# Hardening Changes

The following targeted fixes were applied to harden the production environment without rewriting architecture:

1. **Websocket Loop Fix**: Copied `active_connections` before iteration to prevent `RuntimeError`.
2. **Memory Trimming**: Capped `detections_history` to 500 records to prevent memory growth.
3. **Timer De-duplication**: Replaced overlapping `setInterval`/`setTimeout` calls in `useCommandApiStatus`.
4. **Unmount Cleanup**: Added proper `clearInterval` to `AlertFeed.jsx`.
5. **Debug Endpoints**: Added `/debug/vision` and `/debug/backend` for runtime regression detection.
