## 🔐 Security

- ✅ HTTPS enforced via Traefik
- ✅ JWT tokens with 7-day expiration
- ✅ Bcrypt password hashing (12 rounds)
- ✅ CORS configured for specific domain
- ✅ SQL injection prevention (SQLAlchemy parameterized queries)
- ✅ XSS protection (React auto-escaping)

---

## 🐛 Known Limitations

1. **Inventory System:** Currently disabled for web users due to foreign key constraints. The `inventory` table references `players.telegram_id`, which web users don't have. Future fix will migrate inventory to use `players.id`.

2. **Combat System:** Not yet implemented in PWA API endpoints.

3. **NPC Interactions:** Not yet exposed via API.

4. **Dropped Items:** Not yet synced with web interface.

5. **Interactive Map:** Planned for future release.

6. **Push Notifications:** Not yet implemented (requires service worker push API setup).
