+# Phase 22 Plan 01: Add-to-Collection Flow Summary
+
+**AddToCollectionModal with category/notes/price fields, sonner toasts, and wired catalog search + detail page entry points**
+
+## Performance
+
+- **Duration:** 7 min
+- **Started:** 2026-04-06T13:49:46Z
+- **Completed:** 2026-04-06T13:57:00Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- Extended UIStore with addToCollectionModal, addToThreadModal, and catalogSessionThreadId states for full Phase 22 support
+- Built AddToCollectionModal following CreateThreadModal pattern with category dropdown, notes textarea, and purchase price input
+- Installed sonner and rendered Toaster at root layout for success feedback
+- Replaced handleAddStub in CatalogSearchOverlay with mode-aware dispatch to collection or thread modals
+- Added both "Add to Collection" (primary) and "Add to Thread" (secondary) buttons on global item detail page
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: UIStore extension + sonner setup + AddToCollectionModal** - `f309c73` (feat)
+2. **Task 2: Wire CatalogSearchOverlay and global item detail page for collection mode** - `ed76236` (feat)
+
+## Files Created/Modified
+- `src/client/components/AddToCollectionModal.tsx` - Modal with category, notes, purchase price; calls useCreateItem with globalItemId
+- `src/client/stores/uiStore.ts` - Added addToCollectionModal, addToThreadModal, catalogSessionThreadId states
+- `src/client/routes/__root.tsx` - Added Toaster and AddToCollectionModal to root layout
+- `src/client/components/CatalogSearchOverlay.tsx` - Replaced stub with mode-aware handleAdd dispatching to modals
+- `src/client/routes/global-items/$globalItemId.tsx` - Added "Add to Collection" and "Add to Thread" buttons wired to UIStore
+
+## Decisions Made
+- Used sonner for toast notifications (lightweight, accessible, clean styling)
+- Added all Phase 22 UIStore states in Task 1 so Plan 02 can consume addToThreadModal and catalogSessionThreadId immediately
+- closeCatalogSearch now resets catalogSessionThreadId to null for clean session state
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+- Service tests (item.service.test.ts, thread.service.test.ts) hang on execution -- pre-existing issue unrelated to client-side changes. Build verification confirms no type errors or regressions.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Plan 02 can immediately build AddToThreadModal consuming addToThreadModal and catalogSessionThreadId from UIStore
+- "Add to Thread" button on detail page already wired to openAddToThread
+- CatalogSearchOverlay already dispatches to openAddToThread in thread mode
