spaces: reach the whole view block, and export what a board actually holds

[nyblnet]

Two of the gaps from the audit, fixed.

The view controls

layout: 'list' has rendered since the tracker shipped and nothing in the app could produce one — a view could hold a layout you could not undo — and groupBy was reachable only by hand-editing JSON. Board ⇄ List, Group and Sort now sit beside Open only and Filter, all inside the same opts.editable guard, so a reader and a printout still get none of them.

Sort — settling what the decision log deferred

DECISIONS.md said a stored sort and a hand-dragged order contradict each other, and that whoever needed sort had to settle which wins first.

They don't contradict. The hand order is doc.pages; the sort is a key on one block; sorting touches neither. So a sort overrides for as long as it's there, and clearing it returns the exact arrangement. "Manual order" is the first item in the menu — it's the absence of a sort, not a sort called manual.

What sorting does cost is the positional drop. With an order in force, a drop position would write into doc.pages an order the next paint discards — a gesture that appears to do nothing and leaves an undo step behind. The column still highlights and still takes the card; only the insertion point stops being offered.

Ordering rules, each of which is silently wrong the other way:

• a select sorts by its declared order — alphabetising "Backlog, Todo, In progress, Done" throws away the only thing the list was saying
• an unset value sorts last in both directions — a blank estimate is not the cheapest issue
• a value a newer build wrote sorts after everything this build knows, rather than leading a board with a status nobody here can read
• ties keep the page order, so a hand-arranged board still reads that way within each band
• an unknown sort key is skipped and the view says so

sort is an array holding one entry — the shape already published — because a second key can be added later, where widening a scalar afterwards could not be done at all.

The export

Every prop block carries a readable Status: In progress. That string is the whole reason the format degrades instead of vanishing for an older build, a thumbnailer or a grep — and the Markdown exporter, its most important consumer, wrote **status:** doing from right beside it, publishing the internal option id to the one audience with no schema to look it up in.

A board exported as its own italic title and nothing else, so a tracker downloaded as Markdown showed a heading where the work was. Boards now export their issues — grouped as the board groups them, in column order, each a link back to its page, carrying the same chips the card shows — with the same filter and sort the screen is using.

toMd's fourth parameter became an MdCtx so a block that describes other content can ask about it, rather than growing a second traversal that drifts from the app.

Measured in the built shell, not asserted

• the layout button switches, and Group disappears for a list (a list has no columns)
• sorting by priority gives Urgent → High → Medium → the two with none; clicking the same field reverses it
• Manual order deletes the key, leaving the block byte-identical to how the starter wrote it
• a dragover on a sorted column marks the column and no position; the same dragover unsorted marks the position — a negative control that fires
• the exported Markdown was captured from the real download path

Size

+3.4 KB compressed → 135,134 B, which was 100.0% of the old ceiling. The ceiling moves to 138 KiB in this commit with the reason recorded beside it, per the rule the size gate states.

Rigs

412/412 model (up from 392), 143/143 agent, 18/18 undo, 40/40 release, i18n 234 × 8 complete, splice conformance gate.

One existing assertion was rewritten rather than repaired: it pinned the view controls to the first statement inside the editable guard, so adding a control above it broke the test without breaking anything — and adding one below the guard would have broken the app without breaking the test. It now checks that every control name appears inside the guard and nowhere else.

DECISIONS.md carries the settlement, and the deferral above it is marked settled and points at it. spaces/README.md no longer lists databases as unbuilt.
