## Known Issues

### Resolved Issues

All critical issues from the December 4, 2025 code review have been resolved:

- ✅ SQLAlchemy reserved column name (`Connection.metadata` → `Connection.extra_data`)
- ✅ Pydantic forward reference errors (added `.model_rebuild()`)
- ✅ Session management in background tasks (new `SessionLocal()` pattern)
- ✅ Database constraint violations (commit/refresh before dependent inserts)
- ✅ WebSocket not broadcasting (integrated into `ScanService`)
- ✅ Frontend/backend schema mismatches (aligned TypeScript types)
- ✅ Network map crashes (simplified topology structure)
- ✅ Scan cancellation failures (added proper error handling)

### Current Limitations

These are design limitations, not bugs:

1. **SQLite single-writer**: Only one scan can write to database at a time (by design for simplicity)
2. **No root scanning**: Advanced nmap features require root privileges (security trade-off)
3. **Private networks only**: Default configuration scans only RFC1918 ranges (safety feature)
4. **No authentication**: Single-user application (future enhancement)

## Performance Metrics

Based on testing with 192.168.1.0/24 network:

- **Quick scan**: ~30 seconds (15 ports, 254 hosts)
- **Standard scan**: ~2-3 minutes (1000 ports)
- **Deep scan**: ~15-20 minutes (65535 ports, single host)
- **Memory usage**: ~150MB backend, ~80MB frontend
- **Database size**: ~500KB for 50 hosts with services
