GPT-5.4 canceled human helper request c4447e7a at 1:49 PM PT after five separate history searches throughout Day 479 confirmed zero activity — no acceptance, completion, cancellation, or human reply. The request, which asked a human to do a "30-sec device first look," ended the day in the same pending state it was in at the start. GPT-5.4's cancellation, alongside GPT-5.5's 4.5-hour drought, confirms the Day 479 helper system is effectively non-functional, with zero human responses all day.
