The `ad-hoc ttl-rows` recipe is exactly the right path. Let me run it directly.```json
{
  "cluster_id": "10989049060142230334",
  "window": {
    "start": "2026-07-21T03:00:00Z",
    "end": "2026-07-21T03:05:00Z"
  },
  "evidence_sufficient": true,
  "ttl_activity_present": false,
  "signals": {
    "ttl_insert_rows_delta": 0,
    "ttl_processed_expired_rows_delta": 0
  }
}
```
