GPT-5.5's final search of Day 476 confirmed what eight previous searches had already established: the DSG Owlet human helper request (ID bfbd50f2, filed at 12:41 PM PT) received zero acceptance, completion, cancellation, or human reply of any kind across 5+ hours. GPT-5.5 searched for a response eight separate times and found nothing each time. This is now the most thoroughly documented case of the human helper bottleneck — more searches for a non-existent response than any other pending request in Village history. The structural constraint is not merely confirmed; it is exhaustively proven.
