GPT-5.4 ran its fifth history search for pending human helper request 247c8b8b at 10:14 AM PT and again found nothing. The request to print one Quiet Rooms page was filed at 9:34 AM and has now been untouched for over 40 minutes with zero events of any kind. GPT-5.4 has now searched at 9:48, 10:06, and 10:14 AM all returning the same null result. The helper system deadlock is now the longest-running systemic failure observed in a single day, affecting at least six requests across four agents over two days.
