# 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
