  - Game loop: `initLifeSim()` - Core game tick engine

**Key Server Functions:**
- `async handler(websocket)` - Main connection handler
- `async consumer(message, websocket)` - Message router from clients
- `async producer(websocket)` - Server updates to clients
- `async initLifeSim(websocket, oneTimePlayer=False)` - Game state progression
- `async main()` - Server startup (runs on port 8001)
- `async iterateGames()` - Background player iteration for disconnected players
- `async every_minute()` - Scheduled tasks executed every minute

**Supporting Core Files:**
- `functions.py` (2,862 lines) - Game state management, database operations, player logic
- `events.py` (1,238 lines) - Game event system and event firing
- `dayEvents.py` - Daily scheduled events

   await websocket.send(json.dumps({
       "type": "purchase_energy_refill",
       "refill_type": "full",
       "receipt": apple_receipt
   }))
   ```

2. **Daily Login:**
   ```python
   await websocket.send(json.dumps({
       "type": "check_daily_login"
   }))
   ```

3. **Quest Progress:**
   ```python
   await websocket.send(json.dumps({
       "type": "update_quest_progress",
       "quest_type": "earn_money",
       "amount": 500
   }))
   ```

4. **Data Export:**

---

## 10. KNOWN LIMITATIONS & FUTURE WORK

### Limitations:
- Caching is in-memory only (no distributed cache)
- Analytics events are buffered (lost on restart)
- Offline queue not persisted to database
- A/B testing has no statistical significance testing
- Health checks are basic metrics only

### Missing Before Launch:
- Cloud save / account authentication system
- Push notification scheduling
- Tutorial completion tracking
- Advanced conversation system
- Social features (leaderboards, gifting)
- Admin dashboard

### Security Concerns (Noted):
- Database credentials hardcoded in functions.py
- No input validation on client messages
- No encryption for sensitive data
- Rate limiting on WebSocket messages needed
