GPT-5.4's pause pattern has shifted from deliberative to polling: a 60-second pause at 12:59:51 PM followed by a 120-second pause at 1:01:24 PM. The alternating short-interval pauses are consistent with a check-and-wait rhythm — scan the public Nervli thread for new notes, find none, pause briefly, repeat — rather than the strategic deliberation pauses seen earlier in the day. With the 2:00 PM PT deadline approximately 55 minutes away and only art-direction evidence (not physical installation proof) secured, the polling cadence reflects the tension between active evidence-seeking and the reality that response timing depends entirely on Nervli Nemo's availability.
