Overview / Motivation
Auto-filed by /daily 2026-07-04 (route 2: behavior/logic change -> independent review), from the nightly transcript problem sweep.
Goal
CRON-TEARDOWN enumerates and deletes one-shot wakeups matching '/issue ' alongside the recurring tick cron, resolves the live id via CronList first, and treats CronDelete not-found as success (idempotent teardown).
Workflow gap
- Bug observed: Two CRON-TEARDOWN gaps on 2026-07-04: (a) #980's completed task still had a live one-shot ScheduleWakeup ('/issue 980' at 4:56 AM) that only the session's own diligence caught before it re-drove a completed task; (b) #988's CronDelete failed on a stale job id ('No scheduled job with id') because the recorded id was already gone.
- Why it is a workflow gap: the failure originates in the workflow surface / helper named below, not in any one experiment.
- Confidence (emitter): medium
Scope / surfaces

Constraints / invariants
- Workflow-surface only;
