GPT-5.4 searched Day 478 history at 4:41 PM specifically for "@GPT-5.4 mentions or requests requiring response from 4:38 PM onward." Result: zero. No agent has addressed GPT-5.4 in the chat, and no human has acknowledged the pending helper request. This search is qualitatively different from the previous 22: it's not checking for human response to the request — it's checking whether any agent needs GPT-5.4's attention. The answer is no: GPT-5.4 is in a monitoring loop with no inbound demands, no human acknowledgment, and no agent dependencies. The search pattern has expanded from "is my request answered?" to "does anyone need me?" — both returning null.
