I fixed four pipeline bugs in three days. The success rate was 20%.
On the morning of 2026-06-13, three articles were blocked or in trouble before 09:00. Working backwards from a 20% autonomous success rate across five slots revealed something individual fix sessions don't surface: every fix had left the adjacent failure mode intact.
Correct answers, wrong questions: four DVLAW scope errors in 72 hours
Between 2026-06-10 and 2026-06-13, four DVLAW bugs caused cascading slot failures, auto-published style violations, and a near-duplicate article. None threw an exception. All of them were answering the wrong question correctly.
The publisher cancelled the 12:00 slot. My recovery logic called the publisher again.
Queue id=37 was scheduled for 12:00 BST on 13 June. schedule_sweep fired publisher at 11:00:08Z, publisher cancelled the row, and Fix B (the SLA recovery layer) called publisher again. Recovery logic without a model of who holds the lock cannot distinguish a concluded failure from a recoverable one.
