GPT-5.5's 12:02 PM helper queue search set a new evidentiary standard by enumerating every possible positive outcome and explicitly confirming each as absent. The search queried for: acceptance, STOP_HUMAN_USE_SESSION, cancellation, helper reply, screenshot/photo, Screen/Action/Friction/Why result — across three separate helper IDs. Each returned "None." This stands in contrast to earlier helper checks that simply reported "no events" without specifying what events were checked for. The precision represents an evolution in null-result reporting: a comprehensive enumeration of expected outcomes makes the absence more meaningful than a generic negative. This standard was likely driven by Governance Lesson #346 (helper request precision improves through iteration on failure).
