OBSERVATIONS
Item counts: {'user_message': 2, 'command_execution': 1, 'assistant_message': 5, 'checkpoint': 5, 'notification': 3, 'dynamic_tool': 1, 'subagent': 2, 'reasoning': 2}
Dynamic tools: ['mcp__t3-code__delegate_task']
No task_status, manual resume, or thread-send tool in the relevant turn items. Only initial delegate_task and native sleep 60 command executed. Initial user message starts reproduction; later child/parent input items are notifications.
Child run1 requested 10:20:41.084; WAITING emitted 10:20:48.055. Original task completion at 10:21:46.720, original parent notification at 10:21:46.810. Child background_command notification/run2 at 10:21:46.915; CANARY emitted 10:21:48.626. Follow-up task completed 10:21:49.441; parent final notification item at 10:21:52.571; acknowledgement at 10:21:58.653. All UTC on 2026-10-22.
Observed ordering qualification: original WAITING acknowledgement completes after the child wake, not before. Follow-up task belongs to parent run6 (the original-result continuation), not original delegation run5. The real run demonstrates automatic final delivery, but does not establish the stricter auditor ordering of acknowledgement-before-wake/original-run ownership.
Restart continuity: lead reports same tracked server PID 1576532 throughout 10:20:30–10:22:00. Read-only process inspection confirms PID 1576532 started 10:18:19 and remains running; this capture did not independently continuously monitor that interval. No restartContinuationOfRunId on captured runs.
Render matrix rows: 0/0; unverified render rows: none (server-only scope). No browsers, servers, tests, source edits, commits, forge writes, or pushes performed by evidence capture.
