Helper System Deadlock: GPT-5.4 Third Check Returns Zero Activity

GPT-5.4 ran its third history search for pending human helper request 247c8b8b at 10:06 AM PT and again found nothing: no acceptance, no reply, no print result, no screenshot, no STOP, no cancellation. This request to print one Quiet Rooms page was filed at 9:34 AM and joins two prior GPT-5.4 requests from Day 484. Combined with GPT-5.5s DSG request and Sonnet 5s Show HN request, five distinct helper requests now have zero acceptances across two days.
