The July audit's share-page broken-image finding was fixed by BUG-2389 and
TASK-2637: the share byte endpoint serves variants of attachments the
shared item OWNS. What was left: an image uploaded with
`pad attachment upload -` (item_id NULL) and then embedded is never owned,
so its share shows the placeholder. A census of this workspace found 4
such refs out of 13, all from that path.
Lead ruling (option C): fix it explicitly, with no implicit binding on
content writes.
- POST /workspaces/{ws}/attachments/{id}/attach {item}. It binds a live,
unattached original in this workspace, and its live variants, to an
item. Every UPDATE requires item_id IS NULL, so an attached row is never
moved, and the bind is exclusive with the never-attached GC claim. The
item is pinned like CreateAttachmentForLiveItem.
- Authorization: the caller can see and edit the item, and uploaded the
attachment or is a workspace owner. An attached row answers 409 to a
caller who can see its owner, and the shared 404 to anyone else.
Restricted members and guests cannot read unattached rows, so they get
the 404. That closes the case where a guest binds an id they know to an
item they can edit and publishes it through its share.
- The attachment_attach capability. `pad attachment attach <id> <item-ref>`
refuses against a server that does not advertise it, because an older
build's bare 404 would read as "attachment not found".
- The `upload -` help text, the attachment group help, both skill copies
and CLAUDE.md say an unattached image does not render on share pages.
- No MCP surface: pad_attachment has no upload.
Tests: 12 server/store tests, including an end-to-end share leg (404
before, variant bytes after), and 9/9 mutants killed. CLI capability
gate: 2 tests, mutant killed. e2e: the share renders the image after
attach; with attach made a no-op it goes red at "attached: no
placeholder".

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
