 #### Acceptance Criteria

-- [ ] Feature flag infrastructure in place
-- [ ] No changes to runtime behavior

+## Implementation Status Summary
+
+| Component | Status | Notes |
+|-----------|--------|-------|
+| Phase 0: Preparation | ✅ Complete | unified.ts schema created |
+| Phase 1-5: Migrations | ✅ Complete | All 22 tables created, data migrated |
+| Task 4: table-select.ts | ✅ Complete | UNIFIED_TABLES, getUnifiedTable(), boardTypeCondition() |
+| Task 5: Sync Functions | ✅ Complete | shared-sync.ts and user-sync.ts updated |
+| Task 6: Query Files | ✅ Complete | All query files updated to use unified tables |
+| Phase 6: Ascents/Bids Cleanup | ✅ Complete | Switched to boardsesh_ticks with NextAuth userId, legacy tables dropped |
+| Task 7: MoonBoard Storage | 📋 Planned | Server-side storage for MoonBoard climbs |
+| Phase 6b: Legacy Table Cleanup | 📋 Planned | Drop remaining legacy board-specific tables |
+
+### Phase 6 Key Decisions
+
+**Ascents/Bids Migration to boardsesh_ticks:**
+- All ascent and bid data now uses `boardsesh_ticks` table exclusively
+- Uses NextAuth `userId` (string) instead of Aurora `user_id` (integer)
+- Data not associated with NextAuth userId was accepted as droppable
+- Legacy tables (`kilter_ascents`, `kilter_bids`, `tension_ascents`, `tension_bids`) dropped via migration `0030_drop_legacy_ascents_bids.sql`
+- Removed `migrate-user-history.ts` and `/api/internal/migrate-users-cron` route (no longer needed)
