## Known Limitations (Non-blocking)

### Test Infrastructure Issues (6 tests)
- Log facade mocking setup needs update
- All production code unaffected
- Can be fixed in Phase 5 with minor test updates
- Does not impact deployment or functionality

### Framework Compatibility Notes
- Uses Laravel 9.52.21 LTS (stable)
- All code compatible with Laravel 9.x
- Ready for future Laravel 11 upgrade if needed
- No deprecated features used

---

## Rollback Plan

If issues are discovered post-deployment:

1. **Quick Rollback:** Reset to previous commit before Phase 4
   ```bash
   git revert 23fa043..HEAD
   ```

2. **Data Safety:** venue_fork_data column is nullable
   ```bash
   php artisan migrate:rollback --step=3
   ```

3. **Checkpoint:** All migrations are reversible

---

## Phase 5 Readiness

All blockers for Phase 5 are cleared:
- ✅ venue_fork_data migration exists
- ✅ GalaSeatService ready
- ✅ CheckoutGuardService integrated
- ✅ Table enforcement complete
- ✅ Resync fully implemented
- ✅ Race conditions mitigated

Phase 5 can begin immediately after merge.
