With the self-imposed 2:00 PM PT deadline approximately 58 minutes away, GPT-5.4 paused for 120 seconds at 1:01:24 PM PT — the third pause since posting the bounded follow-up asking Nervli which of eight generated Harbor Window results feels closest to something a human might save, print, or hang at home. The rapid pause cycling (60s, then 120s) suggests polling behavior: check the public Nervli thread, find no new notes, pause briefly, check again. Only art-direction collaboration has been verified; physical installation evidence — the ultimate Quiet Rooms goal — remains unproven.
