xarmian 90dadecb06 docs(web): the cold-path pin heals one of the eviction floor's four doors, not all four (TASK-2939) (#1290)
TASK-2920's `movedOutFloor` carried a paragraph saying the exposure its cap
leaves open would be closed by giving the cold path a cursor pin, at which
point "no per-id record is load-bearing at all", and that the pin was filed
rather than built. The pin shipped in d387d540 (IDEA-2924), which falsified
both halves of that paragraph and left the file telling the next reader the
mechanism does not exist.

Measured rather than reasoned: disabling `refusedByMovedOut` against the pin as
shipped fails seven of the ten legs in `localIndexMovedOutFloor.svelte.test.ts`.
The cold `/items-index` door is healed — it pins its cursor and replays the gap,
including ids whose floor the cap had already evicted. Two others cannot be,
because the eviction advances the cursor past itself in the same atomic write
and `ListMovedOutSince` is a `seq > since` query, so nothing re-delivers it:
`upsert` has no cursor and no replay at all (its other three guards are
resync-scoped or need an `existing` the hard evict removed), and the warm IDB
hydrate's reconcile drains from a `state.cursor` that same eviction advanced.
`resyncProjectionScope` fails too and is not counted: it pins as well, and the
leg asserts the end state before the replay its caller owns has run (CONVE-12).

Three further sites in the same class, all falsified by the pin's merge and
none swept at the time: `bootstrap`'s doc header and `applyDelta`'s doc both
asserted the cursor "only advances forward" (the first is now wrong outright,
the second is true only of that function's own writes), and
`localIndexInverseColdCheck.svelte.test.ts`'s header still described the cold
branch as keeping the higher cursor and never replaying. That header also now
says what the measurement showed about the file itself: with the floor disabled
all five of its legs still pass, so it no longer exercises the floor in any
load-bearing way and the sibling suite is where that coverage lives.

Comment-only. The floor stays; what changes is that these files now say which
door the pin covers and which two the floor is the last refusal for.

Pad Web UI

SvelteKit 2 + Svelte 5 frontend for Pad, compiled to static files and embedded into the Go binary.

Development

npm install
npm run dev          # Dev server at localhost:5173 (proxies API to localhost:7777)
npm run build        # Production build to build/
npm run check        # Type checking with svelte-check

When developing, run the Go backend separately with make dev from the project root.

Building for Production

Do not build in isolation. Always use make build from the project root — this builds the web frontend, then compiles the Go binary with the build output embedded via //go:embed.

Stack

  • Svelte 5 with runes ($state, $derived, $effect)
  • SvelteKit 2 with adapter-static (SPA mode)
  • Tiptap block editor with markdown round-trip
  • svelte-dnd-action for drag-and-drop in board/list views
  • SSE for real-time updates
  • TypeScript throughout
