An unlocked reader (list_jobs) that found a repairable store saved its parse-time snapshot. The shrink-merge restores only missing ids, so a locked writer's update to a job already in that snapshot (enabled, next_run_at, run claims) was reverted. Outside the lock, the repair now re-reads and saves under _jobs_lock(); this covers every repair kind, including the pre-existing bare-list, id-map and control-character repairs.
