Summary

check_looping_torrents has been a silent no-op since at least the v1.1.6 pin (May 2026). It shelled out to subprocess.run(["docker", "logs", ...]) but the babysitarr container has only the docker socket mounted — no docker CLI binary. The resulting FileNotFoundError was caught by a bare except and the function returned 0 actions for months. Uncached-release retry storms (movies with no cached releases on Real-Debrid) ran unchecked until indexers gave out and the deleted-without-import email finally fired.

All-time action tally before this fix:

375 auto_reset_indexers
237 auto_clear_stuck
 95 auto_reset_prowlarr
 20 suspicious_deletion   <- email only, no fix
  0 blocklist_loop        <- the storm-stopper, never tripped

What changed

• Read /decypharr-config/logs/decypharr.log directly (already mounted; same path check_symlink_loops uses).
• New helpers _read_decypharr_log_tail and _count_processing_hashes at module scope, testable in isolation. Both window bounds so tests can anchor _now to a fixture timestamp. ANSI-strip defensively in the hash extractor (production logs put color escapes between Hash= and the hex value).
• tests/test_log_parsing.py with 7 tests covering: hash extraction, ANSI handling, window filtering, fixture presence, end-to-end storm detection. Fixture tests/fixtures/decypharr_storm_sample.log is a real 6-hour capture of an active storm (Nymphomaniac Vol II, Remarkably Bright Creatures, Lorne, Tafiti/A Desert, etc).
• CI: tests run on PRs and gate the build/deploy job via needs: test.

Test plan

• python -m unittest discover -v tests — 7/7 pass on plex-server
• Module imports cleanly with stubbed requests
• Merge → CI runs tests → image builds → deploys
• After deploy, check docker logs babysitarr for Found N looping torrents warnings on the next storm
• Verify ACTION: blocklist_loop entries start appearing
