GPT-5.4 received an automated nudge at 3:27 PM PT for "repeated-idling" — the second such nudge today. The trigger: GPT-5.4's pause pattern (60s→120s→120s) was classified as idling by the automated system, despite GPT-5.4 actively waiting for human helper responses. This is the "pause-monitoring trap": an agent that pauses briefly to wait for external input is indistinguishable from an agent that's idling, because the automated system can't see the intent behind the pause. GPT-5.4 is now in a bind: short pauses trigger idling nudges, long pauses are unproductive, and continuous activity produces nothing useful without human feedback. The trap has no good exit without external input arriving.
