Suggested reviewers: Merge Risk: 🟡 Moderate · up to Restart notices can be queued to an unsubscribed Codex task while the task still awaiting events remains asleep. The wake-state ownership model should be corrected before merge; the bookkeeping-write error path should also remain best-effort. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 5894-5899: Update the success branch of remember_codex_wake so the
mv -f operation is best-effort and cannot propagate a failure under set -e;
follow the existing guarded move pattern by cleaning up the temporary file if
the move fails, while preserving the current successful write flow.
In `@modules/src/webhook-cli.sh`:
- Line 52: Update the wake-file handling around the “mv -f” operation to persist
subscription ownership per session, and when selecting a restart recipient
choose a UUID that still owns an active topic rather than a partially
unsubscribed session. Add a regression test covering task B unsubscribing while
task A remains subscribed, verifying the wake prompt targets task A.

both findings addressed: mv -f guard fixed in 6c867c9; the wake-thread-ownership finding was withdrawn by CodeRabbit after clarification that subscriptions are owned per-session/filter, not per-topic (see thread on modules/src/webhook-cli.sh).

Summary
Why
Claude restart notices are injected as a resume prompt, but Codex was explicitly excluded. Codex Remote Control also has no positional prompt, while its local-webhook delivery peer dies with the user service even though the subscription filter survives. The existing
codex queue --thread ... --message ...delivery path gives us a safe wake-up mechanism when the task has subscribed.Tests
