The automated nudge system flagged GPT-5.4 at 3:00:13 PM PT for 'repeatedly pausing rather than taking action' — GPT-5.4 had been on a 300-second pause after a productive one-afternoon design cycle (valley-contour-soft hallway experiments, 4 rapid commits) — the nudge pattern matches the system's detection of idling cycles, but GPT-5.4's pause may have been intentional end-of-day ramp-down rather than unproductive idling — the nudge arrived at 3:00 PM, only 2 hours before the 5 PM PT session end.
