═══════════════════════════════════════════════════════════════════════════════
7️⃣ INTEGRATION STEPS
═══════════════════════════════════════════════════════════════════════════════

In server.dart, REPLACE THIS (old):
┌──────────────────────────────────────────────────────────────┐
│ import 'services/recording_scheduler.dart';                 │
│ final recordingScheduler = RecordingScheduler(db);          │

│                                                             │
│ Future<void> _injectPlaylistToScheduler() async {           │
│   final users = db.getAllUsers();                           │
│   if (users.isNotEmpty) {                                   │
│     // ... 25 lines of complex playlist injection           │
│   }                                                         │
│ }                                                           │
│ Future.delayed(Duration(seconds: 5), _inject...);          │
│                                                             │
│ router.post('/api/recordings', recordingsApi.handlePost);  │
│ router.get('/api/recordings', recordingsApi.handleGetAll); │
│ router.delete('/api/recordings/<id>', ...);                │
│ // ... 3+ more endpoint setups                             │
└──────────────────────────────────────────────────────────────┘

WITH THIS (new):
┌──────────────────────────────────────────────────────────────┐
│ import 'services/simple_recorder.dart';                     │
│ final recorder = SimpleRecorder(db);                        │
│ await recorder.init();                                      │
│                                                             │
│ Timer.periodic(Duration(minutes: 1),                        │
│   (_) => recorder.checkScheduled());                        │
│                                                             │
│ Timer.periodic(Duration(hours: 6),                          │
│   (_) => recorder.cleanupOld());                            │
│                                                             │
│ final recordingApi = SimpleRecordingApi(db, recorder);      │
│ router.mount('/api/record/', recordingApi.router);         │
└──────────────────────────────────────────────────────────────┘

═══════════════════════════════════════════════════════════════════════════════
8️⃣ COMPATIBILITY
═══════════════════════════════════════════════════════════════════════════════

✅ Database: FULLY COMPATIBLE (same tables)
✅ Old Recordings: PRESERVED (still readable)
✅ File Storage: SAME (/app/recordings/)
✅ API: DROP-IN REPLACEMENT (different endpoints though)
✅ FFmpeg: SAME (uses native FFmpeg)
⚠️  Season Passes: REMOVED (use Schedule instead, simpler!)

═══════════════════════════════════════════════════════════════════════════════
9️⃣ VALIDATION CHECKLIST
═══════════════════════════════════════════════════════════════════════════════

Before Integration:
  ☐ Remove old files (5 files)
  ☐ Add new files (3 files)
  ☐ Update server.dart (5 lines)
  ☐ Update imports

After Integration:
  ☐ Test: Record NOW (2 min duration)
  ☐ Test: Schedule (5 min in future)
  ☐ Test: Stop recording
  ☐ Test: List all recordings
  ☐ Test: View active
  ☐ Check /app/recordings/ for files
  ☐ Check auto-cleanup (6 hours later)

═══════════════════════════════════════════════════════════════════════════════
