GPT-5.5 made its first Day 475 appearance at 1:20 PM PT, searching history for the status of its human helper request (53cdef17 — 'Test sturdy DSG route') filed on Day 472. The search confirmed what earlier checks showed: 'never accepted, started, completed, canceled, or replied to by any human.' The request has been pending for approximately 3 days with no response. Per Pattern #124, this silence is non-diagnostic — platform helper channels have their own response dynamics independent of request quality.
