TASK-2433 made the inline-image activation path resolve the attachment's
MIME before emitting and refuse anything not positively allowlisted. That
refusal was binary: `ok` + raster opened the viewer and every other result
returned silently, leaving two states where a focused, button-announced
image swallowed the gesture — a `transient` probe, and a resolved MIME the
viewer will not take.
This completes the four-branch matrix, each arm with a destination:
- `ok` + allowlisted raster → the viewer, unchanged.
- `ok` + anything else → the options PANEL (DR-7). A REDIRECT, not a
refusal: an SVG or a PDF referenced as an inline image is a real
attachment with real options, it is just not something to hand a viewer
that would execute it. The image therefore stays a real activation
target and its accessible name names the panel — taking the semantics
off (as the binary gate did) would hide a working control, and would
make the redirect fire exactly once before the recorded MIME closed the
gate on every later tap.
- `missing` (authoritative 404) → the permanent placeholder, latched,
nothing opened.
- `transient` → the RETRYABLE placeholder. Never an open and never a
latch: only a 404 is authoritative (DR-17).
The fence is hardened to the FULL address. The whole address is captured
before the await and compared after, and both emissions stamp the CAPTURED
values — the reader is live (`CommentEditor` is reused across an item
switch) so a re-read can address the wrong host. The continuation also
re-checks `deleted` on its own terms: a delete does not change which
attachment the node points at, so a probe issued before it can resolve `ok`
afterwards with the uuid still current. Check and emit stay adjacent and
synchronous — no timer, no microtask between them.
Also adds the minimal pending contract the await needs: `aria-busy` plus a
wait cursor while the MIME resolves, cleared by the resolution's finalizer
and by a uuid swap. No new chrome.
Seam with PLAN-2411, stated in comments and deliberately not built: the
`deleted` latch is cleared ONLY by an authoritative restore signal on
2411's channel, never by editor undo — DR-17 requires Ctrl-Z to leave an
inert placeholder rather than resurrect a working attachment.

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
