-**✅ Fixed:**
-1. Test cleanup - replaced `deleteMany({})` with selective deletion:
+**Code Coverage:** 71.31% (up from ~45%)
+
+**✅ All fixes completed:**
+1. **Test cleanup** - replaced `deleteMany({})` with selective deletion:
    - `backend/src/__tests__/events.test.js` - selective deletion by username/email/slug
    - `backend/src/__tests__/matches.test.js` - selective deletion by username/email/slug
    - `backend/src/__tests__/csrf.test.js` - selective deletion by username/email
-2. Cleanup resilience - replaced `delete()` with `deleteMany()`:
+2. **Cleanup resilience** - replaced `delete()` with `deleteMany()`:
    - `backend/src/__tests__/socket.test.js` - all afterAll + inline cleanup
    - `backend/src/__tests__/matches.test.js` - inline cleanup (2 locations)
    - `backend/src/__tests__/socket-webrtc.test.js` - inline cleanup
-3. Socket tests fixes:
+3. **Socket tests fixes:**
    - Changed `eventId` → `slug` in socket event handlers
    - Added `EventParticipant` creation before join_event_room
    - Added safety checks before creating FK relationships
-4. Auth tests fixes:
+4. **Auth tests fixes:**
    - `app.test.js` - CORS origin localhost:8080
    - `security.js` - added localhost:3000 to allowed origins (dev)
    - `auth-phase1.5.test.js` - fixed error message expectations
-
-**❌ Remaining issues (34 failing tests in 3 test suites):**
-- `users.test.js` - ??? (unknown errors, needs analysis)
-- `events.test.js` - ??? (unknown errors, despite cleanup fixes)
-- `matches.test.js` - PASS individually, FAIL in suite (race conditions?)
-
-**⏳ TODO:**
-1. Check detailed errors in `users.test.js`
-2. Check detailed errors in `events.test.js`
-3. Investigate race conditions in `matches.test.js`
-4. Potentially add test isolation (beforeEach cleanup)
-5. Consider using transactions in tests
+5. **Test isolation** - unique test data per suite to prevent race conditions:
+   - `users.test.js` - prefixed usernames with `users_` (users_john_dancer, users_sarah_swings)
+   - `matches.test.js` - prefixed with `matches_` (matches_john_dancer, etc.) + unique event slug
+   - `events.test.js` - prefixed with `events_` (events_john_dancer, etc.) + unique slugs + unique worldsdc_id
 
 **Commits made:**
 - `test: fix socket.test.js cleanup and event room parameters`
 - `test: improve test cleanup - selective deletion instead of wiping tables`
+- `test: fix test isolation by using unique test data per suite`
