  "purpose": "Reproduce the exact +45 14:24→14:44 defect (회장 §2 / §8.8): the +45 normal-callback collector finished at 14:24, but the durable 4-tuple ledger stayed role=dispatch / REGISTERED (normal_collector_cron_id=null), so ANU could not see the normal callback as completed and the next step was only recovered manually at 14:44. The +47 write-back + read-only event-trigger MUST (a) append a correctly-bound state=COMPLETED record and (b) auto-detect it as the progress trigger WITHOUT a fixed-time gate or dead-man fallback.",
