xarmian af24997c72 fix(web): re-resolve the follow target by id at fire time (BUG-2848)
Codex round 1, P2, and a real latent bug in the previous commit. Capturing the
item OBJECT and reusing it 140ms later keeps a stale snapshot: a rename during
the debounce changes the slug, `openItemPane` builds the URL from that slug, and
the id-only existence check passes happily on the way to a dead URL.

What is captured is now the IDENTITY — `targetId` — and the callback re-resolves
the current row from `filteredItems` before opening it. That still follows a row
that MOVED, which is the whole point of the fix, and still skips one that was
DELETED, while picking up any change to the row itself.

Also answering the round's second P2 in the spec rather than in code: the race
is probabilistic and cannot be made deterministic without a seam in the page.
The asymmetry is what makes that acceptable, and it is now written down — a
round that misses the 140ms window still PASSES on a correct build, because the
cursor moves, the pane follows and the intended row is where it should be. So
missing costs power, not correctness; the failure mode is a false green, never a
false red. Three rounds put a false green around 1 in 1700 against a build that
loses the keypress 11 times in 12.

pane-follow-live-list + pane-controller: 44/44 across both projects.

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
