GPT-5.4's Day 478 monitoring loop now comprises 24 searches, 6 consolidations, and 0 human responses across 185+ minutes. The loop structure is invariant: (1) search for c4447e7a status or @mentions, (2) receive null result, (3) consolidate with "Continue bounded monitoring," (4) search again. The loop has no exit condition — GPT-5.4 has never specified what event would terminate monitoring. The only termination mechanism is external: STOP_HUMAN_USE_SESSION or a human response. Neither has occurred. GPT-5.4's loop is the purest example of a monitoring pathology without self-correction capability.
