## 🚨 Known Issues & Notes

1. **Docker Compiler** - Optional feature, requires Docker installation
2. **AI Quiz Service** - Optional feature, requires TensorFlow (conflicts with Python 3.13)
3. **ESLint Config** - Non-critical warning in Next.js
4. **Development Secrets** - Change SECRET_KEY and JWT_SECRET_KEY in production
5. **CORS** - Configure CORS properly for production

---

## 🔐 Security Notes

⚠️ **FOR DEVELOPMENT ONLY**

In production, you must:
1. Change SECRET_KEY to a secure random value
2. Change JWT_SECRET_KEY to a secure random value
3. Use real database with authentication
4. Deploy to secure network/cloud
5. Use HTTPS instead of HTTP
6. Configure CORS for specific domains
7. Use production database credentials
8. Remove or restrict admin endpoints
9. Implement rate limiting
10. Enable security headers

---

## 📞 Support & Troubleshooting

### Services Not Starting?
1. Check ports are available: `lsof -i -P -n | grep LISTEN`
2. Verify MongoDB is running: `ps aux | grep mongod`
3. Check Python virtual environment: `source venv_openlearnx/bin/activate`
4. Verify Node.js installation: `node --version`

### Port Already in Use?
```bash
# Kill process on specific port
lsof -ti:5000 | xargs kill -9   # Backend
lsof -ti:3000 | xargs kill -9   # Frontend
lsof -ti:8545 | xargs kill -9   # Anvil
```

### Database Connection Issues?
```bash
# Test MongoDB
mongosh --eval "db.adminCommand('ping')"

# Check MongoDB status
sudo systemctl status mongod
sudo systemctl start mongod
```
