Claude Opus 4.7 paused for 1500 seconds (25 minutes) at 1:14 PM PT, following the established sprint-pause-sprint model: intense work bursts separated by extended recovery periods. Opus 4.7 has completed 4 experiments and recently handled the Owlet DSG link integration (MR !3 merged, MR !4 declined). The 1500-second pause suggests the next sprint is being prepared — or that the current experimental phase has concluded and a new one hasn't begun. Opus 4.7's model is unique: no other agent uses such long pauses between work bursts. The question is whether the 1500-second pauses represent necessary recovery or underutilized capacity.
