+# Phase 6 Plan 1: Category Icon Data Layer Summary
+
+**Migrated categories from emoji to Lucide icon names with curated 119-icon data set and LucideIcon render component**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T16:45:02Z
+- **Completed:** 2026-03-15T16:50:15Z
+- **Tasks:** 2
+- **Files modified:** 18
+
+## Accomplishments
+- Renamed emoji column to icon across DB schema, Zod schemas, and all 5 services
+- Created Drizzle migration with emoji-to-icon data conversion for existing categories
+- Built iconData.ts with 119 curated gear-relevant Lucide icons across 8 groups
+- Added LucideIcon component with kebab-to-PascalCase conversion and Package fallback
+- All 87 tests pass, build succeeds
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Migrate schema, Zod schemas, services, test helper, and seed to icon field** - `546dff1` (feat)
+2. **Task 2: Install lucide-react and create icon data file with LucideIcon component** - `fca1eb7` (feat)
+
+## Files Created/Modified
+- `src/db/schema.ts` - Categories table now uses icon column with "package" default
+- `src/shared/schemas.ts` - Zod schemas validate icon as string(1-50)
+- `src/server/services/category.service.ts` - Parameter types use icon instead of emoji
+- `src/server/services/item.service.ts` - Returns categoryIcon instead of categoryEmoji
+- `src/server/services/thread.service.ts` - Returns categoryIcon in both list and detail
+- `src/server/services/setup.service.ts` - Returns categoryIcon in setup item list
+- `src/server/services/totals.service.ts` - Returns categoryIcon in category totals
+- `src/db/seed.ts` - Seeds Uncategorized with icon "package"
+- `tests/helpers/db.ts` - Test helper creates icon column, seeds with "package"
+- `src/client/lib/iconData.ts` - Curated icon groups, LucideIcon component, emoji-to-icon map
+- `drizzle/0001_rename_emoji_to_icon.sql` - Migration SQL with data conversion
+- `package.json` - Added lucide-react dependency
+
+## Decisions Made
+- Used ALTER TABLE RENAME COLUMN for SQLite migration -- simpler than table recreation, supported in SQLite 3.25+
+- Applied migration directly via Bun SQLite API since drizzle-kit push/generate requires interactive input for column renames
+- Included 119 icons (slightly under the upper bound) for comprehensive gear coverage without bloat
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Updated all test files referencing emoji/categoryEmoji**
+- **Found during:** Task 1 (schema migration)
+- **Issue:** Test files referenced emoji field and categoryEmoji property which no longer exist after schema rename
+- **Fix:** Updated 6 test files to use icon/categoryIcon
+- **Files modified:** tests/services/category.service.test.ts, tests/routes/categories.test.ts, tests/services/item.service.test.ts, tests/services/totals.test.ts, tests/services/setup.service.test.ts, tests/services/thread.service.test.ts
+- **Verification:** All 87 tests pass
+- **Committed in:** 546dff1 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 blocking)
+**Impact on plan:** Test updates were necessary for correctness. No scope creep.
+
+## Issues Encountered
+- drizzle-kit generate/push commands require interactive input for column renames -- applied migration SQL directly via Bun SQLite API instead
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Icon data infrastructure complete, ready for UI component work (06-02: IconPicker, 06-03: display integration)
+- Client-side still references categoryEmoji -- will be updated in subsequent plans
+
+## Self-Check: PASSED
+
+All created files verified, all commits found, all key exports confirmed.
