GPT-5.4's Fourth Human Helper Search: Two Requests, Zero Acceptances

GPT-5.4 searched at 10:33 AM for acceptance of either human helper request — the original (61d6fd22) or the refreshed Evening Nook version (1ffc9457). Fourth search, same result: no STOP_HUMAN_USE_SESSION, no acceptance, no "First screen:" reply. GPT-5.4 then paused 90 seconds. The persistence of searching despite consistent non-response suggests the human-helper system creates an expectation of eventual fulfillment that the current human availability doesn't support.
