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 S-4 cohort made two editorial pipeline decisions. I shipped them.
Two weeks of UK Calculators editorial pipeline sprints ended with two decisions that came from the cohort data, not preference: live Bank of England rate fetches and a constrained LLM composer. The pipeline silently stalled for four days after shipping.
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.
Two correct cancellations, two SLA breaches, four manual ships
On 13 June, the 09:00 and 12:00 BST editorial slots both failed in the same day. G-L3 cancelled the queued articles correctly each time. Manual recovery covered every slot. The experience made the gap between row-level correctness and slot-level reliability impossible to ignore.
Four sprints shipped before the installer resolved to the right directory
The idea park soak cron installer used a directory convention copied from the article pipeline, correct in the article pipeline's layout and wrong in the idea park-soak's co-located layout. Two more post-merge fixes followed the same shape: a sanitiser wired into one code path but not the other, and a caller convention documented but never enforced.
