REVISION` spans and, back-to-front, either clears the mark (`mark_utf8(range, …, Null)`) for a kept run (accepted insertion / rejected deletion) or deletes the text for a removed run — the CRDT analogue of the pure `revision_ops` transforms, returning the count resolved. The Review tab gains a **Changes** group with **Accept all** / **Reject all** buttons (disabled when `Document::has_tracked_changes()` is false, so they grey out once the document is clean). 4 CRDT tests (accept keeps-ins/removes-del + clears marks, reject inverse, no-op when clean, multi-block) + 2 app glyphs (`AT_CHANGE_ACCEPT`/`AT_CHANGE_REJECT`) + 3 i18n keys. *(Scope: top-level block text; revisions nested in table cells / note bodies are `TODO(review-nested)`.)* **Review tab — tracked deletions ✅ 2026-07-07** — track-changes recording is now complete: Backspace/Delete strike text through instead of removing it. The pure `delete_action(existing, tracking)` (Word semantics: tracking off ⇒ hard delete; on ⇒ hard-delete the author's own insertion, skip an already-struck deletion, else mark struck) drives the CRDT mutation `tracked_grapheme_delete`, which reads the target grapheme's `MARK_REVISION` (via `get_mark_at_path`) and applies the decision — deleting the text, marking it a deletion, or no-op — returning the [`DeleteAction`] so the editor places the caret (Backspace lands before the grapheme in every case; forward-Delete keeps the caret on a hard delete but steps past a struck grapheme). `Document::deletion_revision()` supplies the author-attributed deletion mark (its `Some`/`None` is the tracking flag). `handle_backspace_key`'s grapheme path and `handle_delete_key` both route through it. 5 tests (`delete_action` truth table, `deletion_revision` flag, + 3 CRDT: strike-normal, hard-delete-off, remove-own-insertion/skip-already-struck). *(Scope: single-grapheme Backspace/Delete; a **selection** delete under track changes still hard-deletes — `TODO(review-selection-delete)` — as does Backspace at a paragraph start, since whole-paragraph-mark deletion isn't modelled.)* **OOXML `w:ins`/`w:del` import+export ✅ 2026-07-07** — tracked changes now round-trip through DOCX, so they survive save/open in Word. **Import:** `w:ins`/`w:del` were already recognised structurally but dropped their semantics; now `parse_tracked_runs` reads the `w:author`/`w:date`/`w:id` attributes into a `DocxTrackedChange`, `parse_run` also reads `w:delText` (deleted-run text, previously discarded — a zero-cost widening of the `w:t` match), and the mapper attaches a `RevisionMark { kind, author, date, id }` to every wrapped run's `CharProps.revision` (deletions are kept, struck-through, not dropped). **Export:** `write_styled_run` wraps a run carrying `revision` in `w:ins`/`w:del` with those attributes, and its text emits as `w:delText` for a deletion (`write/revision.rs`). 1 DOCX round-trip test (insertion + deletion, author + date + text all survive). The mapper `inline.rs` test module was extracted (`inline_tests.rs`) and the two new intermediate structs moved to `model/revision.rs` to hold the three baselined files at baseline. **ODF `text:tracked-changes` import+export ✅ 2026-07-07** — tracked changes now round-trip through ODT too, so they survive save/open in LibreOffice. ODF splits a change between the document-leading `text:tracked-changes` table (one `text:changed-region` per change: `text:insertion`/`text:deletion` + `office:change-info` with `dc:creator`/`dc:date`; a deletion stows its removed `text:p` text) and body milestones keyed by `text:change-id` (an insertion is bracketed by `text:change-start`/`text:change-end`; a deletion is a single `text:change` point). **Import:** a new `reader/revisions.rs` parses the region table into `OdfChangedRegion`s (carried as an `OdfBodyChild::TrackedChanges`); `reader/inlines.rs` captures the `text:change-*` milestones as new `OdfParagraphChild` variants; the mapper (`mapper/document/inlines.rs`) resolves each milestone against the region map threaded through `OdfMappingContext` — a bracketed range becomes an insertion-marked run, a deletion point re-materialises the region's removed text as a struck run. **Export:** a new `write/revisions.rs` collects a `Changes` table during body rendering (flushed right after `` opens) and `write_styled_run` emits the milestones for a `revision`-carrying run (date written verbatim so RFC-3339 round-trips exactly). 1 ODT round-trip test (insertion + deletion, author + date + text all survive), plus a verified-conformant XML dump. Ceiling held by trimming doc comments in the at-ceiling `mapper/document/mod.rs` and by making the shared `wrap_span`/`plain_text` writers `pub(super)` rather than duplicating them. **Selection tracked deletion ✅ 2026-07-07** — deleting a **selection** under track changes now strikes it through instead of hard-deleting. New CRDT mutation `tracked_delete_selection_at` (`loro_mutation/selection.rs`): with a deletion mark it strikes each block's selected slice via `strike_range` — walking `to_delta()` and applying `delete_action` per run segment (the author's own tracked insertions are hard-deleted / un-typed, already-struck text is skipped, everything else is marked struck) — and **preserves the paragraph marks between selected blocks** (no merge, unlike the untracked path which merges); with `None` it delegates to the existing hard-deleting `delete_selection_at` (the two now share a `normalize_selection` front-end). The editor's single selection-delete choke point `delete_selection_in_doc` gained a deletion-mark parameter and a `deletion_mark(doc_state)` helper, so Backspace/Delete/Enter-over-selection **and** replace-typing all strike under tracking (Word inserts the newly typed run before the struck old text). 5 CRDT tests (`loro_tracked_selection_tests.rs`: single-block strike, own-insertion hard-delete, already-struck skip, multi-block paragraph-marks-preserved, `None` hard-delete+merge). Ceiling held by trimming `editor_keydown_text.rs` comments. **Per-change accept/reject ✅ 2026-07-08** — the Review tab's Changes group now has **Accept / Reject** buttons (circle-check / circle-x glyphs, distinct from the plain check/cross Accept-all/Reject-all) that resolve just the change **at the caret**. New model fns (`loro_mutation/revision.rs`): `accept_reject_revision_at(loro, path, byte_offset, accept)` finds the contiguous `MARK_REVISION` span at the caret (`span_at` — the span containing the offset, else the one ending at it) and resolves it via the shared `resolve_span` (delete a removed run's text, clear a kept run's mark), returning the collapsed caret offset (change start on removal, else unchanged) or `None` when the caret isn't on a change; `revision_at(loro, path, byte_offset)` is the read-only query driving the buttons' enabled state. `resolve_text` (accept/reject-all) was refactored to share `revision_spans` + `resolve_span`. The ribbon handler `accept_reject_at_caret` (`editor_ribbon_review.rs`) reads the caret from `cursor_state`, applies the mutation, relayouts, and repositions the caret; the buttons enable only when `change_at_caret` (via `revision_at`) is true, recomputing as the caret moves. 7 CRDT tests (`loro_per_change_revision_tests.rs`: accept/reject × insertion/deletion, no-op off a change, `revision_at` true/false, only-the-caret-change-resolved); 2 app glyphs + 2 i18n keys. **Nested-container resolution ✅ 2026-07-08** — accept/reject-all now reaches revisions **inside table cells and note bodies**, not just top-level paragraphs. A new `loro_mutation/text_containers.rs` (`collect_all_text_containers`) walks every section's block list and recursively descends each block's `KEY_TABLE_CELLS` / `KEY_NOTES` containers, returning every `LoroText` content container; `accept_reject_all_revisions` now sweeps that full set instead of iterating top-level block indices (which skipped tables via `TextNotFound`). This closes the latent gap where the Accept-all / Reject-all buttons enabled on a nested change (`has_tracked_changes` already recurses) but did nothing. The per-change ops were already path-aware, so they resolve nested changes too. `section_blocks_list` was exposed `pub(super)`; the collector lives in its own module to hold `nested.rs` under the ceiling. 3 CRDT tests (`loro_nested_revision_tests.rs`: accept keeps / reject removes a table-cell change, accept a footnote-body change — each asserting the doc ends clean). **Paragraph-mark tracked deletion ✅ 2026-07-08** — the last Review tail. The paragraph mark (¶) is modelled by a paragraph's `direct_char_props` (the OOXML `w:pPr/w:rPr` slot), so a tracked ¶-deletion is simply a `Deletion` on `direct_char_props.revision` — no new model type. **Round-trip:** the bridge previously dropped block-level char-props `revision`; `map_char_props_to_map` / `reconstruct_char_props_from_map` now write/read it under a new `PROP_REVISION` key, so it survives the CRDT. **Record:** new `loro_mutation/para_mark.rs::set_para_mark_deletion` marks the previous paragraph's ¶ (upgrading a plain `para`→`styled_para` like alignment does), declining non-paragraphs so the caller hard-merges; the editor's Backspace-at-start (extracted to `editor_keydown_backspace.rs` to hold the ceiling) routes a top-level paragraph start through it under tracking. **Resolve:** `accept_reject_all_revisions` now also sweeps para-marks (`para_mark::resolve_para_marks`, recursing into cells/notes) — accept removes the ¶ (successor merges via `merge_block_in_list`), reject clears; the pure transforms merge too (`content/para_mark_merge.rs`, shared by `resolve_blocks`). `has_revisions` detects a para-mark so the Accept/Reject buttons enable. 8 CRDT/model tests (`loro_para_mark_revision_tests.rs`: round-trip, accept-merges, reject-splits, pure transforms, set+upgrade, heading-declines, trailing-mark, post-merge editability). *(Deferred: rendering a struck ¶ glyph; nested-container recording — `TODO(review-para-mark-nested)`; per-change resolution of a para mark.)* **The Review tab (track changes) is now feature-complete for the editor path.** **DOCX para-mark round-trip ✅ 2026-07-08** — a tracked ¶ deletion now survives save/open in Word. **Export:** `write/revision.rs::write_mark_del` emits the self-closing ``/`` inside the paragraph mark's `w:pPr/w:rPr` (a new shared `write_rev_element` backs both it and the run-wrapping `open`). **Import:** `parse_rpr_element` recognises a `w:del`/`w:ins` child of the pPr's rPr via `reader/runs.rs::parse_mark_revision` into a new `DocxMarkRevision` on `DocxRPr`, which `map_rpr` maps to `CharProps.revision`. 1 round-trip test (`paragraph_mark_deletion_round_trips`). Ceiling held by extracting `reader/document.rs`'s inline tests to `document_tests.rs` and tightening a few doc comments in the at-ceiling `mapper/props.rs` / `model/paragraph.rs`. **Nested-container para-mark recording ✅ 2026-07-08** — Backspace-at-start inside a table cell / note body now records a tracked ¶ deletion too (previously only top-level). New path-aware `set_para_mark_deletion_at` (both it and the index-based `set_para_mark_deletion` share `write_para_mark`); the editor's `record_para_mark_deletion` computes the previous block's path via `focus.sibling_block(-1, 0)` and a `has_previous_sibling` guard (leaf index > 0), so it works at any nesting. The accept/reject sweep already recursed into cells/notes, so resolution needed no change. 1 CRDT test (`records_and_accepts_a_para_mark_inside_a_table_cell`). **Per-change para-mark resolution ✅ 2026-07-08** — the Review tab's per-change Accept/Reject buttons now resolve a paragraph-mark deletion too, not just text runs. New model fns `para_mark_at` (enable query) and `accept_reject_para_mark_at` (accept merges the successor into the caret's paragraph; reject clears the mark; returns the paragraph-end caret offset). The ribbon handler `accept_reject_at_caret` tries the text-span change first, then falls back to the para-mark; `change_at_caret` ORs in `para_mark_at`. 4 CRDT tests (`para_mark_at` detection, per-change accept-merges, reject-clears, no-op without a mark). **Remaining polish:** ODF para-mark export and struck-¶ rendering. | L | -| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **ODT cell-shading export ✅ 2026-07-08** — the first ODF-side increment. ODF has no conditional-region concept: it bakes table shading into **per-cell** automatic styles (LibreOffice's on-disk model), and the ODT writer previously emitted `` with no formatting at all. `AutoStyles::cell_style` (`odt/write/auto.rs`) now emits a deduplicated automatic `` carrying `fo:background-color` (`TC{n}` names, co-located `emit_cell_properties`), referenced by `table:style-name` on each shaded cell in `write/tables.rs`. ODT **import** of `fo:background-color` already existed (`map_cell_props` reads it into `CellProps.background_color`), so a shaded cell now round-trips through ODT with no import change. 3 tests: `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer unit) + `cell_background_round_trips_via_table_cell_style` (end-to-end ODT export→import); full loki-odf suite (incl. schema validation) green. **ODT banding resolution on export ✅ 2026-07-08** — bridges the two formats' models: a table carrying only a `"style"` reference + `"tbllook"` (e.g. a DOCX-imported banded table) now exports its bands to ODT as concrete per-cell shading. `write/tables.rs` flattens the rows, assigns each cell its grid column (`assign_grid_columns` — a coverage-grid mirror of the layout's `assign_cell_columns`, honouring `col_span`/`row_span` merges), then in a two-phase pass computes each cell's effective background = its direct shading **else** `resolve_cell_shading(style, look, row, col, rows, cols)` (the very doc-model resolver the layout paints with) and bakes it into the per-cell `table-cell` automatic style (phase 1 resolves under an immutable catalog borrow, phase 2 mints styles under `&mut cx.auto` — avoiding a borrow conflict). The style catalog reaches the writer via a `Cx.table_styles` clone (`content.rs`; the header/footer `Cx` in `styles.rs` uses an empty map). `AutoStyles::cell_style` was generalised to take the resolved `Option<&DocumentColor>` rather than `&CellProps`. 1 round-trip test (`table_style_banding_resolves_into_per_cell_shading_on_odt_export`: a firstRow-banded style with no direct shading → header cells return shaded, body cells not). **Remaining 4a.3:** ODT `table:style-name` (table-level width/align) write; cell **borders**/padding export; `w:cnfStyle`; conditional character formatting; and the editing UI. Plus the Page-family tail and the ODF table default-style import (blocked on ODT table-style import). | L | +| 4a.3 | Spec 05 | **Page** style family (`page_styles` catalog per ADR-0012) and **Table** family (`TableProps` conditional/banding regions); character-style editing form; per-family non-paragraph `Default` sources; Compact-tree breadcrumb (M7). **Character-family `Default` source ✅ 2026-07-06** — the first of the per-family non-paragraph `Default` sources (ADR-0012 Decision 1). New `StyleCatalog::default_character_style` (serde-default, so it round-trips through the Loro bridge and is back-compatible); `resolve_char_chain` now falls through to it (`first_in_char_chain`, cycle/depth-guarded) so a standalone character style resolves the document's `docDefaults` run defaults as `Provenance::Default` instead of `FormatDefault` — the char inspector was previously **blind** to docDefaults. The OOXML importer synthesises a `__DocDefaultChar` character style from `w:rPrDefault` and points the default at it; the character browser hides `__`-prefixed synthetic styles, and both the DOCX and ODT writers skip them (they belong in `docDefaults`/`default-style`, not as named `w:style`/`style:style` — also fixes a latent `__DocDefault` paragraph leak). 4 model tests + 3 mapper tests; full OOXML/ODF/round-trip suites green. **Character-style editing form ✅ 2026-07-06** — the character family is now editable, not just inspectable (Spec 05 M6). Selecting a character style seeds an editable `StyleDraft` (`char_style_to_draft`) that a new `char_form.rs` binds — reusing the paragraph form's shared inputs (`field_row`/`iu_buttons`/`font_picker`/`weight_selector`, all of which already bind a `Signal>`) for name/based-on/font-family/weight/size/italic/underline. Apply commits a `CharacterStyle` to the catalog through Loro (`commit_char_style_to_loro`, persisted via the existing `write_document_styles` bridge, undoable) and relays out, **cycle-guarded** by new model helpers `char_ancestors`/`char_reparent_cycles` (the character analogue of the paragraph re-parent guard). The editable form renders alongside the read-only provenance inspector (inspector shows *where* inherited values come from, form edits the locals — the Spec 05 §6 inspector+edit pairing). 1 model test (`character_reparent_cycle_is_detected`); `editor_inner` held at its 803 baseline. **Compact-tree breadcrumb ✅ 2026-07-06 (M7)** — at Compact the paragraph inheritance tree's full indented list degrades to a **breadcrumb + drill-down** (Spec 05 §7/§11): the breadcrumb is the root→selected path (new model `para_breadcrumb` = `para_ancestors` reversed, cycle-guarded), each hop clickable to jump up; below it the selected style's direct **substyles** (`para_children`) are clickable to descend. `body::left_column` renders it via a new `tree_nav.rs` when `posture.stack` (Compact) and keeps the indented tree at Expanded/Medium. Navigation loads the target's draft exactly as the indented tree does. 1 model test (`breadcrumb_is_root_first_including_self`) + the existing posture tests. **Table-family resolver + `Default` source ✅ 2026-07-06** — the table family had single-parent inheritance in the model but **no provenance resolver** (only para/char existed). Added the table analogue: `resolve_table_chain` (Local/Inherited/**Default**/FormatDefault via `first_in_table_chain` + the new `default_table_style` catalog field), plus `table_ancestors`/`table_reparent_cycles`, in a new `resolve_table.rs` module (the `Resolved` constructors are now `pub(crate)` so the split compiles; keeps `resolve.rs` at 299, under the ceiling). The OOXML importer records `default_table_style` from the table style flagged `w:default="1"` (e.g. `TableNormal`). 3 model tests + 2 mapper tests. *(Lists are a **non-inheriting** family per ADR-0012 Decision 2 — no parent chain, so `Default` doesn't apply; they resolve Local/FormatDefault only. Table-style **export** of the default flag is deferred with the wider table-style writer, which isn't built yet.)* **ODF character-default import symmetry ✅ 2026-07-06** — the ODF half of the character `Default` source: the ODT mapper now synthesises a `__DefaultChar` character style from `style:default-style style:family="text"` and points `default_character_style` at it (the ODF analogue of OOXML's `__DocDefaultChar`; the ODT writer already skips `__`-prefixed synthetics). 1 mapper test incl. an end-to-end `Provenance::Default` resolution. *(The ODF table default is not wired: `OdfDefaultStyle` carries no table props and the ODT mapper does not import table styles at all yet — noted for the wider table-style import.)* The mapper's inline test module was extracted to `styles_tests.rs` (`#[path]` idiom) to hold the 300-line ceiling (358 → 148 production). **Page style family — started ✅ 2026-07-06** — the model foundation for ADR-0012 Decision 2's page family. New `PageStyle` type (`style/page_style.rs`): a named, **non-inheriting** entry (no `parent`) wrapping the existing rich `PageLayout` (size/margins/orientation/columns + header/footer master + page numbering), and a `page_styles: IndexMap` catalog field (serde-default, round-trips through the Loro-bridge catalog JSON, back-compatible). The format-neutral **import-mapping core** is pure + tested: `derive_page_styles(sections)` collapses sections with an identical `PageLayout` into one page style (named `PageStyleN` in first-seen order, since OOXML has no page-style name to carry), and `section_page_style_ids(sections)` gives the per-section id list — the inverse the DOCX section-export (`sectPr`) needs. 7 model tests (`page_style_tests.rs`); no resolver needed (a non-inheriting family is a chain of length one — the inspector shows only Local/FormatDefault, per ADR-0012). **Read-only page panel ✅ 2026-07-06** — the page family is now visible in the style panel (Spec 05 §9), mirroring the read-only list family. A **Page styles** list in the left column (`page_browser.rs`) + a read-only **geometry inspector** column (`family_inspector` page column) showing size / orientation / margins / columns. The panel **derives page styles on demand** from the live document's sections (`panel_data::page_data` → `derive_page_styles`) rather than reading the stored catalog field: the section layouts are the source of truth (the Layout ribbon mutates them directly), so deriving each render keeps the panel from **drifting** — the root-cause-correct choice over a stored-but-stale copy. Pure, tested inspector rows (`style_page_inspector::page_inspector_rows`, value-baked like the list inspector: named sizes, uniform-margin collapse; 4 tests). New `editing_page_style` selection signal (`editor_inner` held at 803 via comment tightening); 5 i18n keys. **Per-page-style edit mutation ✅ 2026-07-06** — the write-back primitive for LibreOffice-style per-page-style editing: `set_page_style_geometry(loro, section_indices, &PageLayout)` (`loro_mutation/page_style.rs`) applies a layout's size / orientation / margins / columns to **only the given sections** — the sections that belong to one page style (the panel derives the indices from `section_page_style_ids`) — leaving the other page styles, and each section's headers/footers/gutter/page-numbering, untouched. This is the per-style analogue of the document-wide `set_document_*` setters. Chosen over a stored `Section.page_style` reference + renderer refactor because page styles are already derived by layout-equality and an edit keeps a style's sections in sync, so index-targeting is stable without touching the fragile CRDT bridge or the layout engine. 3 integration tests (`page_style_geometry.rs`: only-its-sections, margins+columns, out-of-range skip). **Editable page form ✅ 2026-07-06** — the page panel is now editable per-page-style (LibreOffice model). Selecting a page style shows a preset form (`page_form.rs`) — Orientation / Size / Margins / Columns buttons, matching the Layout ribbon — that applies to **only that page style's sections**. The pure, tested transform `apply_preset(&PageLayout, PagePreset) -> PageLayout` builds the edited layout (orientation/size preserve the other axis; margins keep header/footer/gutter; columns keep the gap); each button computes the target section indices via `panel_data::page_edit_target` (derived on demand, always live) and writes through `set_page_style_geometry`, then relays out. 4 `apply_preset` tests. So editing "PageStyle1" changes all its pages and leaves "PageStyle2" alone. **Stored section→page-style reference ✅ 2026-07-06** — the model refinement toward true LibreOffice-style named page styles: `Section.page_style: Option` names the section's page style (persisted through the Loro bridge under `KEY_PAGE_STYLE_REF`), and `Document::assign_page_styles()` normalises a loaded document — dedups sections by layout into catalogued page styles and stores the refs, **idempotently** (a section that already names a style, e.g. a user rename or an ODF `style:master-page`, is preserved). Wired at `load_document` so every opened document gets first-class, stored, renamable page styles. 4 model tests (`page_style_model.rs`: dedup, idempotence/name-preservation, bridge round-trip, unnamed→None); the `Section` field addition rippled to ~15 test literals + 2 mapper/flow literals (offset the two baselined files back to baseline). **Rename UI + panel-reads-stored migration ✅ 2026-07-06** — the panel now reads the **stored** `section.page_style` refs instead of deriving by layout-equality, and page styles are renamable. `panel_data::stored_page_styles` groups sections by their stored ref (first-seen order) and reads the representative geometry from the first referencing section (`section.layout`, the renderer's truth) — so a page style is a **stable, renamable identity** while its geometry stays drift-free even when the Layout ribbon edits `section.layout` document-wide. A new `rename_page_style(loro, old, new)` mutation (`loro_mutation/page_style.rs`) renames the catalog key **and** every referencing section's stored ref atomically, keeping the `PageStyle.id` in sync and no-opping on name conflict / missing source. The page form (`page_form.rs`) grows a `PageRenameField` component (`page_rename.rs`, ADR-0013 — owns its draft signal, keyed by name to reseed on reselection) whose Rename button commits through the mutation, relays out, and re-selects the style under its new name. 2 rename integration tests (catalog+section refs updated; conflict/missing no-op) + the existing geometry tests; 2 i18n keys. This resolves the earlier drift caveat: identity comes from the stored ref, geometry from the live section. **ODT native page-style naming + importer population ✅ 2026-07-07** — the ODF-native round-trip for named page styles (ADR-0012 Decision 2). **Export:** a new `odt/write/page_styles.rs` resolves each section's `style:master-page` / `style:page-layout` names from the stored `section.page_style` id (sanitised to a valid XML `NCName` via `xml::sanitize_ncname`), so a named — or renamed — page style is written out under its real name instead of the old positional `MP{idx}`. Sections sharing a page style collapse to **one** master page (the first referencing section's layout is the representative geometry — the same choice the panel makes), matching LibreOffice's shared-master model; sections without a stored ref keep the positional fallback, so pre-page-style documents export byte-for-byte as before. Both `content.xml` (the `style:master-page-name` reference) and `styles.xml` (the master-page + page-layout definitions) read from the one resolver so the two always agree. **Import:** the ODT mapper now sets `section.page_style` from the master-page name each section uses and registers those names as first-class `page_styles` catalog entries (with `display_name`), so an opened ODT shows its real page-style names in the panel and they survive a re-export. 5 naming unit tests (`page_styles_tests.rs`: stored-id→master, shared-master dedup, positional fallback, NCName sanitisation, empty-doc) + 1 export→import round-trip (`odt_export_round_trip::named_page_styles_round_trip_as_master_pages`). **Master-page `style:display-name` round-trip ✅ 2026-07-07** — the page family's last tail item. `OdfMasterPage` gained a `display_name` field; the ODT reader parses `style:display-name` off both the container and self-closing `` forms, and the mapper carries it onto the `PageStyle` (only when distinct from the id — a redundant one stays `None`, and fabricating `Some(id)` is no longer done, so a later rename isn't shadowed). Export writes `style:display-name` on the master page when the catalog gives the style a name distinct from the emitted `NCName`. So a page style with a spaced/human name (id `WideBody`, display "Wide Body") round-trips both halves. +1 export unit test + display-name assertions in the round-trip test; the self-closing-master reader branch was refactored through a new `OdfMasterPage::header_footer_less` constructor to hold the `reader/styles.rs` ceiling. **Page family complete** — OOXML has no named page style (DOCX sections already export as `w:sectPr` per page style, and `assign_page_styles` names them `PageStyleN` on import — nothing further to wire). **Table-style reference — foundation ✅ 2026-07-08** — the prerequisite for table banding/conditional formatting: a `Block::Table` now **references its named style** (OOXML `w:tblStyle` / ODF `table:style-name`), which was previously dropped on import (the DOCX reader parsed `w:tblStyle` but the mapper never propagated it, and `Table` had no style field). Rather than add a `style_id` field to `Table` — an ~18-site struct-literal ripple across 8 crates — the reference is stored in the table's `NodeAttr` `"style"` key (the convention a `Block::Heading` already uses), read via `Table::style_name()` / written via `set_style_name()`. It round-trips through the Loro bridge for free (the bridge serialises the table skeleton incl. node attrs) and through DOCX (`map_table` carries it; the writer emits `w:tblStyle` before `w:tblW`). 4 tests: 2 DOCX round-trip (`table_style_round_trip.rs`), 1 CRDT bridge, and the no-style case. Ceiling held by trimming comments in the at-baseline `mapper/table.rs` / `write/document.rs`. **Table-style banding/conditional model + resolver ✅ 2026-07-08** — the pure-logic layer under table banding. `TableStyle` gained a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a new `TableLook` struct models the `w:tblLook` region flags (custom `Default` = Word's `04A0`: header row + first column + row banding on). A new `style/table_banding.rs` provides `resolve_cell_shading(style, look, row, col, rows, cols) -> Option`: it walks a 13-entry precedence array (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table), computes horizontal/vertical band membership (index parity over the band-eligible rows/cols, honouring band size and header/footer/first-col exclusion), and resolves *per-property* — a higher-precedence region that defines no shading falls through to the next that does, with `TableProps::background_color` as the base fallback. All pure — no layout/render dependency, so it needs no visual verification. 12 unit tests + `default_table_look_matches_word_04a0`; the ~4 `TableStyle`/`TableProps` struct literals across the workspace updated for the new fields. **Table-style shading reaches the cell paint ✅ 2026-07-08** — the resolver is now wired into the flow engine. A new `loki-layout` `table_shading` module (`resolve_table_style` looks a table's `"style"` attr up in the style catalog; `cell_style_shading` calls `resolve_cell_shading` under Word's default `w:tblLook`) is consulted at the Pass-3b cell-paint seam in `flow.rs`: the painted cell background is now `cell.props.background_color.or(style banding)` — direct cell shading still wins, but a cell with none falls through to the table style's conditional/banding shading. The two duplicated paint branches (in-progress page vs. finished page) were unified into a single target-vec selection — a DRY simplification that offset the new logic and dropped `flow.rs` from 1953 → 1948 (baseline ratcheted). 1 end-to-end flow test (`table_style_banding_shades_the_header_row` — a styled 2×2 table with no direct shading paints exactly its 2 header cells) + 3 `table_shading` unit tests. `w:tblLook` is assumed default until import lands (`TODO(table-tbllook-import)`). **DOCX `w:tblStylePr` conditional-formatting import ✅ 2026-07-08** — real Word documents now carry their table-style banding into the model. The DOCX styles reader (`reader/styles.rs`) gained a small state machine over `w:type="table"` styles: band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`, scoped by an `in_tcpr` flag so `w:tblPr/w:shd` and `w:rPr/w:shd` don't leak in), and each `w:tblStylePr` region's cell shading (tracked by a `current_region` set on the element's `@w:type` and reset on its close) — collected into new `DocxTableStyleProps`/`DocxTblStylePr` model types on `DocxStyle`. The styles mapper (`mapper/styles.rs`) translates them: `map_table_region` maps the twelve OOXML region names to `TableRegion` (unknown names skipped), band sizes + base shading fill (via the existing `xml_util::resolve_shading`) into `TableProps`, and each shaded region into the `conditional` map (unshaded regions skipped). So a document using a built-in banded style (*List Table*/*Grid Table Accent*) imports its conditional shading and — through the layout wiring above, under the default `w:tblLook` — **paints banded rows/header end-to-end**. The `DocxStyle.table` field addition rippled to 7 test literals (mechanical `table: None`). 4 tests: `parses_table_style_banding` + `non_table_style_has_no_table_props` (reader), `table_style_conditional_formatting_maps` (mapper, incl. unknown-region + unshaded-region skipping), all suites green. **Per-table `w:tblLook` import ✅ 2026-07-08** — a table instance now carries its **own** active-region flags instead of assuming Word's default. The DOCX reader (`parse_tbl_look` in `reader/document.rs`) parses `w:tblLook` from either the explicit boolean attributes (`w:firstRow`/`w:lastRow`/`w:firstColumn`/`w:lastColumn`/`w:noHBand`/`w:noVBand`, the `no*Band` flags inverted into positive banding) or the legacy `w:val` hex bitmask (bit masks `0x0020`…`0x0400`), into a new `DocxTblLook` on `DocxTblPr`. A format-neutral codec on the doc-model `TableLook` (`encode_attr`/`decode_attr` — a six-char `0`/`1` string, keeping the OOXML bit layout out of the model) lets the mapper (new tiny `mapper/table_look.rs`) encode it into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`, and `Table::table_look_code`/`set_table_look_code` store it as an opaque string so `content` needn't depend on `style`). The flow engine reads it (`table_shading::table_look` decodes, defaulting on absent/malformed) and threads it into `cell_style_shading`, replacing the hard-coded `TableLook::default()` — so a table that disables banding or enables the last-row/last-column region renders with its real active regions. 8 tests: `parse_tbl_look_reads_the_legacy_val_bitmask` + `parse_tbl_look_prefers_explicit_attributes` (reader), `map_tbl_look` ×2 (mapper), `table_look_attr_round_trips` + `table_look_decode_rejects_malformed` (model codec), `table_look_reads_the_encoded_attr_or_defaults` + `tbl_look_with_first_row_off_suppresses_header_shading` + `table_look_disabling_first_row_suppresses_style_shading` (layout, incl. end-to-end flow). Ceilings held by trimming comments in the at-baseline `mapper/table.rs` (307) and `flow.rs` (1948). **DOCX table-style banding export ✅ 2026-07-08** — the export half, closing a full DOCX round-trip for banding. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"`: band sizes → `w:tblPr` (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`, skipped when absent), base whole-table shading → `w:tcPr/w:shd`, and each conditional region → `w:tblStylePr w:type="…"` with its own `w:tcPr/w:shd` (`region_ooxml` inverts the mapper's `map_table_region`; the non-exhaustive `TableRegion` match skips unknown future variants). It also writes the table instance's `w:tblLook` (both the explicit boolean attributes and the legacy `w:val` hex bitmask via `look_bitmask`) into its `w:tblPr` from the `"tbllook"` attr, after `w:tblW` per the schema. Wired via `write_styles_xml` (a 2-line call) and `write_table` (a 1-line call — `write_tbl_look` takes `Option<&str>` and no-ops on absent/malformed, keeping `write/document.rs` at its 1073 baseline). 5 tests: 4 writer unit tests (`writes_conditional_regions_and_band_sizes`, `a_style_without_bands_omits_tblpr`, `writes_tbl_look_attributes_and_bitmask`, `malformed_tbl_look_code_writes_nothing`) + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact through the catalog + instance attr). **ODT cell-shading export ✅ 2026-07-08** — the first ODF-side increment. ODF has no conditional-region concept: it bakes table shading into **per-cell** automatic styles (LibreOffice's on-disk model), and the ODT writer previously emitted `` with no formatting at all. `AutoStyles::cell_style` (`odt/write/auto.rs`) now emits a deduplicated automatic `` carrying `fo:background-color` (`TC{n}` names, co-located `emit_cell_properties`), referenced by `table:style-name` on each shaded cell in `write/tables.rs`. ODT **import** of `fo:background-color` already existed (`map_cell_props` reads it into `CellProps.background_color`), so a shaded cell now round-trips through ODT with no import change. 3 tests: `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer unit) + `cell_background_round_trips_via_table_cell_style` (end-to-end ODT export→import); full loki-odf suite (incl. schema validation) green. **ODT banding resolution on export ✅ 2026-07-08** — bridges the two formats' models: a table carrying only a `"style"` reference + `"tbllook"` (e.g. a DOCX-imported banded table) now exports its bands to ODT as concrete per-cell shading. `write/tables.rs` flattens the rows, assigns each cell its grid column (`assign_grid_columns` — a coverage-grid mirror of the layout's `assign_cell_columns`, honouring `col_span`/`row_span` merges), then in a two-phase pass computes each cell's effective background = its direct shading **else** `resolve_cell_shading(style, look, row, col, rows, cols)` (the very doc-model resolver the layout paints with) and bakes it into the per-cell `table-cell` automatic style (phase 1 resolves under an immutable catalog borrow, phase 2 mints styles under `&mut cx.auto` — avoiding a borrow conflict). The style catalog reaches the writer via a `Cx.table_styles` clone (`content.rs`; the header/footer `Cx` in `styles.rs` uses an empty map). `AutoStyles::cell_style` was generalised to take the resolved `Option<&DocumentColor>` rather than `&CellProps`. 1 round-trip test (`table_style_banding_resolves_into_per_cell_shading_on_odt_export`: a firstRow-banded style with no direct shading → header cells return shaded, body cells not). **ODT table-level `table:style-name` write + reference round-trip ✅ 2026-07-08** — the ODT analogue of the DOCX `w:tblStyle` reference. A new `write/table_style.rs` emits a named `` for each catalog table style (skipping `__`-prefixed synthetics) into `styles.xml`'s ``, carrying table-level geometry: `style:width` (from `TableProps::width` `Absolute`) / `style:rel-width` (`Percent`), `table:align` (`align_value`), and `fo:background-color`; `write/tables.rs` references it via `table:style-name` on the `` element. **Import** restores the reference in one line — `map_table` sets `Table::set_style_name` from `OdfTable.style_name` (which the reader already parsed) — so a table's named style survives an ODT round-trip; the `TableWidth`/`TableAlignment` matches carry a wildcard arm since both enums are `#[non_exhaustive]`. 5 tests: 4 writer unit (`emits_width_alignment_and_background`, `percent_width_uses_rel_width`, `a_style_with_no_geometry_omits_table_properties`, `synthetic_styles_are_skipped`) + `table_style_name_reference_round_trips` (end-to-end); full loki-odf suite incl. schema validation green. **Remaining 4a.3:** ODT **import** of the table-style *definition* back into the catalog (the reference survives, but width/align/bg are written-but-not-re-read into a `TableStyle` — needs the reader `parse_style_props` table-properties extraction + a `table_styles` mapper); cell **borders**/padding export; `w:cnfStyle`; conditional character formatting; and the editing UI.

Verified against the Word reference on ACID TC-DOCX-023 (margin-anchored image, text wrapping to its right). **Per-line precision:** lines beside the float are narrowed while lines below it reclaim the full column (two-pass `para_band` layout, shared with drop caps) — verified against the Word reference where the text below the image returns to full width. **Cross-paragraph wrap:** a float taller than its anchoring paragraph keeps wrapping the *following* paragraphs (tracked as `flow::float_impl::ActiveFloat`) until its bottom is cleared; bounded to a single page and to consecutive plain paragraphs (a table/list/rule or page break reserves the float's remaining height instead). **Limitations (gap #12):** the live-editor path keeps the uniform-narrow fallback; the tight wrap **contour** is approximated by the bounding box; true `behindDoc` overlap and absolute anchor positioning are not yet done. `TopAndBottom`/behind-text floats still stack as a block.

The layout already flows a cell's blocks through `flow_block`/`flow_table`, so the nested table lays out and clips to the cell box with no layout change.

Read via `Table::style_name()`. Tested by `table_style_round_trip.rs` (DOCX) + `table_style_reference_round_trips_through_the_bridge` (CRDT). **Banding/conditional model + resolver** (2026-07-08): `TableStyle` now carries a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions — first/last row/col, the four corners, the horizontal/vertical bands, plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a `TableLook` struct models the per-table `w:tblLook` flags (default `04A0`: header row + first column + row banding). A pure `resolve_cell_shading(style, look, row, col, rows, cols)` (`style/table_banding.rs`) returns the shading a style contributes to a cell, honouring OOXML precedence (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table) and resolving *per-property* (a higher region with no shading falls through), with the base table shading as the final fallback. 12 unit tests (banding parity, band size, header/first-col exclusion, corner-needs-both-flags, precedence ordering, out-of-range). **Rendered** (2026-07-08): the flow engine now **consults the table style** when painting cell backgrounds — a new `loki-layout` `table_shading` module (`resolve_table_style` looks the style up in the catalog by the table's `"style"` attr; `cell_style_shading` calls the resolver) layers style/banding shading **under** any direct `CellProps` shading at the Pass-3b cell-paint seam (`flow.rs`), so a table that references a banded style paints its header/banded cells with no direct cell shading needed. The active `w:tblLook` is not yet imported, so Word's default (`04A0`) is assumed for now (`TODO(table-tbllook-import)`). Tested by `table_style_banding_shades_the_header_row` (flow) + `table_shading` unit tests. **DOCX conditional-formatting import** (2026-07-08): the DOCX styles reader now parses a `w:type="table"` style's band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`), and each `w:tblStylePr` region's cell shading (`w:type` + `w:tcPr/w:shd`) into a new `DocxTableStyleProps`/`DocxTblStylePr` model; the styles mapper translates them into `TableStyle.table_props` (band sizes + base `background_color`) and the `conditional` region map (`map_table_region` maps the twelve OOXML region names; unknown or unshaded regions are skipped). So a real Word document that uses a built-in banded style (e.g. *List Table*/*Grid Table Accent*) now imports its conditional shading and — via the layout wiring above under the default `w:tblLook` — **paints banded rows/header end-to-end**.

Tested by `parse_tbl_look_*` (reader), `map_tbl_look` (mapper), `table_look_attr_round_trips` (model codec), and `table_look_disabling_first_row_suppresses_style_shading` (flow, end-to-end). **DOCX banding export** (2026-07-08): the export half now writes table-style banding, so it survives a full DOCX round-trip. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"` (band sizes → `w:tblPr`, base shading → `w:tcPr/w:shd`, each conditional region → `w:tblStylePr w:type="…"` with its `w:tcPr/w:shd`), and writes the table instance's `w:tblLook` (both explicit boolean attributes and the legacy `w:val` bitmask) into its `w:tblPr` from the `"tbllook"` attr.

Tested by `table_style_round_trip.rs` (DOCX) + `table_style_reference_round_trips_through_the_bridge` (CRDT). **Banding/conditional model + resolver** (2026-07-08): `TableStyle` now carries a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions — first/last row/col, the four corners, the horizontal/vertical bands, plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a `TableLook` struct models the per-table `w:tblLook` flags (default `04A0`: header row + first column + row banding). A pure `resolve_cell_shading(style, look, row, col, rows, cols)` (`style/table_banding.rs`) returns the shading a style contributes to a cell, honouring OOXML precedence (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table) and resolving *per-property* (a higher region with no shading falls through), with the base table shading as the final fallback. 12 unit tests (banding parity, band size, header/first-col exclusion, corner-needs-both-flags, precedence ordering, out-of-range). **Rendered** (2026-07-08): the flow engine now **consults the table style** when painting cell backgrounds — a new `loki-layout` `table_shading` module (`resolve_table_style` looks the style up in the catalog by the table's `"style"` attr; `cell_style_shading` calls the resolver) layers style/banding shading **under** any direct `CellProps` shading at the Pass-3b cell-paint seam (`flow.rs`), so a table that references a banded style paints its header/banded cells with no direct cell shading needed. The active `w:tblLook` is not yet imported, so Word's default (`04A0`) is assumed for now (`TODO(table-tbllook-import)`). Tested by `table_style_banding_shades_the_header_row` (flow) + `table_shading` unit tests. **DOCX conditional-formatting import** (2026-07-08): the DOCX styles reader now parses a `w:type="table"` style's band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`), and each `w:tblStylePr` region's cell shading (`w:type` + `w:tcPr/w:shd`) into a new `DocxTableStyleProps`/`DocxTblStylePr` model; the styles mapper translates them into `TableStyle.table_props` (band sizes + base `background_color`) and the `conditional` region map (`map_table_region` maps the twelve OOXML region names; unknown or unshaded regions are skipped). So a real Word document that uses a built-in banded style (e.g. *List Table*/*Grid Table Accent*) now imports its conditional shading and — via the layout wiring above under the default `w:tblLook` — **paints banded rows/header end-to-end**. Tested by `parses_table_style_banding` (reader) + `table_style_conditional_formatting_maps` (mapper). **Per-table `w:tblLook` import** (2026-07-08): the DOCX reader now parses each table instance's `w:tblLook` (both the explicit `w:firstRow`/`w:noHBand`/… attributes and the legacy `w:val` hex bitmask, into a `DocxTblLook`); the mapper encodes it (via the doc-model `TableLook::encode_attr`, format-neutral) into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`), and the flow engine reads it (`table_shading::table_look`) so a table that turns off banding or enables the last-row/last-column region renders with **its** active regions instead of the assumed default. Tested by `parse_tbl_look_*` (reader), `map_tbl_look` (mapper), `table_look_attr_round_trips` (model codec), and `table_look_disabling_first_row_suppresses_style_shading` (flow, end-to-end). **DOCX banding export** (2026-07-08): the export half now writes table-style banding, so it survives a full DOCX round-trip. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"` (band sizes → `w:tblPr`, base shading → `w:tcPr/w:shd`, each conditional region → `w:tblStylePr w:type="…"` with its `w:tcPr/w:shd`), and writes the table instance's `w:tblLook` (both explicit boolean attributes and the legacy `w:val` bitmask) into its `w:tblPr` from the `"tbllook"` attr. Tested by 4 writer unit tests + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact). **ODT cell-shading export** (2026-07-08): the ODF-native representation of table shading — ODF bakes region shading into **per-cell** styles rather than conditional regions (LibreOffice's model), and the ODT writer previously dropped all cell formatting. `AutoStyles::cell_style` now emits a deduplicated automatic `` carrying `fo:background-color` for each shaded cell (`TC{n}` names), referenced by `table:style-name` on the ``; ODT import of `fo:background-color` already existed (`map_cell_props`), so a shaded cell now round-trips through ODT. Tested by `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer) and `cell_background_round_trips_via_table_cell_style` (end-to-end ODT round-trip). **ODT banding resolution on export** (2026-07-08): the ODT table writer now **resolves a referenced table style's banding into per-cell backgrounds** — so a table that carries only a `"style"` reference + `"tbllook"` (e.g. a DOCX-imported banded table) exports its bands to ODT as concrete per-cell shading. The writer flattens the rows, assigns each cell its grid column (a coverage-grid mirror of the layout's `assign_cell_columns`, honouring `col_span`/`row_span`), then computes each cell's effective background = its direct shading **else** `resolve_cell_shading(style, look, row, col, rows, cols)` (the same doc-model resolver the layout uses), baking the result into the per-cell `table-cell` style. The style catalog is threaded to the writer via a `Cx.table_styles` clone. Tested by `table_style_banding_resolves_into_per_cell_shading_on_odt_export` (a firstRow-banded style with no direct shading → header cells come back shaded, body cells not). **ODT table-level `table:style-name`** (2026-07-08): the ODT writer now emits a named `` for each catalog table style (`write/table_style.rs`, into `styles.xml`'s ``), carrying table-level geometry — `style:width`/`style:rel-width` (from `TableProps.width`), `table:align`, and `fo:background-color` — and references it via `table:style-name` on the ``. Import restores the **reference** (`OdfTable.style_name` → `Table::set_style_name` in `map_table`, one line — the reader already parsed it). So a table's named style survives an ODT round-trip. Tested by 4 writer unit tests (`emits_width_alignment_and_background`, `percent_width_uses_rel_width`, `a_style_with_no_geometry_omits_table_properties`, `synthetic_styles_are_skipped`) + `table_style_name_reference_round_trips` (end-to-end); schema validation green. **Not yet:** ODT import of the table-style *definition* back into the catalog (the reference survives but width/align/bg aren't re-read into a `TableStyle` yet), cell **borders**/padding export, `w:cnfStyle`, conditional character formatting, and the editing UI. | | **Page Number Format** | Yes | Yes | No | The page-number numbering scheme is imported in **both formats** into `PageLayout.page_number_format` and applied through `FieldContext`: the PAGE field is formatted via the shared list-marker converter (`lowerRoman`→i, ii, iii; `upperRoman`; `lowerLetter`/`upperLetter`); NUMPAGES stays decimal. **DOCX:** `w:pgNumType @w:fmt`/`@w:start` — the section restart (`page_number_start`) also offsets the displayed number from the section's first physical page. **ODT:** `style:num-format` on `style:page-layout-properties` (the active master page's layout) is read into `OdfPageLayout.num_format` and mapped through the same `map_numbering_scheme` helper shared with list numbering; decimal (`"1"`/absent) is left unset (the renderer default). Tested by `substitution_formats_page_number_as_lower_roman` (DOCX), `read_stylesheet_page_layout_num_format` (ODT reader), and `page_num_format_lower_roman_maps`/`page_num_format_upper_alpha_maps`/`page_num_format_decimal_and_absent_stay_none` (ODT mapper). ODT page-number *restart* (the per-paragraph `style:page-number`) remains a follow-up.

The four table-geometry helpers (measure_cell_height, resolve_column_widths, flow_cell_blocks, assign_cell_columns) are a self-contained 247-line unit whose only caller is flow_table. Extracted them into a new flow_table_geom.rs (269 lines, under the ceiling), declared as the table_geom #[path] submodule per the established flow_*.rs sibling pattern. They reach FlowState / flow_block / get_items_max_x via super:: (all three made pub(super)); the four moved fns are pub(super) so the parent's flow_table can call them. flow.rs 1948 -> 1702 (baseline ratcheted; the --update also records the downward drift several files picked up from the quick-xml merge). New file correctly excluded from the baseline (<=300). loki-layout suite green (188 lib + 11 integration binaries), clippy clean, fmt clean. flow.rs and para.rs remain the top offenders; further cuts (flow_table itself needs a 2-file sub-split) still pending.

The page-field detection and substitution cluster (visit_inline_vecs_mut, inlines_contain_page_field, page_layout_has_page_fields, blocks_contain_page_field, substitute_page_fields) is a 170-line unit that is fully self-contained — pure block/inline traversal with no FlowState and no flow helpers — so it moves out with only type imports. Extracted into a new flow_page_fields.rs (182 lines) as the page_fields #[path] submodule. flow.rs now calls page_fields::substitute_page_fields / blocks_contain_page_field; the pub(crate) page_layout_has_page_fields (used by incremental.rs via crate::flow::) is re-exported from flow.rs so its external path is unchanged. flow_tests.rs imports the two moved pub(super) fns it exercises. flow.rs 1702 -> 1535 (baseline ratcheted); total across both cuts 1948 -> 1535 (-413).

Extracted into a new para_props_map.rs (127 lines) as the para_map #[path] submodule. resolve_para_props now calls para_map::map_para_props; the module calls the already-public super::{resolve_color, pts_to_f32, convert_border}, so no new visibility promotions were needed.

New file excluded from the baseline (<=300). loki-layout suite green (188 lib + 11 integration binaries), clippy clean, fmt clean. Session running total across this split pass: five cuts over three files (flow.rs -413, para.rs -158, resolve.rs -113) into four new cohesive submodules; baseline down to 31 over-ceiling files.

Extracted into flow_table_paint.rs (246 lines) as the table_paint #[path] submodule: - measure_row_heights: passes 1-2 (size row_span==1 cells, then grow the last spanned row for taller row_span>1 cells) -> Vec. - emit_row_cell_decorations: pass 3b (per-page cell background + border rects, direct shading over table-style banding), including its two Y/height closures. Carries #[allow(clippy::too_many_arguments)] for its 16 row-geometry inputs, matching the existing flow_cell_blocks precedent. flow_table now calls table_paint::measure_row_heights / emit_row_cell_decorations. The move is verbatim apart from cell_cols[row_idx] -> the passed cell_cols_row slice and dropping a now-redundant &look (look is a &TableLook param). Four imports that migrated with the code (PositionedBorderRect, convert_border, resolve_color, cell_style_shading) removed from flow.rs. flow.rs 1535 -> 1362 (baseline ratcheted); new file excluded (<=300). The table layout tests (spanning/vMerge/rotation/vertical-align/clip/ banding) are the real regression guard and all pass: 188 lib + 11 integration binaries green, clippy -D warnings clean, fmt clean. Session total: six cuts over three files (flow.rs -586, para.rs -158, resolve.rs -113 = -857 lines) into five new submodules; flow.rs is now off the top-two offenders.

charset=UTF-8 Content-Transfer-Encoding: 8bit Second function-internal cut, on layout_paragraph_uncached (~630 lines, the last monster). Extract its two selection-geometry underlay phases — highlight/background fills (gap #10) and spelling squiggles — into a new para_underlays.rs (123 lines) as the underlays #[path] submodule. Both passes resolve a byte range to per-line extents via Parley selection geometry and append behind the glyph runs, so they only read the built layout and push to items — self-contained. They repeated the same hanging-indent + drop-cap-shift math, now factored into a private line_indent helper. layout_paragraph_uncached calls underlays::emit_highlight_underlays / emit_spelling_squiggles. The SPELL_SQUIGGLE_COLOR const moved with its sole user; DecorationKind and PositionedDecoration imports (now used only there) removed from para.rs. para.rs 1698 -> 1626 (baseline ratcheted); new file excluded (<=300). loki-layout suite green (188 lib + 11 integration binaries) — the spell and highlight rendering paths are exercised there — clippy -D warnings clean, fmt clean. Session total: seven cuts over three files (flow.rs -586, para.rs -230, resolve.rs -113 = -929 lines) into six new submodules.

charset=UTF-8 Content-Transfer-Encoding: 8bit styles.rs cut #2 — a cohesive-cluster extraction on the production body now that the inline tests are gone. The page-layout and master-page parsers (parse_page_layout, parse_header_footer_style, parse_master_page, parse_header_footer_paras, ~264 lines) form a self-contained group whose only external callers are read_stylesheet (via parse_page_layout and parse_master_page). Moved into a new styles_page.rs (288 lines) as the page #[path] submodule. The two entry points are pub(super); the header/footer helpers stay private. The module calls super::skip_element (pub(crate)) and carries styles.rs's #![allow(dropping_references)] (the cluster uses the same drop(ref) NLL hints). read_stylesheet now calls page::parse_page_layout / page::parse_master_page. Five imports that migrated with the cluster (OdfHeaderFooterProps, OdfPageLayout, OdfParagraph, parse_plp_columns, read_paragraph) removed from styles.rs. styles.rs 1298 -> 1037 (baseline ratcheted); new file excluded (<=300). loki-odf lib suite green (156), clippy clean, fmt clean. Session total: nine cuts (flow.rs -586, para.rs -230, resolve.rs -113, styles.rs -517 = -1446 lines) across seven new submodules + one test-file extraction.

The list-level parsers (parse_list_level_props + parse_label_alignment_child, ~146 lines) — a cohesive unit whose only external caller is parse_list_style — moved into a new styles_list.rs (167 lines) as the list #[path] submodule. parse_list_level_props is pub(super); parse_label_alignment_child stays private (called only within the cluster). The module calls super::{parse_text_props_attrs, skip_element} (parse_text_props_attrs promoted to pub(super)) and carries #![allow(dropping_references)]. parse_list_style now calls list::parse_list_level_props. styles.rs 1037 -> 892 (baseline ratcheted); new file excluded (<=300). loki-odf lib suite green (156), clippy clean, fmt clean. Running total: ten cuts, -1591 lines across eight new submodules + one test-file extraction.

Use the two established techniques (inline-test extraction, directory split); update the baseline with `--update` per split. **In progress — `flow.rs` cut #1 ✅ 2026-07-08:** the four table-geometry helpers (`measure_cell_height`, `resolve_column_widths`, `flow_cell_blocks`, `assign_cell_columns`) — a cohesive 247-line unit whose only caller is `flow_table` — extracted into a new `flow_table_geom.rs` (269 lines, under the ceiling) declared as the `table_geom` `#[path]` submodule (the established `flow_*.rs` sibling pattern), accessing `FlowState`/`flow_block`/`get_items_max_x` via `super::` (both made `pub(super)`). `flow.rs` **1948 → 1702** (baseline ratcheted); the whole `loki-layout` suite (188 lib + 11 integration binaries) green, clippy clean. **`flow.rs` cut #2 ✅ 2026-07-08:** the PAGE/NUMPAGES field detection + substitution cluster (`visit_inline_vecs_mut`, `inlines_contain_page_field`, `page_layout_has_page_fields`, `blocks_contain_page_field`, `substitute_page_fields`) — a 170-line unit that is *fully self-contained* (pure block/inline traversal, no `FlowState`, no flow helpers) — extracted into a new `flow_page_fields.rs` (182 lines) as the `page_fields` submodule. `flow.rs` calls `page_fields::substitute_page_fields`/`blocks_contain_page_field`; the `pub(crate)` `page_layout_has_page_fields` (used by `incremental.rs`) is re-exported from `flow.rs` so its external path is unchanged. `flow.rs` **1702 → 1535**; suite green (188 lib + 11 integration), clippy clean. **Total so far: `flow.rs` 1948 → 1535 (−413) across two cuts.** **`para.rs` cut #1 ✅ 2026-07-08:** the tab-stop cluster (`next_tab_stop_resolved`, `emit_tab_leader`, the `TabPlan` struct, `compute_tab_plans`, plus the `DEFAULT_TAB_INTERVAL` const) — a cohesive 160-line unit — extracted into a new `para_tabs.rs` (175 lines) as the `tabs` submodule; `layout_paragraph_uncached` calls `tabs::compute_tab_plans`/`emit_tab_leader` and uses `tabs::TabPlan` (its fields made `pub(super)`), accessing `super::ResolvedTabStop`. `para.rs` **1856 → 1698**; suite green (188 lib + 11 integration), clippy clean. `para.rs` (now #1 at 1698, its monster `layout_paragraph_uncached` still ~640 lines) and `flow.rs` remain the top offenders; further cuts (single >300 functions needing 2-file sub-splits) still pending. **`resolve.rs` cut #1 ✅ 2026-07-08:** the `ParaProps → ResolvedParaProps` mapping (`map_para_props` + `resolve_spacing`) extracted into a new `para_props_map.rs` (127 lines) as the `para_map` submodule — one external caller (`resolve_para_props` → `para_map::map_para_props`), the module calling the already-public `super::{resolve_color, pts_to_f32, convert_border}`; six now-unused imports removed from `resolve.rs`. `resolve.rs` **978 → 865**. **`flow.rs` cut #3 ✅ 2026-07-08 (first *function-internal* split):** `flow_table` itself (~420 lines, the last monster in the file) sub-split by extracting two of its phases — the row-height measurement (passes 1–2) and the per-row cell background/border decoration emission (pass 3b, incl. its two Y/height closures) — into a new `flow_table_paint.rs` (246 lines) as the `table_paint` submodule. `flow_table` now calls `table_paint::measure_row_heights(state, &rows, &cell_cols, &col_widths, idx)` and `table_paint::emit_row_cell_decorations(…)` (the latter carries `#[allow(clippy::too_many_arguments)]` — 16 row-geometry inputs, matching the `flow_cell_blocks` precedent). Verbatim move apart from `cell_cols[row_idx]` → the passed `cell_cols_row` slice and dropping a now-redundant `&look`.

Use the two established techniques (inline-test extraction, directory split); update the baseline with `--update` per split. **In progress — `flow.rs` cut #1 ✅ 2026-07-08:** the four table-geometry helpers (`measure_cell_height`, `resolve_column_widths`, `flow_cell_blocks`, `assign_cell_columns`) — a cohesive 247-line unit whose only caller is `flow_table` — extracted into a new `flow_table_geom.rs` (269 lines, under the ceiling) declared as the `table_geom` `#[path]` submodule (the established `flow_*.rs` sibling pattern), accessing `FlowState`/`flow_block`/`get_items_max_x` via `super::` (both made `pub(super)`). `flow.rs` **1948 → 1702** (baseline ratcheted); the whole `loki-layout` suite (188 lib + 11 integration binaries) green, clippy clean. **`flow.rs` cut #2 ✅ 2026-07-08:** the PAGE/NUMPAGES field detection + substitution cluster (`visit_inline_vecs_mut`, `inlines_contain_page_field`, `page_layout_has_page_fields`, `blocks_contain_page_field`, `substitute_page_fields`) — a 170-line unit that is *fully self-contained* (pure block/inline traversal, no `FlowState`, no flow helpers) — extracted into a new `flow_page_fields.rs` (182 lines) as the `page_fields` submodule. `flow.rs` calls `page_fields::substitute_page_fields`/`blocks_contain_page_field`; the `pub(crate)` `page_layout_has_page_fields` (used by `incremental.rs`) is re-exported from `flow.rs` so its external path is unchanged. `flow.rs` **1702 → 1535**; suite green (188 lib + 11 integration), clippy clean. **Total so far: `flow.rs` 1948 → 1535 (−413) across two cuts.** **`para.rs` cut #1 ✅ 2026-07-08:** the tab-stop cluster (`next_tab_stop_resolved`, `emit_tab_leader`, the `TabPlan` struct, `compute_tab_plans`, plus the `DEFAULT_TAB_INTERVAL` const) — a cohesive 160-line unit — extracted into a new `para_tabs.rs` (175 lines) as the `tabs` submodule; `layout_paragraph_uncached` calls `tabs::compute_tab_plans`/`emit_tab_leader` and uses `tabs::TabPlan` (its fields made `pub(super)`), accessing `super::ResolvedTabStop`. `para.rs` **1856 → 1698**; suite green (188 lib + 11 integration), clippy clean. `para.rs` (now #1 at 1698, its monster `layout_paragraph_uncached` still ~640 lines) and `flow.rs` remain the top offenders; further cuts (single >300 functions needing 2-file sub-splits) still pending. **`resolve.rs` cut #1 ✅ 2026-07-08:** the `ParaProps → ResolvedParaProps` mapping (`map_para_props` + `resolve_spacing`) extracted into a new `para_props_map.rs` (127 lines) as the `para_map` submodule — one external caller (`resolve_para_props` → `para_map::map_para_props`), the module calling the already-public `super::{resolve_color, pts_to_f32, convert_border}`; six now-unused imports removed from `resolve.rs`. `resolve.rs` **978 → 865**. **`flow.rs` cut #3 ✅ 2026-07-08 (first *function-internal* split):** `flow_table` itself (~420 lines, the last monster in the file) sub-split by extracting two of its phases — the row-height measurement (passes 1–2) and the per-row cell background/border decoration emission (pass 3b, incl. its two Y/height closures) — into a new `flow_table_paint.rs` (246 lines) as the `table_paint` submodule. `flow_table` now calls `table_paint::measure_row_heights(state, &rows, &cell_cols, &col_widths, idx)` and `table_paint::emit_row_cell_decorations(…)` (the latter carries `#[allow(clippy::too_many_arguments)]` — 16 row-geometry inputs, matching the `flow_cell_blocks` precedent).

The table-reading family (read_table + read_table_header_rows / read_table_row / read_table_cell, ~253 lines) is a cohesive cluster whose only external caller is read_body_children. Moved into a new document_table.rs (274 lines) as the table #[path] submodule. read_table stays pub(crate) and is re-exported from document.rs (pub(crate) use table::read_table;), so read_body_children's call site is unchanged and the crate path stays stable; the three row/cell helpers are private to the module. Cell content recurses back through super::{read_paragraph, read_list, skip_element} and nested read_table. The whole crate::odt::model::tables import moved with the cluster. Module carries #![allow(dropping_references)]. document.rs 1002 -> 751 (baseline ratcheted); new file excluded (<=300). loki-odf lib suite green (156), clippy clean, fmt clean. Running total: twelve cuts, -2332 lines across nine new submodules + two test-file extractions.

Five imports that migrated with the cluster removed from `styles.rs`. `styles.rs` **1298 → 1037**; `loki-odf` lib suite green (156), clippy clean. **Session running total: nine cuts, `flow.rs` −586 / `para.rs` −230 / `resolve.rs` −113 / `styles.rs` −517 = −1446 lines across seven new submodules + one test-file extraction; baseline still 31 files.

Suites green (loki-ooxml 185, loki-doc-model 187), clippy clean, fmt clean. Running total: seventeen cuts, -3307 lines across nine new production submodules + seven test-file extractions.

Moved into a new write/document_table.rs as the table #[path] submodule. write_table is pub(super); the row/cell helpers stay private. Cell block content recurses through super::write_blocks; the vMerge-tracking rows and the w:tblLook call (now crate::docx::write::table_style::write_tbl_look via an explicit use) came across cleanly. Three imports that migrated with the cluster (Table, Cell, color_to_hex) removed from document.rs. document.rs 1073 -> 904 (baseline ratcheted); new file excluded (<=300). Full loki-ooxml suite green (30 test binaries incl. DOCX round-trips), clippy clean, fmt clean.

document.rs's body parser calls table::parse_table, and document_cell.rs (nested table in a cell) now imports super::table::parse_table. parse_table_row calls super::cell::parse_table_cell. parse_tbl_look is pub(super) so the extracted document_tests.rs can reach it via super::table. The whole crate::docx::model::styles import (all six table types) moved out of document.rs. document.rs 1003 -> 845 (baseline ratcheted); new file excluded (<=300). Full loki-ooxml suite green (30 test binaries incl. DOCX round-trips), clippy clean, fmt clean. Running total: twenty-two cuts, -3931 lines across thirteen new production submodules + seven test-file extractions.

Text-box paragraphs recurse through super::read_paragraph; the module carries #![allow(dropping_references)]. The frames model import moved out of document.rs. document.rs 751 -> 588 (baseline ratcheted); new file excluded (<=300). loki-odf lib suite green (156), clippy clean, fmt clean.

All 188 lib + 11 integration binaries green (the hit-test / cursor / selection-rect tests exercise the moved methods), clippy -D warnings clean, fmt clean. Plan 6.3 row updated. Running total: twenty-six cuts, -4552 lines across seventeen new production submodules + seven test-file extractions; deferred-features 4b.5 and 6.3 both unblocked.

Four imports that migrated with the code (`PositionedBorderRect`, `convert_border`, `resolve_color`, `cell_style_shading`) removed from `flow.rs`. `flow.rs` **1535 → 1362**; all 188 lib + 11 integration binaries green (the table cases — spanning/vMerge/rotation/v-align/clip/banding — are the real regression guard), clippy `-D warnings` clean. **`para.rs` cut #2 ✅ 2026-07-08 (function-internal, on `layout_paragraph_uncached` ~630 lines):** the two selection-geometry underlay phases — highlight/background fills (gap #10) and spelling squiggles — extracted into a new `para_underlays.rs` (123 lines) as the `underlays` submodule (`emit_highlight_underlays` / `emit_spelling_squiggles`, sharing a private `line_indent` helper that de-duplicates the hanging-indent + drop-cap-shift math the two passes repeated). The `SPELL_SQUIGGLE_COLOR` const moved with its sole user; `DecorationKind`/`PositionedDecoration` imports (now only used there) removed from `para.rs`. `para.rs` **1698 → 1626**; suite green (188 lib + 11 integration), clippy clean. **`odt/reader/styles.rs` cut #1 ✅ 2026-07-08 (technique 1 — inline-test extraction):** the file still carried its `#[cfg(test)] mod tests { … }` inline (~258 lines); moved it to a sibling `styles_tests.rs` via `#[cfg(test)] #[path = "styles_tests.rs"] mod tests;` — **zero production-code change**. `styles.rs` **1554 → 1298** (baseline ratcheted); the 23 styles reader tests still run (now `odt::reader::styles::tests::*`), full `loki-odf` lib suite green (156), clippy clean. The extracted `_tests.rs` is exempt from the ceiling count. **Session running total: eight cuts, `flow.rs` −586 / `para.rs` −230 / `resolve.rs` −113 / `styles.rs` −256 = −1185 lines across six new submodules + one test-file extraction; baseline still 31 files. Leaders now `para.rs` 1626, then `odt/reader/document.rs` 1492 and `styles.rs` itself now down to 1298. **`styles.rs` cut #2 ✅ 2026-07-08 (cohesive-cluster extraction):** the page-layout + master-page parsers (`parse_page_layout`, `parse_header_footer_style`, `parse_master_page`, `parse_header_footer_paras`, ~264 lines) — whose only external callers are `read_stylesheet` (via the first two, made `pub(super)`) — moved into a new `styles_page.rs` (288 lines) as the `page` submodule, calling `super::skip_element` and carrying the module's `#![allow(dropping_references)]`. Five imports that migrated with the cluster removed from `styles.rs`. `styles.rs` **1298 → 1037**; `loki-odf` lib suite green (156), clippy clean. **Session running total: nine cuts, `flow.rs` −586 / `para.rs` −230 / `resolve.rs` −113 / `styles.rs` −517 = −1446 lines across seven new submodules + one test-file extraction; baseline still 31 files. Leaders now `para.rs` 1626, then `odt/reader/document.rs` 1492; `styles.rs` is down to 1037. **`styles.rs` cut #3 ✅ 2026-07-08:** the list-level parsers (`parse_list_level_props` + `parse_label_alignment_child`, ~146 lines) → new `styles_list.rs` (167 lines) as the `list` submodule; `parse_list_style` calls `list::parse_list_level_props`, the module calls `super::{parse_text_props_attrs, skip_element}` (the former promoted to `pub(super)`). `styles.rs` **1037 → 892**; `loki-odf` green (156), clippy clean. **`odt/reader/document.rs` cut #1 ✅ (inline-test extraction, ~490 lines → `document_tests.rs`; 1492 → 1002) and cut #2 ✅ (table-reading family `read_table`/`read_table_header_rows`/`read_table_row`/`read_table_cell` → `document_table.rs` (274 lines) as the `table` submodule, `read_table` re-exported to keep its `pub(crate)` path; 1002 → 751). Three more inline-test extractions ✅: `loki-vello/scene.rs` (948 → 727, `scene_tests.rs`), `loki-odf/package.rs` (644 → 410, `package_tests.rs`), `loki-ooxml/docx/mapper/document.rs` (611 → 448, `document_tests.rs`). Then: `docx/mapper/props.rs` (inline tests → `props_tests.rs`, 582 → 357) and `loki-doc-model/document.rs` (inline tests → `document_tests.rs`, 440 → 317); `loki-doc-model/document.rs` cluster cut (locale paper-size helpers → `document_paper.rs`, 317 → **290, under the ceiling → left the baseline**); `docx/mapper/props.rs` cluster cut (`map_rpr` → `props_rpr.rs`, re-exported, 357 → **268, under the ceiling → left the baseline**); `docx/reader/document.rs` table-cell cluster (`parse_table_cell`/`parse_tc_*` → `document_cell.rs`, 1185 → 1004). Further cohesive-cluster cuts on the format readers/writers: `docx/write/document.rs` table serialization → `write/document_table.rs` (1073 → 902); `docx/reader/document.rs` cell parsers → `document_cell.rs` and table-level parsers → `document_table.rs` (1185 → 845, two cuts, with the table↔cell cross-module refs threaded); `odt/reader/document.rs` frame parsers → `document_frame.rs` (751 → 586, `read_frame_kind` re-exported for `inlines.rs`); `odt/reader/styles.rs` paragraph-property parsers → `styles_para.rs` (892 → 764). **`flow.rs` cut #4 ✅ 2026-07-08 (function-internal, unblocks 4b.5):** `flow_table`'s pass 3a — the per-cell content-flowing loop (rotation → `RotatedGroup`, vertical alignment, single-page clipping) — extracted into `flow_table_cells.rs` (`flow_row_cells`, 200 lines) as the `table_cells` submodule; `flow_table` calls it once per row and feeds the returned `cell_starts` to the pass-3b emitter. `row_y_start`/`row_page` became fn locals; `cell_flat` threads as `&mut`. This lands the `TODO(rotated-cell-editing)` path in a sub-ceiling module with headroom (see 4b.5). `flow.rs` **1362 → 1209**; all 188 lib + 11 integration binaries green (table rotation/spanning/vMerge/v-align/clip), clippy clean. **`para.rs` cut #3 ✅ 2026-07-08 (unblocks 6.3):** `ParagraphLayout`'s read-only query methods (`hit_test_point`, `line_end_offset`, `cursor_rect`, `selection_rects`, `line_indent`) extracted into `para_query.rs` as `impl super::ParagraphLayout` (198 lines) — the home for the pending Option-B y-range filter (6.3). `para.rs` **1626 → 1447**; 188 lib + 11 integration binaries green (hit-test/cursor/selection tests), clippy clean. **Session running total: twenty-six cuts, −4552 lines across seventeen new production submodules + seven test-file extractions; two files driven fully under the 300-line ceiling (backlog 31 → 29); deferred-features 4b.5 and 6.3 both unblocked (their code paths / natural homes now sit in sub-ceiling modules with headroom); all touched suites green (loki-layout 188, loki-odf 156, loki-ooxml 30 binaries incl.

Implement the core of feature 4b.5 on the sub-ceiling `flow_table_cells.rs` module the Phase-7.1 split created. Model (loki-layout): - New `CellRotation` (result_rotation.rs) mirrors the paint-time `RotatedGroup` affine: `page = pivot_page + Rot(deg)·(local − pivot_local)`, with `local_to_page` / `page_to_local` inverses. - `PageParagraphData` gains a `rotation: Option` field; when set, `origin` is in the cell's content-local frame. New `hit_local` / `local_to_page` helpers centralise the (inverse) transform so rotation lives in exactly one place. Producer: - `flow_cell_blocks` now tags each cell paragraph with its `NestedEditing` path and returns the editing entries alongside items; the rotated branch records them with a `CellRotation` built from the same pivots the renderer uses. Consumers (no regression — upright cells hit the identity path): - loki-layout `ContinuousLayout::{hit_test, cursor_rect_canvas, selection_rects}` and loki-text `hit_test_page` route through the centralised helpers. Clicking a rotated cell now resolves to the correct character; caret/selection positions are rotation-correct. Tests: `result_tests` (transform round-trip, `hit_local`) and `flow_tests::rotated_cell_emits_editing_data_with_rotation` (end-to-end). loki-layout 192 lib + 11 integration binaries and loki-text 195 lib green; clippy -D warnings clean; result.rs kept under the ceiling by extracting the rotation types to result_rotation.rs. Follow-up (TODO(rotated-cell-caret), documented in fidelity-status.md): the rendered caret *line* stays upright (a tilted caret needs CursorRect + vello to carry rotation) and up/down arrow navigation across rotated cells still uses raw origin translation.

DOCX `wp:wrapSquare`/`wrapTight`/`wrapThrough`/`wrapTopAndBottom`/`wrapNone` (+ `wrapText` side, anchor `behindDoc`) and ODF `style:wrap` + `style:run-through` both map. **Floats are painted and text wraps beside them** (`flow_float.rs`): for a `Square`/`Tight`/`Through`/non-behind-`None` float the flow engine reserves a side band (float on the left when text occupies the right, and vice-versa; `Both`/`Largest` default to a left float) by widening the paragraph's start/end indent, paints the image in that band, and reserves its height so the next paragraph clears it. Verified against the Word reference on ACID TC-DOCX-023 (margin-anchored image, text wrapping to its right). **Per-line precision:** lines beside the float are narrowed while lines below it reclaim the full column (two-pass `para_band` layout, shared with drop caps) — verified against the Word reference where the text below the image returns to full width. **Cross-paragraph wrap:** a float taller than its anchoring paragraph keeps wrapping the *following* paragraphs (tracked as `flow::float_impl::ActiveFloat`) until its bottom is cleared; bounded to a single page and to consecutive plain paragraphs (a table/list/rule or page break reserves the float's remaining height instead). **Limitations (gap #12):** the live-editor path keeps the uniform-narrow fallback; the tight wrap **contour** is approximated by the bounding box; true `behindDoc` overlap and absolute anchor positioning are not yet done. `TopAndBottom`/behind-text floats still stack as a block. Not re-exported to DOCX/ODT. **EPUB export** now maps a side-wrapping float to a CSS `float:left/right` on the `` so the reflowable book flows text around it (the reflow-target equivalent of the paginated wrap band; `behind`/`TopAndBottom` stay block-level). **ODT parity:** a non-`as-char` `draw:frame` image carrying a `style:wrap` graphic style is now mapped to a floating inline image (wrap + `FLOATING_CLASS`) in its anchoring paragraph — the same representation as the DOCX path — and the frame's `svg:width`/`svg:height` are carried as `cx_emu`/`cy_emu` (without which the layout treated every ODT image as zero-sized and skipped it). Tested: `flow_float` unit tests + `tall_float_wraps_following_paragraph` + `anchor_drawing_carries_wrap_mode` (DOCX), `read_stylesheet_graphic_wrap` + `floating_image_frame_becomes_inline_float_with_size` (ODT).

It now emits a content-matrix transform so the text exports at its true angle, matching the on-screen loki-vello renderer. The PDF renderer bakes a per-leaf y-flip F into every leaf, so children are already in y-up space. New `page_rotate::rotated_group_ctm` builds the CTM `C = F·M·F`, where `M = T(pivot)·R(θ)·T(-pivot_local)` is the exact loki-vello rotation; rendering children under C with a zero offset places each child at `F(M·p_local)` — the screen placement flipped into PDF space. `page.rs` wraps it in `q cm … Q`. Tested: `page_rotate` matrix unit tests (θ=0 degenerate reproduces the old offset-and-flip, hand-computed 90° matrix, four-corner round-trip against the screen transform) and `rotated_group_emits_transform_and_children` (the content stream carries `cm` + the child fill inside save/restore).

An image tagged with `FLOATING_CLASS` but carrying no explicit wrap keys (e.g. an anchored DOCX `wp:anchor` whose wrap child was absent or unrecognised — the mapper still adds the class) was read as `None` by `FloatWrap::read` and laid out inline, not floating. - Add `FloatWrap::read_or_class_default`: falls back to a square/both-sides float when the attr is marked floating but has no wrap keys; returns None for a genuinely inline attr. - `resolve.rs` collects images via the new method, so such images now flow as side-wrapping floats through the existing `flow_float` path. - Refresh the stale `float` module doc (the engine does flow text around floats now) and drop the resolved `TODO(floating-image)`.

The layout already flows a cell's blocks through `flow_block`/`flow_table`, so the nested table lays out and clips to the cell box with no layout change. The ODF document mapper (`odt/mapper/document.rs`, formerly 1378 lines) was split into a `document/` directory (`mod`/`inlines`/`frames`/`blocks`/`page`/`meta` + moved tests) so the cell mapper could grow under the file-size ceiling. Tested by `nested_table_in_cell_maps_to_table_block` (DOCX), `nested_table_in_cell_is_parsed_into_cell_content` (ODT reader), and `nested_table_in_cell_maps_to_inner_table_block` (ODT mapper). Not re-exported. | | **Table Styles** | Partial | Partial | Partial | **Style reference** (2026-07-08, Spec 05 4a.3 foundation): a table now remembers its **named style** (OOXML `w:tblStyle` / ODF `table:style-name`). It is stored in the table's `NodeAttr` `"style"` key — the same convention a heading uses — so it round-trips through the Loro bridge (part of the serde table skeleton, no bridge change) and through **DOCX** export/import (the reader already parsed `w:tblStyle`; the mapper now carries it and the writer emits it before `w:tblW`). Read via `Table::style_name()`. Tested by `table_style_round_trip.rs` (DOCX) + `table_style_reference_round_trips_through_the_bridge` (CRDT). **Banding/conditional model + resolver** (2026-07-08): `TableStyle` now carries a `conditional: IndexMap` map (the twelve OOXML `w:tblStylePr` regions — first/last row/col, the four corners, the horizontal/vertical bands, plus `WholeTable`) and `TableProps` gained `row_band_size`/`col_band_size`; a `TableLook` struct models the per-table `w:tblLook` flags (default `04A0`: header row + first column + row banding). A pure `resolve_cell_shading(style, look, row, col, rows, cols)` (`style/table_banding.rs`) returns the shading a style contributes to a cell, honouring OOXML precedence (corners > first/last row > first/last col > horizontal bands > vertical bands > whole-table) and resolving *per-property* (a higher region with no shading falls through), with the base table shading as the final fallback. 12 unit tests (banding parity, band size, header/first-col exclusion, corner-needs-both-flags, precedence ordering, out-of-range). **Rendered** (2026-07-08): the flow engine now **consults the table style** when painting cell backgrounds — a new `loki-layout` `table_shading` module (`resolve_table_style` looks the style up in the catalog by the table's `"style"` attr; `cell_style_shading` calls the resolver) layers style/banding shading **under** any direct `CellProps` shading at the Pass-3b cell-paint seam (`flow.rs`), so a table that references a banded style paints its header/banded cells with no direct cell shading needed. The active `w:tblLook` is not yet imported, so Word's default (`04A0`) is assumed for now (`TODO(table-tbllook-import)`). Tested by `table_style_banding_shades_the_header_row` (flow) + `table_shading` unit tests. **DOCX conditional-formatting import** (2026-07-08): the DOCX styles reader now parses a `w:type="table"` style's band sizes (`w:tblStyleRowBandSize`/`w:tblStyleColBandSize`), base whole-table cell shading (`w:tcPr/w:shd`), and each `w:tblStylePr` region's cell shading (`w:type` + `w:tcPr/w:shd`) into a new `DocxTableStyleProps`/`DocxTblStylePr` model; the styles mapper translates them into `TableStyle.table_props` (band sizes + base `background_color`) and the `conditional` region map (`map_table_region` maps the twelve OOXML region names; unknown or unshaded regions are skipped). So a real Word document that uses a built-in banded style (e.g. *List Table*/*Grid Table Accent*) now imports its conditional shading and — via the layout wiring above under the default `w:tblLook` — **paints banded rows/header end-to-end**. Tested by `parses_table_style_banding` (reader) + `table_style_conditional_formatting_maps` (mapper). **Per-table `w:tblLook` import** (2026-07-08): the DOCX reader now parses each table instance's `w:tblLook` (both the explicit `w:firstRow`/`w:noHBand`/… attributes and the legacy `w:val` hex bitmask, into a `DocxTblLook`); the mapper encodes it (via the doc-model `TableLook::encode_attr`, format-neutral) into the table's `NodeAttr` `"tbllook"` key (round-trips through the Loro bridge like `"style"`), and the flow engine reads it (`table_shading::table_look`) so a table that turns off banding or enables the last-row/last-column region renders with **its** active regions instead of the assumed default. Tested by `parse_tbl_look_*` (reader), `map_tbl_look` (mapper), `table_look_attr_round_trips` (model codec), and `table_look_disabling_first_row_suppresses_style_shading` (flow, end-to-end). **DOCX banding export** (2026-07-08): the export half now writes table-style banding, so it survives a full DOCX round-trip. A new `write/table_style.rs` emits each catalog `TableStyle` as a `w:style w:type="table"` (band sizes → `w:tblPr`, base shading → `w:tcPr/w:shd`, each conditional region → `w:tblStylePr w:type="…"` with its `w:tcPr/w:shd`), and writes the table instance's `w:tblLook` (both explicit boolean attributes and the legacy `w:val` bitmask) into its `w:tblPr` from the `"tbllook"` attr. Tested by 4 writer unit tests + `table_style_banding_and_tbllook_round_trip` (a banded style + non-default look survive export→import intact). **ODT cell-shading export** (2026-07-08): the ODF-native representation of table shading — ODF bakes region shading into **per-cell** styles rather than conditional regions (LibreOffice's model), and the ODT writer previously dropped all cell formatting. `AutoStyles::cell_style` now emits a deduplicated automatic `` carrying `fo:background-color` for each shaded cell (`TC{n}` names), referenced by `table:style-name` on the ``; ODT import of `fo:background-color` already existed (`map_cell_props`), so a shaded cell now round-trips through ODT. Tested by `cell_style_emits_background_and_dedupes` + `a_cell_without_shading_gets_no_style` (writer) and `cell_background_round_trips_via_table_cell_style` (end-to-end ODT round-trip). **ODT banding resolution on export** (2026-07-08): the ODT table writer now **resolves a referenced table style's banding into per-cell backgrounds** — so a table that carries only a `"style"` reference + `"tbllook"` (e.g. a DOCX-imported banded table) exports its bands to ODT as concrete per-cell shading. The writer flattens the rows, assigns each cell its grid column (a coverage-grid mirror of the layout's `assign_cell_columns`, honouring `col_span`/`row_span`), then computes each cell's effective background = its direct shading **else** `resolve_cell_shading(style, look, row, col, rows, cols)` (the same doc-model resolver the layout uses), baking the result into the per-cell `table-cell` style. The style catalog is threaded to the writer via a `Cx.table_styles` clone. Tested by `table_style_banding_resolves_into_per_cell_shading_on_odt_export` (a firstRow-banded style with no direct shading → header cells come back shaded, body cells not). **ODT table-level `table:style-name`** (2026-07-08): the ODT writer now emits a named `` for each catalog table style (`write/table_style.rs`, into `styles.xml`'s ``), carrying table-level geometry — `style:width`/`style:rel-width` (from `TableProps.width`), `table:align`, and `fo:background-color` — and references it via `table:style-name` on the ``. Import restores the **reference** (`OdfTable.style_name` → `Table::set_style_name` in `map_table`, one line — the reader already parsed it). So a table's named style survives an ODT round-trip. Tested by 4 writer unit tests (`emits_width_alignment_and_background`, `percent_width_uses_rel_width`, `a_style_with_no_geometry_omits_table_properties`, `synthetic_styles_are_skipped`) + `table_style_name_reference_round_trips` (end-to-end); schema validation green. **Not yet:** ODT import of the table-style *definition* back into the catalog (the reference survives but width/align/bg aren't re-read into a `TableStyle` yet), cell **borders**/padding export, `w:cnfStyle`, conditional character formatting, and the editing UI. | diff --git a/loki-doc-model/src/content/float.rs b/loki-doc-model/src/content/float.rs index 8156a2ea..df59432c 100644 --- a/loki-doc-model/src/content/float.rs +++ b/loki-doc-model/src/content/float.rs @@ -11,10 +11,10 @@ //! //!

The section break *type* (`w:type` continuous / nextPage / evenPage / oddPage) imports to `Section.start` (`SectionStart`); ODF has no explicit break element, so a **master-page transition** — a paragraph whose style resolves a `style:master-page-name` different from the running master page — implicitly begins a new section, always as `NewPage` (`document/sections.rs::build_sections`; a *leading* declaration on the first paragraph adopts the opening master without emitting an empty preceding section). Tested by `master_page_transition_splits_into_sections` / `leading_master_page_declaration_does_not_emit_empty_section`. **Mixed page sizes/orientations render correctly:** the editor/print painter sizes each page's white background and drop shadow from that page's own `page.page_size` (via `page_chrome_size`), so an A4 or landscape-Letter section no longer leaves a gray streak. Tested by `page_chrome_uses_per_page_size`. **`continuous` breaks share a page.** Consecutive sections joined by `continuous` breaks are flowed as one **page-sharing group** (`flow::flow_section_group`): the group's first section starts the pages and owns the page geometry + headers/footers (a continuous break cannot change page size), and each continuous member continues on the **same page** below the previous content, switching column layout mid-page via a fresh column band (`FlowState::column_top_y`). So the ACID page-11 "Unequal multi-column text in a continuous section" label is now followed by its two-column content on the same page instead of stranding the heading. Tested by `continuous_section_shares_previous_page` and `continuous_multi_column_section_flows_into_two_columns_on_shared_page` (layout) + `section_type_maps_to_section_start` (DOCX mapper). **Limitations:** continuous columns are filled top-to-bottom (fill-first, no height *balancing* — Word balances continuous-section columns evenly); `evenPage`/`oddPage` start a new page like `nextPage` (the blank-page insertion to reach an even/odd page is not yet emitted); and unequal column widths (`w:cols w:equalWidth="0"`) render as equal columns (per-column widths are not modelled). | +| **Hyperlinks** | Yes | Yes | Yes | External-URL links round-trip in both formats; a run's `link_url` is carried through layout and painted with a translucent blue hint underlay (`loki-vello`'s `paint_link_hint`). **Point→URL hit-testing (5.11, 2026-07-09):** `PageParagraphData::link_at` resolves a point to the hyperlink under it by testing each glyph run's hint box (rotation-inverted for rotated cells); `ContinuousLayout::link_at` (canvas frame) and `PageEditingData::link_at` (content-area-local, the paginated hit-test frame) delegate to it. Tested by 5 `result_tests` cases. **Pending:** the `loki-text` open-on-click gesture (a modifier + cross-platform URL opener) is not yet wired. | | **Document Metadata** | Yes | — | Yes | Core properties (title, subject, keywords, description, creator, last-modified-by, created/modified dates, language, revision) round-trip in both formats — DOCX via `docProps/core.xml` (OPC `CoreProperties`; the `serde` feature on `loki-opc` is enabled so the reader/writer are real, not stubs), ODT via `meta.xml`. **Extended Dublin Core** (publisher, contributors, rights, license, identifier, identifier-scheme, type, format, source, relation, coverage, issued, bibliographic-citation) round-trips too: `dc:identifier` uses the native core.xml element; the rest are carried as DOCX `docProps/custom.xml` custom properties / ODT `meta:user-defined` entries under reserved `dcmi:` names. The flattening is shared via `DublinCoreMeta::to_named_pairs`/`from_named_pairs` in `loki-doc-model`. Tested by `metadata_round_trip.rs` (DOCX) and `extended_dublin_core_round_trips` (ODT). Not yet written: custom user properties, `meta:editing-duration`, OOXML `docProps/app.xml`. | | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`). At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. **Columns are user-editable** (2026-07-06): the Layout ribbon tab's Columns group (one/two/three) applies `set_document_columns` and relayouts. | | **Headers & Footers** | Yes | Yes | Yes | DOCX export writes all three variants — default, first-page (`w:titlePg`), and even-page (`word/settings.xml` with `w:evenAndOddHeaders`) — as `w:hdr`/`w:ftr` parts with full block content; ODT export writes them into the master page. Round-trip tested (`even_page_headers_footers_round_trip`). | diff --git a/loki-layout/src/items.rs b/loki-layout/src/items.rs index c5900fc6..8c0eff8c 100644 --- a/loki-layout/src/items.rs +++ b/loki-layout/src/items.rs @@ -122,8 +122,10 @@ pub struct PositionedGlyphRun { pub synthesis: GlyphSynthesis, /// Hyperlink URL if this run is part of a link. `None` for non-link text. /// - /// TODO(link-click): interactive hit-testing deferred; only a visual hint - /// (blue tint underlay) is rendered by `loki-vello`. + /// A blue-tint underlay hint is rendered by `loki-vello`, and a point can be + /// resolved to its URL via `ContinuousLayout::link_at` / + /// `PageEditingData::link_at` (feature 5.11).

A plain click still positions the caret, so hyperlink text stays editable. - Reflow-mode open-on-click is left as a small follow-up (`TODO(link-click-reflow)`); the blue-tint hint renders in both modes. Verified: loki-renderer + loki-text build and `cargo clippy -p loki-renderer -p loki-text -- -D warnings` are clean; fmt + file-ceiling green. The URL-open side effect is isolated in `open_hyperlink_at`; the resolution core (`link_at`) is covered by the layout tests. Plan 5.11 + fidelity-status updated.

Tested by `continuous_section_shares_previous_page` and `continuous_multi_column_section_flows_into_two_columns_on_shared_page` (layout) + `section_type_maps_to_section_start` (DOCX mapper). **Limitations:** continuous columns are filled top-to-bottom (fill-first, no height *balancing* — Word balances continuous-section columns evenly); `evenPage`/`oddPage` start a new page like `nextPage` (the blank-page insertion to reach an even/odd page is not yet emitted); and unequal column widths (`w:cols w:equalWidth="0"`) render as equal columns (per-column widths are not modelled). | -| **Hyperlinks** | Yes | Yes | Yes | External-URL links round-trip in both formats; a run's `link_url` is carried through layout and painted with a translucent blue hint underlay (`loki-vello`'s `paint_link_hint`). **Point→URL hit-testing (5.11, 2026-07-09):** `PageParagraphData::link_at` resolves a point to the hyperlink under it by testing each glyph run's hint box (rotation-inverted for rotated cells); `ContinuousLayout::link_at` (canvas frame) and `PageEditingData::link_at` (content-area-local, the paginated hit-test frame) delegate to it.

Tested by 5 `result_tests` cases. **Interactive open:** in the paginated editor a **Ctrl/Cmd+click** on a link opens it in the browser (`webbrowser` crate) instead of placing the caret — the page tile reports the modifier through `on_tile_click`, and `hit_test::open_hyperlink_at` resolves + opens the URL; a plain click still positions the caret so link text stays editable. Reflow-mode open-on-click is a follow-up. | | **Document Metadata** | Yes | — | Yes | Core properties (title, subject, keywords, description, creator, last-modified-by, created/modified dates, language, revision) round-trip in both formats — DOCX via `docProps/core.xml` (OPC `CoreProperties`; the `serde` feature on `loki-opc` is enabled so the reader/writer are real, not stubs), ODT via `meta.xml`. **Extended Dublin Core** (publisher, contributors, rights, license, identifier, identifier-scheme, type, format, source, relation, coverage, issued, bibliographic-citation) round-trips too: `dc:identifier` uses the native core.xml element; the rest are carried as DOCX `docProps/custom.xml` custom properties / ODT `meta:user-defined` entries under reserved `dcmi:` names. The flattening is shared via `DublinCoreMeta::to_named_pairs`/`from_named_pairs` in `loki-doc-model`. Tested by `metadata_round_trip.rs` (DOCX) and `extended_dublin_core_round_trips` (ODT). Not yet written: custom user properties, `meta:editing-duration`, OOXML `docProps/app.xml`. | | **Multi-column Sections** | Yes | Yes | Yes | Column count, gap, and separator line round-trip in both formats — DOCX `w:cols` (`@w:num`/`@w:space`/`@w:sep`) and ODF `style:columns` (`fo:column-count`/`fo:column-gap` + `style:column-sep`). At **layout time** (paginated mode) the flow engine divides the content area into equal columns and fills each top-to-bottom before advancing to the next column and then the page (`flow_columns.rs`); the requested separator line is drawn between used columns. Continuous/reflow modes ignore columns by design. Tested by `export_columns.rs` / `multi_column_section_round_trips` (round-trip) and `text_flows_down_columns_before_paging` / `column_separator_line_is_drawn` (layout). Known limitations: columns are balanced only implicitly (fill-first, no height balancing), and footnotes still flow in the last active column. **Columns are user-editable** (2026-07-06): the Layout ribbon tab's Columns group (one/two/three) applies `set_document_columns` and relayouts. | | **Headers & Footers** | Yes | Yes | Yes | DOCX export writes all three variants — default, first-page (`w:titlePg`), and even-page (`word/settings.xml` with `w:evenAndOddHeaders`) — as `w:hdr`/`w:ftr` parts with full block content; ODT export writes them into the master page.

This makes picture bullets first-class in the model and renders them. - Model: `BulletChar::Image { src: String }` carries the bullet's image reference (a `data:` URI or part path). Serde/Loro round-trip is automatic. - Layout: since Parley cannot inline an image, the bullet is placed out-of-band. Extracted the list-marker synthesis from `flow_para` into a new `flow_list_marker` module; `synthesize` reports a picture bullet's `src` (and emits no marker glyph text), and `picture_bullet_item` builds a square image item sized to line 0, left-aligned in the hanging label box `[indent_start − label_w, indent_start]`, injected into the paragraph's items so it translates with the paragraph. (The extraction also dropped `flow_para` 741 → 710.) - `format_list_marker` returns an empty label for an image bullet (was `•`); the list inspector still labels it "Image bullet". Tested: `picture_bullet_emits_image_in_the_hanging_label_box` (end-to-end flow: the image carries the src, is a square within the label box, and sits one hanging-indent left of the wrapped text) + `format_marker_picture_bullet_has_no_text`. Import of the bullet image (OOXML `w:numPicBullet` / ODF `text:list-level-style-image`) follows in the next commits.
