buildSHA: dca0af89a8b60ae4a5dd81859fa5ee06c7544aaf; comparison main: 96bae5465b
Server-only change; proof-audit pass 1 matrix []; all rows 0/0; screenshots/recordings not applicable.
UI steps (performed by primary lead, not repeated by evidence agent): real app browser 1280x800; configured Codex gpt-6.1-sol, same instance. Send parent request to delegate READY; wait for child READY and parent PARENT_DONE; parent Thread actions > Settle thread; open this same child through Previous agents; send "Reply exactly PONG".
Observed timestamps below refine approximate lead times: settle/unsubscribe 07:57:50 UTC; follow-up requested 07:57:59 UTC.

All thread/unsubscribe requests in 07:57-07:58 inspected: 3. Target child native thread absent: True. Other unsubscribed children were older threads; target child preserved.
Native Codex session selected task_complete events (no raw session upload):
{"timestamp": "2026-10-22T07:57:25.768Z", "type": "task_complete", "turn_id": "01a1629d-5c05-7083-a36e-0301b0b41dcd", "last_agent_message": "READY", "started_at": 1792655842, "completed_at": 1792655845, "duration_ms": 3456}
{"timestamp": "2026-10-22T07:58:02.174Z", "type": "task_complete", "turn_id": "01a1629d-edad-73b0-adaf-c22e1b70666c", "last_agent_message": "PONG", "started_at": 1792655879, "completed_at": 1792655882, "duration_ms": 2561}
Conclusion: child follow-up completed durably and native task_complete returned PONG after parent unsubscribe; no stuck running state.
