Route the surface metadata machine's authoritative `missing` (404) phase through the viewer's existing tombstone/advance path: an out-of-page delete (another tab, a job, the API) never crosses the process-local deletion bus, but where the header probes the shown image its HEAD returns `missing`, which is just as authoritative (DR-17). A sentinel + untrack keep the effect CONVE-1688-safe and terminating (a whole gone set cascades advance→advance→close, one 404 at a time). Only `missing` latches; a `transient` stays retryable. Fence `runToolbarAction` against the shown identity and reset `toolbarBusy`/ `toolbarError` on subject change, so a confirmed or slow delete of the shown image that races the advance can't strand "Deleting…" or an error on the survivor now on screen. Refresh the final-state comments: the viewer is now the second consumer of the shared action list; the viewer host carries live `mutationsEnabled` since C1 while the open channel stays permission-free; the deletion bus is process-local, and the missing path's probe-scope (strip images seed mime+size and aren't re-probed) is stated where it matters. Tests: missing→advance, missing-only→close, whole-set cascade→close, transient→ no-op, and shown-delete-while-confirm-up→clean-toolbar (mutation-verified against the reset).

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
