+# Phase 21 Plan 03: Card Navigation Rewire & Panel Removal Summary
+
+**All card components rewired from slide-out panels to detail page navigation, panels removed from root layout, UIStore cleaned of panel state**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-04-06T13:04:59Z
+- **Completed:** 2026-04-06T13:11:00Z
+- **Tasks:** 2
+- **Files modified:** 10
+
+## Accomplishments
+- ItemCard, CandidateCard, CandidateListItem all navigate to detail pages on click using TanStack Router useNavigate
+- CatalogSearchOverlay cards navigate to /global-items/:id (closing overlay first), with Add button using stopPropagation
+- Slide-out panel JSX and imports completely removed from __root.tsx
+- UIStore cleaned of 11 panel-related properties/actions while preserving all dialog, FAB, and catalog search state
+- All downstream references (CollectionView, ItemForm, CandidateForm, thread page) updated to remove dead panel references
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Rewire card click handlers to navigate to detail pages** - `1f79c5c` (feat)
+2. **Task 2: Remove slide-out panels from root layout and clean UIStore** - `4c79735` (feat)
+
+## Files Created/Modified
+- `src/client/components/ItemCard.tsx` - Navigate to /items/$itemId instead of openEditPanel
+- `src/client/components/CandidateCard.tsx` - Navigate to /threads/$threadId/candidates/$candidateId
+- `src/client/components/CandidateListItem.tsx` - Navigate to candidate detail page
+- `src/client/components/CatalogSearchOverlay.tsx` - Card click navigates to /global-items/$globalItemId
+- `src/client/routes/__root.tsx` - Removed both SlideOutPanel instances and all panel state reads
+- `src/client/stores/uiStore.ts` - Removed panel state/actions, kept dialogs and other state
+- `src/client/components/CollectionView.tsx` - Empty state button uses catalog search instead of add panel
+- `src/client/components/ItemForm.tsx` - Replaced closePanel with onClose prop
+- `src/client/components/CandidateForm.tsx` - Replaced closeCandidatePanel with onClose prop, removed UIStore import
+- `src/client/routes/threads/$threadId.tsx` - Replaced openCandidateAddPanel with local state
+
+## Decisions Made
+- Preserved currentThreadId derivation block in __root.tsx because CandidateDeleteDialog depends on it (checker flagged this)
+- CollectionView empty state Add button rewired to open catalog search overlay rather than the removed add panel
+- ItemForm and CandidateForm given onClose prop to decouple from UIStore panel actions (forms still exist on disk per plan requirement)
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Updated CollectionView.tsx to remove dead openAddPanel reference**
+- **Found during:** Task 2 (panel cleanup)
+- **Issue:** CollectionView referenced openAddPanel which was removed from UIStore
+- **Fix:** Replaced with openCatalogSearch("collection") to maintain "Add Item" functionality via catalog
+- **Files modified:** src/client/components/CollectionView.tsx
+- **Verification:** grep confirms no dead references remain
+- **Committed in:** 4c79735 (Task 2 commit)
+
+**2. [Rule 3 - Blocking] Updated threads/$threadId.tsx to remove dead openCandidateAddPanel reference**
+- **Found during:** Task 2 (panel cleanup)
+- **Issue:** Thread page referenced openCandidateAddPanel which was removed from UIStore
+- **Fix:** Replaced with local useState (Plan 02 already restructured this file with a proper modal)
+- **Files modified:** src/client/routes/threads/$threadId.tsx
+- **Verification:** grep confirms no dead references remain
+- **Committed in:** 4c79735 (Task 2 commit)
+
+**3. [Rule 3 - Blocking] Updated ItemForm.tsx and CandidateForm.tsx to remove dead panel close references**
+- **Found during:** Task 2 (panel cleanup)
+- **Issue:** Forms referenced closePanel/closeCandidatePanel which were removed from UIStore
+- **Fix:** Added onClose prop to both forms, replaced store calls with onClose?.()
+- **Files modified:** src/client/components/ItemForm.tsx, src/client/components/CandidateForm.tsx
+- **Verification:** grep confirms no dead references remain
+- **Committed in:** 4c79735 (Task 2 commit)
+
+---
+
+**Total deviations:** 3 auto-fixed (3 blocking)
+**Impact on plan:** All auto-fixes necessary to prevent broken references after panel state removal. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Known Stubs
+None - all navigation targets exist (created by Plans 01 and 02), no placeholder data.
+
+## Next Phase Readiness
+- All cards navigate to detail pages, panel-to-page migration complete
+- Phase 21 complete: item detail pages, candidate detail pages, and navigation rewiring all done
+- Ready for Phase 22 (next milestone work)
