* feat: seq-stamped SSE events + stale-event short-circuit (TASK-1358)
## Server
- events.Event gains a `Seq int64` field (omitempty). Server populates
it on item lifecycle events so SSE consumers can reason about
ordering and contiguity against their /items-changes cursor.
- publishItemEventWithName takes seq as a parameter; all call sites
in handlers_items.go pass the item's current seq:
- item_created → item.Seq
- item_updated → updated.Seq
- item_archived → re-fetched via GetItemIncludeDeleted (DeleteItem
bumps seq but doesn't return the updated row)
- item_restored → restored.Seq
- move target → moved.Seq
## Web
- ItemEvent gains optional `seq` (matches the server's omitempty).
- localIndex.classifySSEEvent(ws, event) returns
'no-seq' | 'stale' | 'contiguous' | 'gap'. The collection page
uses this to short-circuit duplicate / replayed events the
server's replay buffer re-delivers after tab-resume. Non-stale
events still call deltaSync because the SSE wire payload only
carries metadata, not the row data; classify does NOT advance
the cursor (applyDelta with real row data is the only path that
does — preserving the IDB invariant from TASK-1356).
Parent: PLAN-1343.
* fix(events): version-restore item_updated event carries seq (Codex round 1)
Version-restore in handlers_item_versions.go was publishing the
item_updated event directly via events.Publish without Seq, bypassing
the new seq-stamped SSE contract from TASK-1358. localIndex's
classifySSEEvent would always return 'no-seq' for those events,
forcing a generic /items-changes refetch instead of allowing the
stale/gap fast paths.
Now passes updated.Seq from the store response.
Parent: PLAN-1343.
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
