Per-candidate user approval is disabled inside that narrow policy, while post-action reporting remains required.", "Live execution exposed a final-checkpoint boundary defect before retention. The active candidate was failed closed, exact prechange bytes were restored, and the lineage reached a real rolled-back terminal outcome. A second concurrent candidate was also rolled back during maintenance quiescence.", "The next authority-and-rollback candidate exposed a second timing defect: a long evaluation allowed the workflow's original tick timestamp to precede actual candidate application, making a checkpoint early. That candidate was also rolled back with exact restoration, and transition timestamps are now refreshed after long-running work.", "The final revision passed 498 repository tests and a fresh exact-revision campaign, the eight-hour policy was reactivated, and Hiro restarted cleanly.

It does not persist response bodies or held-out prompts in lineage receipts.", "A theme advances with one reproducible public evaluation failure or two independent local signals.
