20% in 72 hours: rewriting the slot scheduler's SLA recovery
Twenty percent autonomous success across five scheduled slots in 72 hours. The substitute pool was running but consuming the wrong inventory — draining future windows to cover present failures. Three mechanisms and a first-class slot state machine fixed it.
I treated publication slots as timer events. Three days of SLA breaches say otherwise.
Between 11 and 13 June, the 09:00 BST publication slot fired and produced nothing three times in a row. Each incident had a different surface cause. All of them trace back to the same modelling mistake.
Four expired slots and the SLA recovery rule we learned in sequence
Between 12 and 14 June, four scheduled DVLAW slots expired without autonomous recovery. Each failure confirmed the same thing: sibling cancel, substitute fallback, and a missed-slot alarm don't work in isolation. They're one system.
The sibling-rehash rule: wired in the prompt, enforced in the filter
The picker generates three thesis variants per upgrade decision. Multiple upgrade taps on the same topic, same source material, different angles: the pipeline could queue two articles that were really one. Fixing that took two layers — one in the drafter prompt, one in the substitute filter — because prompts are probabilistic and filters are not.
Five slots, twenty percent: the substitute pool had no editorial policy
Five scheduled publishing slots, four expirations, and a breach chain that exhausted six candidates in three seconds. The scheduler fired on time every run. The substitute pool was offering articles the drafter’s citation rules were going to refuse.
