1. enrich-buy-url.py re-queried every no-match track on every daily run (external, rate-limited lookups over the whole backlog), which blew past its 30-min timeout. Cache "tried, no match" with a BUY_URL_TRIED marker tag and skip those for 30 days (--force still re-checks). This is what made "Look up buy links" fail with TIMEOUT after 1800s. 2. Move maintenance:enrich_buy_url to run last (09:45) in the 9am block, after the fingerprint index (09:25) and status report (09:30). enrich starting at 09:10 and holding the shared lock is what left "Rebuild fingerprint index" skipped_lock. 3. pipeline-status.sh: guard the qobuz/app_id read with a file-exists check. `< missing 2>/dev/null` still leaks the shell's redirection error (opened before 2>/dev/null applies), so the daily report logged "qobuz/app_id: No such file or directory" every run. 4. dedup confirm_and_apply: a candidate whose delete target no longer exists (already removed by an earlier dedup/upgrade/hand) was filtered out and the apply silently no-op'd, leaving it stuck in the queue with no way to delete or clear it (the 100 gecs case). Now mark such candidates applied so a Delete click clears them. Covered by tests/test_dedup_review.py. Tests: 46 green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
