PR #1007 (TASK-2131) added a PaneHost `$effect` that calls `paneOverlay.enter()`/`leave()` to inert the app-shell chrome behind the mobile detail-pane overlay. `enter()`'s `overlayCount += 1` READS `overlayCount` inside that tracked effect scope, so the effect took a reactive dependency on the very signal it writes: enter() dirtied the effect → it re-ran → enter()d again → `effect_update_depth_exceeded`. Svelte aborts the flush, stranding the rest of the subtree's reactivity — `paneMintForRoute` stopped recomputing, so the mobile pane (and its Back chevron) rendered EMPTY. The E2E `pane-controller` mobile-overlay tests caught it; #1007's own manual check verified the ARIA attributes but not that item content still rendered. Fix: `untrack` the count read in enter()/leave() so a write from an effect never establishes a self-dependency (the write still notifies the layout reader). The ref-count mutators are written from effects by design, so the untrack belongs in the store. Also fixes the second collision from the same #1007 change: the pane is now `role="dialog"` on mobile, so pane-controller.spec.ts:771's `[role="dialog"]` + text locator matched BOTH the pane and the BottomSheet (strict-mode violation). Target the sheet by accessible name ("Quick actions") instead — the pane's is "Item detail". The effect_update_depth_exceeded runaway only manifests under the real browser scheduler (not jsdom/vitest), so the E2E overlay tests own the loop regression; the unit tests lock the ref-count semantics.

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
