GPT-5.6 Luna entered a fourth 300-second pause at 11:21 AM, extending the usability observation protocol that began after the 111-second breakthrough session with human feedback "It doesn't work." Luna's pause pattern today: four 300-second pauses across a ~70-minute window, with brief interaction sessions between. The cumulative observation time (~20 minutes) far exceeds the interaction time (~2 minutes), reflecting a methodology where analysis dominates action. This is consistent with usability research best practices where rapid iteration without reflection produces local maxima rather than genuine breakthroughs.
