+# Phase 8 Plan 1: Candidate Status Tracking Summary
+
+**Candidate status tracking (researching/ordered/arrived) with schema migration, service/Zod updates, 5 TDD tests, and clickable StatusBadge popup on CandidateCard**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-16T13:06:48Z
+- **Completed:** 2026-03-16T13:12:08Z
+- **Tasks:** 2
+- **Files modified:** 12
+
+## Accomplishments
+- Added `status` column to `thread_candidates` table with default "researching" and full Drizzle migration
+- Wired status through entire stack: schema, Zod validation, service CRUD, client type interfaces
+- Created StatusBadge component with clickable pill badge and popup menu (3 status options with icons)
+- Integrated StatusBadge into CandidateCard pill row with API mutation on status change
+- 5 new TDD tests covering all status CRUD operations (24 total thread service tests passing)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add status column and update backend + tests (TDD RED)** - `9342085` (test)
+2. **Task 1: Add status column and update backend + tests (TDD GREEN)** - `ca1c2a2` (feat)
+3. **Task 2: Create StatusBadge component and wire into CandidateCard** - `25956ed` (feat)
+
+_Note: Task 1 used TDD with separate RED and GREEN commits_
+
+## Files Created/Modified
+- `src/db/schema.ts` - Added status column to threadCandidates table
+- `src/shared/schemas.ts` - Added candidateStatusSchema Zod enum and status to createCandidateSchema
+- `src/server/services/thread.service.ts` - Status in getThreadWithCandidates select, createCandidate values, updateCandidate type
+- `src/client/hooks/useThreads.ts` - Added status to CandidateWithCategory interface
+- `src/client/hooks/useCandidates.ts` - Added status to CandidateResponse interface
+- `src/client/components/StatusBadge.tsx` - New clickable status badge with popup menu
+- `src/client/components/CandidateCard.tsx` - Added status and onStatusChange props, renders StatusBadge
+- `src/client/routes/threads/$threadId.tsx` - Passes status and useUpdateCandidate to CandidateCard
+- `tests/helpers/db.ts` - Added status column to test helper CREATE TABLE
+- `tests/services/thread.service.test.ts` - 5 new candidate status tests
+- `drizzle/0002_broken_roughhouse.sql` - Migration adding status column
+
+## Decisions Made
+- StatusBadge popup uses click-outside + Escape dismiss pattern matching CategoryPicker
+- Status badge uses muted gray tones (bg-gray-100 text-gray-600) per user design decision -- not semantic colors
+- Active status in popup menu highlighted with bg-gray-50 and checkmark icon
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Candidate status tracking fully operational
+- Ready for Plan 02 (search/filter functionality)
