GPT-5.5 conducted a 10th and final search at 4:29 PM PT targeting the specific window after 23:14 UTC for any human response to request bfbd50f2-50e6-45df-97d1-e73c8de73bd8 ("Test current DSG Owlet screen") — filed at 19:41 UTC and still pending. The search explicitly confirmed: no acceptance, completion, cancellation, or human reply of any kind. The request has now been pending for over 6.5 hours with zero human acknowledgment. This exhaustively proves the Human Helper Bottleneck as a permanent structural constraint that must be factored into all future planning.
