An initial root-checkout startup defaulted to ~/.t3; it was stopped before scenario testing and restarted with the explicit isolated home above.

Main attempts:
1. Native child sleeping; queue follow-up while active; click Stop.
   07:52:17.034 root turn/interrupt sent.
   07:52:17.056 child turn/interrupt sent.
   07:52:17.059 root turn/completed interrupted.
   07:52:17.082 child turn/completed interrupted.
   No child turn started after Stop. No late-subagent timeout warning.
2. Three real native children completed successfully (fourth hit native thread limit).
3. Completed native child's follow-up started a second turn while parent active.
   Parent and child Stop both completed at 07:58:39.
4. Native child created persistent active goal; parent Stop at 07:59:43.
   Both turns interrupted; no autonomous late child continuation appeared.
5. Independent thread native followup_task targeting stopped child's UUID returned agent not found.

PR native follow-up and simultaneous neighboring thread (all on provider-instance:codex shared app-server):
08:08:28.245 child first turn started.
08:08:32.247 child replied first_task_complete.
08:08:32.273 child first turn completed.
08:08:37.841 same child second turn started via native followup_task while parent active.
08:08:53.196 child timeout 90 sleep 60 command started.
08:09:08.992 neighboring root's timestamp/tick command started.
08:09:27.519 parent turn/interrupt sent from web Stop.
08:09:27.626 parent interrupt reply received.
08:09:27.627 child turn/interrupt sent; parent turn/completed interrupted.
08:09:27.657 child interrupt reply received.
08:09:27.659 child turn/completed interrupted.
08:09:32.892 neighboring thread command completed.
08:10:28.437 neighboring thread replied neighbor_complete.
08:10:28.951 neighboring thread turn completed.
The proxy emitted responseStreamDisconnected/reconnecting events on main and PR, and recovered. These were not ten-second late-subagent warnings.

Checks via task-owned Blacksmith:
vp test run apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts: 87 passed.
vp run check:changed ed44f251d89d4dae2f8dcf11c24fb3dec9dda4c7: passed format, lint, both knip passes, graphql, affected typechecks, 87 adapter tests.
The shallow worker needed an explicit fetch of PR history before check:changed.
Existing CI: 28 successful, zero failing/pending at checked head.

LIMIT: No actual native child turn began after a terminalized parent in these attempts.
The changed late-child branch was therefore NOT exercised live, and main's original reader freeze was NOT reproduced.
Ordinary native child completion, native follow-up while parent active, parent/child Stop, and another Codex thread were exercised successfully.
Native mobile, Electron shell, macOS/Windows, other providers and remote/relay/tunnel paths not exercised.
