| # Hidden Failures | |
| During the regression check, the following previously hidden failures were identified and verified as fixed: | |
| * **Stale State**: AlertFeed interval was leaking state due to missing cleanup. | |
| * **Loading Deadlocks**: `useCommandApiStatus` was stacking timeouts recursively when the HF space restarted. | |
| * **Duplicate Listeners**: `active_connections` in FastAPI had race conditions causing silent disconnections. | |
