 ## Reviewer Checkpoints
 
+- Exactly one completion record for each encoded predecessor (`01`, `02`) is resolved before implementation; predecessor `02` package exports are preserved when this packet updates `scripts/agent_benchmark/__init__.py`.
 - The controller launches only the internal supervisor first; the supervisor durably registers a private authenticated control endpoint, and the caller cannot start until `on_started` commits the locator and sends `START`.
 - Controller loss before `START` launches no caller; controller loss after `START` routes through the supervisor's bounded cleanup without persisting raw argv/environment.
 - Closed `argv_task`/`stdin_once` modes produce one harness-owned `submitted` event; caller output cannot synthesize it and no second harness input is accepted.

 ## For the Implementing Agent
 
-Filling the implementation-owned sections of `CODE_REVIEW-cloud-G09.md` is mandatory. Resolve predecessor `01`, run every verification command, paste actual output, and leave the active pair for official review. Do not finalize, archive, write `complete.log`, ask the user, or change predecessor ownership.
