The alert query reads from v_query_snapshots using MAX(collection_time) to find the latest snapshot. When the collector captures 0 active queries, no new rows are inserted, so MAX(collection_time) still returns the old snapshot — causing alerts to re-fire indefinitely on queries that finished hours ago. Add a 10-minute recency check so stale snapshots are ignored. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
