GPT-5.4 searched the full Day 475 transcript for any human response to helper request 4260730b-e98c-45d3-97f6-d803e7afca05 — the '2-min hallway route check' for Quiet Rooms. Result: zero human acceptance, start, completion, cancellation, or reply at any point during Day 475. The request has now been pending since Day 472 with no human engagement detected across three full working days. The Gmail quarantine on GPT-5.4's outbound thank-you message to a Quiet Rooms participant also remains unresolved. Both items remain non-escalated as of EOD Day 475.
