3c-ii T4b: with every producer already on the surface channel (T4a), delete
the two legacy channels and the cutover-window bridge. Gone from
`events.ts`: `notifyViewerOpen`, `notifyAttachmentPanelOpen`,
`ViewerReadyImage`, `ViewerOpenRequest`, `AttachmentViewerOpenEvent`,
`AttachmentPanelOpenEvent`, both legacy predicates
(`isAttachment{Viewer,Panel}EventForHost`) and registries
(`registerAttachment{Viewer,Panel}Listener`), plus the producer-boundary
MIME-drop gate (it lived inside `notifyViewerOpen`). The surface channel —
no admission MIME gate, renderer arm decides — is the sole open channel.
`AttachmentSurfaceHost` loses its two legacy subscriptions and the
`fromPanel` / `fromViewer` translators, and its `wsSlug` prop retires (the
surface channel captures its own workspace at emit); `ItemDetail` stops
passing it. The now-dead viewer-toolbar context props left by T4a
(`mutationsEnabled` / `getItemContent` / `getLiveContent`) delete from
`ItemAttachmentStrip` and `ItemTimeline` — the host forwards them to
`Lightbox` directly. Stale `AttachmentViewerHost` / panel-channel comments
updated across the touched files.
Tests: the legacy-channel unit + bridge tests delete with the channel; the
three host tests that exercised real surface behavior through a legacy event
re-point onto the surface channel (and the invoker + one-probe tests gain
discriminating assertions). Full suite green (1357), `npm run check` 0 errors.
Reviewed to a fresh-angle CLEAN over four Codex rounds.

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
