fix(sidepanel): resolve top 3 critique findings (P0 empty-state, P1 comparison, P1 FilterBar) - #270
Conversation
…ory to core The feed hero story's precedence rules (error vs offline vs broken sources vs new/priority vs empty) lived inline in FeedPage as a derived, making them untestable without mounting the whole page and conflating shell wiring with presentation logic. Extract `buildFeedStory` to `src/lib/core/feed/build-feed-story.ts` as a pure resolver (no I/O, no async, no Date.now()). Add a `hasCompletedScan` input to disambiguate the `scanned-empty` attention state from the pre-scan idle state (P0 from the side-panel critique: the hero previously could not tell "nothing matched" apart from "we haven't scanned yet"). Author `src/models/feed-story.model.md` as the presentation model of record (six states, strict precedence, copy decisions). FeedPage now imports the pure function; the operational-ui-constraints guard test is updated to assert the new-mission cue against the core module that now owns it. Tests: 30/30 in build-feed-story.test.ts. Typecheck + lint green. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
…st layout P1a from the side-panel critique: the comparison modal was overloaded — a 2×2 decision-evidence grid competed with the recommendation copy and buried the decision under technical detail. Collapse the default view to 5 high-signal rows (score, TJM + titles/stack), move 7 detail fields behind an "Afficher tous les détails" disclosure, and delete the redundant 2×2 grid entirely. The fused score now appears once in the table and once as a single compact DecisionEvidence chip inside the recommendation box (decision-first, unobtrusive). The disclosure toggle carries tabindex="-1" so it stays out of the modal focus-trap cycle — Tab from the close button still wraps to the first mission link (the trap relies on close being the last tab stop).

…toggle P1b from the side-panel critique: the FilterBar rendered an unbounded list of technology chips, overwhelming the bar when a scan surfaced dozens of stacks. Add pure ranking helpers in core (`rankStacksByCount`, `computeVisibleStacks`, `computeOverflowCount`) with stable alphabetical tiebreaks and selected-pinning. Surface `stackCounts`/`availableStacks` from the feed-page state, and render only the top-8 chips by frequency in FilterBar — any selected stack outside the top-8 stays pinned visible. An overflow toggle reveals the rest. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Persists the design critique (26/40, 1×P0 + 2×P1 + 2×P2) that drove the three follow-up fixes in this branch. Keeps the scoring rationale and heuristic findings alongside the implementation for future reference. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Pull request overview
This PR addresses the top 3 findings from the sidepanel $impeccable critique by extracting feed “hero story” resolution into the functional core (pure + unit-tested), distilling the mission comparison modal into a higher-signal default view with progressive disclosure, and bounding the FilterBar technology chips with overflow handling.
Changes:
- Extracted
buildFeedStoryintosrc/lib/core/feed/build-feed-story.tswith a newhasCompletedScandiscriminator and a presentation model (feed-story.model.md) + unit tests. - Refactored
MissionComparisonto show fewer default rows, move details behind a disclosure, and simplify decision evidence rendering. - Added pure stack ranking helpers and updated
FilterBar/feed-pagestate to rank stacks by frequency and render a top-N + overflow UI.

- FilterBar: computeOverflowCount now counts stacks in `availableStacks`
absent from the visible set, instead of `total - topN`. The old formula
overcounted when selected stacks were pinned outside the top-N (they are
already visible, so must not be reported as hidden overflow).
- MissionComparison: remove `tabindex="-1"` from the disclosure toggle so
it is keyboard-reachable. Update the focus-trap test to wrap from the
toggle (now the last tab stop) to the first mission link.
- feed-page: build stackCounts with Object.create(null) — stack names are
scraped from external pages, so a plain `{}` risks prototype pollution
via "__proto__"/"constructor" keys.

When active filters hide all cached missions, the empty-state story previously routed to "adjust profile" (and the primary-action handler navigated to the Profile page) even though the right fix was to clear filters. Adds a `filtered-empty` presentation state with higher precedence than `scanned-empty` in the `visibleCount === 0` bucket. Model updated (feed-story.model.md) as source of truth; resolver gains `filterActive` + `totalMissionCount` inputs; FeedPage wires them and the primary-action handler now clears filters for this case.

FeedPage.svelte called buildFeedStory() inside a $derived() in the instance
<script>, but only the <script module> block re-exported the symbol. A pure
re-export (export { X } from '...') does not create a binding accessible in the
instance scope, so the identifier was undefined at runtime. This threw
ReferenceError: buildFeedStory is not defined during FeedPage's initial
$derived evaluation, crashed the page, and blocked SearchInput from rendering,
which timed out expectFeedReady() and caused ~95 Browser E2E failures.
Fix: import buildFeedStory directly in the instance <script> and drop the
module-scope value re-export (only the test used it, and importing core logic
through a UI page was an anti-pattern). The test now imports from the core
source. Type re-exports are kept for any external consumers.
Verified: eslint, typecheck, 36 feed-story unit tests, 14 a11y E2E tests
(were timing out before the fix).

Summary
Acting on the
$impeccable critiqueofapps/extension/src/sidepanel(26/40; 1x P0 + 2x P1), this addresses the three highest-priority findings. All three follow the Model -> Review -> Implement -> Verify workflow, with new presentation logic extracted to the functional core so it is unit-testable without mounting the page.fix(feed)):buildFeedStorywas an inline derived inFeedPage, making its precedence rules (error vs offline vs broken sources vs new/priority vs empty) untestable and conflating shell wiring with presentation. Extracted tosrc/lib/core/feed/build-feed-story.tsas a pure resolver. Added ahasCompletedScaninput so the hero can distinguishscanned-empty("nothing matched") from the pre-scan idle state - the core ambiguity the critique flagged. Authoredsrc/models/feed-story.model.mdas the presentation model of record (six states, strict precedence).refactor(comparison)): collapsed the default view to 5 high-signal rows (score, TJM + titles/stack), moved 7 detail fields behind an "Afficher tous les details" disclosure, and deleted the redundant 2x2 evidence grid. The fused score now appears once in the table and once as a single compactDecisionEvidencechip inside the recommendation box. The disclosure toggle carriestabindex="-1"so it stays out of the modal focus-trap cycle (Tab from close still wraps to the first mission link).feat(filters)): added pure ranking helpers insrc/lib/core/filters/stack-ranking.ts(rankStacksByCountwith alphabetical tiebreak,computeVisibleStackswith selected-pinning,computeOverflowCount). FilterBar now renders the top-8 chips by frequency, with an overflow toggle for the rest; selected stacks outside the top-8 stay pinned visible.Verification
