+# Phase 6 Plan 3: Display Component Icon Migration Summary
+
+**Migrated all display components from emoji text to LucideIcon rendering with consistent sizing across cards, badges, and headers**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-03-15T16:53:10Z
+- **Completed:** 2026-03-15T16:59:16Z
+- **Tasks:** 2
+- **Files modified:** 13
+
+## Accomplishments
+- Replaced emoji text rendering with LucideIcon components in ItemCard, CandidateCard, ThreadCard, and ItemPicker
+- Updated all client-side hook interfaces from categoryEmoji to categoryIcon to match server API
+- Updated route files to pass icon prop to CategoryHeader and categoryIcon to card components
+- Removed old EmojiPicker.tsx and emojiData.ts files, zero emoji references remain
+- All 87 tests pass, build succeeds
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Update display components to use categoryIcon with LucideIcon** - `615c894` (feat)
+2. **Task 2: Update route files and delete old emoji files** - `9fcb07c` (chore)
+
+## Files Created/Modified
+- `src/client/components/ItemCard.tsx` - Renders LucideIcon at 36px in placeholder, 14px in badge
+- `src/client/components/CandidateCard.tsx` - Same LucideIcon pattern as ItemCard
+- `src/client/components/ThreadCard.tsx` - Renders LucideIcon at 16px next to category name
+- `src/client/components/ItemPicker.tsx` - Shows LucideIcon next to category group headers
+- `src/client/hooks/useItems.ts` - Interface: categoryEmoji -> categoryIcon
+- `src/client/hooks/useThreads.ts` - Interfaces: categoryEmoji -> categoryIcon in ThreadListItem and CandidateWithCategory
+- `src/client/hooks/useSetups.ts` - Interface: categoryEmoji -> categoryIcon
+- `src/client/hooks/useTotals.ts` - Interface: categoryEmoji -> categoryIcon
+- `src/client/hooks/useCategories.ts` - Mutation type: emoji -> icon
+- `src/client/lib/iconData.tsx` - Renamed from .ts to .tsx (contains JSX)
+- `src/client/routes/collection/index.tsx` - Passes icon to CategoryHeader, categoryIcon to cards
+- `src/client/routes/setups/$setupId.tsx` - Same icon prop updates
+- `src/client/routes/threads/$threadId.tsx` - Passes categoryIcon to CandidateCard
+
+## Decisions Made
+- Renamed iconData.ts to iconData.tsx since it contains JSX and the production build (rolldown) requires proper .tsx extension for JSX parsing
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Updated client hook interfaces to match server API**
+- **Found during:** Task 1 (display component updates)
+- **Issue:** Client-side TypeScript interfaces in hooks still referenced categoryEmoji but server API returns categoryIcon after Plan 01 migration
+- **Fix:** Updated interfaces in useItems, useThreads, useSetups, useTotals, and useCategories hooks
+- **Files modified:** 5 hook files
+- **Verification:** Build succeeds, types match API responses
+- **Committed in:** 615c894 (Task 1 commit)
+
+**2. [Rule 1 - Bug] Renamed iconData.ts to iconData.tsx**
+- **Found during:** Task 1 (build verification)
+- **Issue:** iconData.ts contains JSX (LucideIcon component) but had .ts extension, causing rolldown parse error during production build
+- **Fix:** Renamed file to .tsx
+- **Files modified:** src/client/lib/iconData.tsx (renamed from .ts)
+- **Verification:** Build succeeds
+- **Committed in:** 615c894 (Task 1 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (1 blocking, 1 bug)
+**Impact on plan:** Both fixes necessary for build correctness. No scope creep.
+
+## Issues Encountered
+- Plan 02 (IconPicker + component updates) had partial uncommitted work in the working tree. The CategoryHeader, CategoryPicker, OnboardingWizard, and CreateThreadModal were already updated to use icon/IconPicker. These changes were committed as part of the pre-commit flow.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Category icon migration is complete across all layers: database, API, and UI
+- All components render Lucide icons consistently
+- Phase 6 is fully complete
+
+## Self-Check: PASSED
+
+All created files verified, all commits found, zero emoji references confirmed.
