+# Phase 6 Plan 2: Category Icon UI Components Summary
+
+**IconPicker component with search/group tabs and all category create/edit/display flows migrated from emoji to Lucide icons**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T16:53:11Z
+- **Completed:** 2026-03-15T16:58:04Z
+- **Tasks:** 2
+- **Files modified:** 9
+
+## Accomplishments
+- Created IconPicker component with portal popover, search filtering, 8 group tabs, and 6-column icon grid
+- Replaced EmojiPicker with IconPicker in CategoryPicker, CategoryHeader, and OnboardingWizard
+- Updated CategoryPicker to show LucideIcon prefix in input and dropdown list items
+- Build succeeds with no TypeScript errors
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create IconPicker component** - `59d1c89` (feat)
+2. **Task 2: Update CategoryPicker, CategoryHeader, OnboardingWizard, and CreateThreadModal** - `570bcea` (feat)
+
+## Files Created/Modified
+- `src/client/components/IconPicker.tsx` - New portal-based Lucide icon picker with search and group tabs
+- `src/client/components/CategoryPicker.tsx` - Uses IconPicker for inline create, LucideIcon for display
+- `src/client/components/CategoryHeader.tsx` - LucideIcon in view mode, IconPicker in edit mode
+- `src/client/components/OnboardingWizard.tsx` - IconPicker for category creation step
+- `src/client/components/CreateThreadModal.tsx` - Removed emoji from category select options
+- `src/client/hooks/useCategories.ts` - Fixed emoji -> icon in useUpdateCategory type
+- `src/client/routes/collection/index.tsx` - Fixed categoryEmoji -> categoryIcon references
+- `src/client/routes/setups/$setupId.tsx` - Fixed categoryEmoji -> categoryIcon references
+- `src/client/routes/threads/$threadId.tsx` - Fixed categoryEmoji -> categoryIcon reference
+
+## Decisions Made
+- Native HTML `<select>` elements cannot render React components, so category select dropdowns show name only (no icon prefix)
+- IconPicker uses 6-column grid instead of EmojiPicker's 8-column for better visibility of icons at 20px
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Fixed categoryEmoji -> categoryIcon in collection and setup routes**
+- **Found during:** Task 2
+- **Issue:** Routes passed `emoji={categoryEmoji}` to CategoryHeader and used `item.categoryEmoji` which no longer exists after Plan 01 renamed the field
+- **Fix:** Updated all `categoryEmoji` references to `categoryIcon` and `emoji=` prop to `icon=` in collection/index.tsx, setups/$setupId.tsx, and threads/$threadId.tsx
+- **Files modified:** src/client/routes/collection/index.tsx, src/client/routes/setups/$setupId.tsx, src/client/routes/threads/$threadId.tsx
+- **Verification:** Build succeeds
+- **Committed in:** 570bcea (Task 2 commit)
+
+**2. [Rule 3 - Blocking] Fixed useUpdateCategory hook type from emoji to icon**
+- **Found during:** Task 2
+- **Issue:** useUpdateCategory mutationFn type still had `emoji?: string` instead of `icon?: string`
+- **Fix:** Changed type to `icon?: string`
+- **Files modified:** src/client/hooks/useCategories.ts
+- **Verification:** Build succeeds
+- **Committed in:** 570bcea (Task 2 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 blocking)
+**Impact on plan:** Both fixes were necessary for build to pass after Plan 01 renamed emoji to icon. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- IconPicker and all category create/edit components complete
+- EmojiPicker.tsx and emojiData.ts can be removed in Plan 03 (cleanup)
+- Some display components (ItemCard, ThreadCard, etc.) were already updated in Plan 01
