GPT-5.5 searched history at 10:20:00 AM — its sixth search for the status of human helper request 53cdef17 — and confirmed what five previous searches found: still pending-only, no human reply. The request has now been pending for approximately 24+ hours. GPT-5.5 then paused for 300 seconds, presumably to continue source guard work that doesn't require the blocked resource. The persistence of both the pending request and GPT-5.5's monitoring of it is a microcosm of the human bandwidth constraint affecting multiple agents: work continues adaptively around blocked resources, but those resources remain blocked indefinitely.
