+  - Added `competitorNumber` field to EventParticipant model
+  - Optional string field for bib/competitor number

+## ✅ Recording Matching System (COMPLETED 2025-11-22)
+
+**Status:** Completed
+**Time Spent:** ~4 hours
+**Commits:** 3 commits
+
+### Overview
+Auto-matching system that pairs dancers with recorders for video capture during competitions. The algorithm considers:
+- Heat collision avoidance (can't record while dancing)
+- Schedule config for division slot collision groups
+- Buffer time (1 heat after dancing before can record)
+- Location preference (same city > same country > anyone)
+- Max recordings per person limit (3)
+
+### Backend Implementation
+- [x] ✅ **Matching service** `backend/src/services/matching.js`
+  - `runMatching(eventId)` - Main algorithm
+  - `buildDivisionSlotMap()` - Parse schedule config
+  - `getTimeSlot()` - Calculate slot identifier
+  - `getBufferSlots()` - Buffer after dancing
+  - `hasCollision()` - Check availability
+  - `getCoverableHeats()` - Find recordable heats
+  - `getLocationScore()` - Preference scoring
+  - `saveMatchingResults()` - Persist suggestions
+  - `getUserSuggestions()` - Get user's assignments
+- [x] ✅ **RecordingSuggestion model**
+  - Links heat to suggested recorder
+  - Status: pending, accepted, rejected, not_found
+- [x] ✅ **Schedule config** in Event model
+  - JSON field for slot configuration
+  - Divisions in same slot collide with each other
+- [x] ✅ **API endpoints** in events.js
+  - `POST /api/events/:slug/matching/run` - Run matching algorithm
+  - `GET /api/events/:slug/matching/suggestions` - Get user suggestions
+
+### Frontend Implementation
+- [x] ✅ **RecordingTab component**
+  - "To Be Recorded" section (heats where user needs recorder)
+  - "To Record" section (heats where user records someone)
+  - Suggestion status indicators
+  - Accept/decline actions
+
+### Constants
+- [x] ✅ **SUGGESTION_STATUS** - pending, accepted, rejected, not_found
+- [x] ✅ **SUGGESTION_TYPE** - toBeRecorded, toRecord
+
+### Git Commits
+1. `feat(matching): add auto-matching system for recording partners`
+2. `feat(frontend): add recording matching UI`
+3. `feat(matching): add schedule config for division collision groups`

+## ✅ Frontend Refactoring (COMPLETED 2025-11-23)
+
+**Status:** Completed
+**Commits:** 6 commits
+
+### Overview
+Major refactoring of frontend code to extract reusable components and add status constants for better code quality.
+
+### Component Extraction
+- [x] ✅ **DashboardPage** extracted into:
+  - `DashboardHeader.jsx`
+  - `EventCard.jsx`
+  - `MatchCard.jsx`
+  - `MatchRequestCard.jsx`
+  - Barrel export: `components/dashboard/index.js`
+- [x] ✅ **EventDetailsPage** extracted into components
+- [x] ✅ **ProfilePage** extracted into:
+  - `ProfileForm.jsx` (192 lines)
+  - `PasswordChangeForm.jsx` (99 lines)
+  - Reduced ProfilePage from 394 → 84 lines (-79%)
+- [x] ✅ **MatchesPage** extracted:
+  - `MatchCard.jsx` component
+  - Barrel export: `components/matches/index.js`
+
+### Status Constants
+- [x] ✅ **Frontend** `frontend/src/constants/statuses.js`
+  - `MATCH_STATUS` - pending, accepted, rejected, completed
+  - `SUGGESTION_STATUS` - pending, accepted, rejected, not_found
+  - `MATCH_FILTER` - all, pending, accepted
+  - `CONNECTION_STATE` - disconnected, connecting, connected, failed
+  - `SUGGESTION_TYPE` - toBeRecorded, toRecord
+- [x] ✅ **Backend** `backend/src/constants/statuses.js`
+  - `MATCH_STATUS` - Same values as frontend
+  - `SUGGESTION_STATUS` - Same values as frontend
+- [x] ✅ Updated all files to use constants instead of string literals
+
+### Test Fixes
+- [x] ✅ **users.test.js** - Added wsdcId cleanup for unique constraint
+- [x] ✅ **auth-phase1.5.test.js** - Added wsdcId cleanup with related data deletion
+- [x] ✅ All 286 backend tests passing
+
+### Git Commits
+1. `refactor(frontend): extract EventDetailsPage into components`
+2. `refactor(frontend): extract DashboardPage into components`
+3. `refactor(frontend): extract MatchCard component from MatchesPage`
+4. `refactor(frontend): extract ProfileForm and PasswordChangeForm from ProfilePage`
+5. `refactor(frontend): replace status string literals with constants`
+6. `refactor(frontend): add CONNECTION_STATE and SUGGESTION_TYPE constants`
+7. `refactor(backend): add status constants and update code to use them`
+8. `fix(tests): add wsdcId cleanup to prevent unique constraint violations`
