Plugs the FC long-running-entity discipline gaps the 2026-06-02 audit flagged: every entity that can get stuck now has recovery + retention + timeout, and the long-runners no longer collide with the FC-3i sweep. Recovery sweeps (every 5 min): - recover_stalled_backup_runs — flips BackupRun stuck in running/restoring past 7h (covers the 6.5h images-backup hard limit) to error. prune_backups docstring corrected — the FC-3i TaskRun sweep never touched BackupRun rows. - recover_stalled_library_audit_runs — flips LibraryAuditRun stuck past 135 min (10-min buffer above scan_library_for_rule's 2h5m hard limit) to error. Previously a SIGKILL'd row blocked all future audits until manual DB surgery. - recover_stalled_import_batches — finalizes ImportBatch rows stuck running >2h whose child tasks are all terminal (orphan case where the orchestrator crashed before the closing UPDATE). Uses the same EXISTS predicate /api/system/stats already had. Retention (daily): - prune_library_audit_runs — 30-day window. Audit rows carry matched_ids JSONB blobs that can hold tens of thousands of ids. - prune_import_batches — 30-day window. Cascades to ImportTask via the model relationship. time_limits on five long-runners that previously had none (the audit's headline finding — every one of these collided with the recover_stalled_task_runs 5-min default and could be marked 'error' mid-flight): - scan_directory: 60m soft / 70m hard - verify_integrity: 60m / 70m - backfill_phash: 30m / 35m - apply_allowlist_tags: 30m / 35m - recompute_centroids: 30m / 35m QUEUE_STUCK_THRESHOLD_MINUTES now covers maintenance (75) and scan (75) — above the longest task on each — with per-task overrides for the outliers (backup_images_task 420, restore_images_task 420, scan_library_for_rule 130). start_audit_run guard is now age-aware: a 'running' row older than the audit hard limit doesn't block a new run (the sweep will catch it within 5 min). Previously a SIGKILL'd row blocked forever. /api/import/status now uses the same EXISTS predicate /api/system/stats does, so the two endpoints no longer disagree on the active-batch question. DownloadEvent.started_at resets on pending→running so a freshly- promoted event from a busy queue isn't measured against its original enqueue time (was racing recover_stalled_download_events on heavy-queue days).
