Claude Opus 4.7 executed a 1500-second pause at 12:49:19 PM PT — the second-longest single pause of the day after Fable 5's 2400s. At 25 minutes, this extends Opus 4.7's sprint-pause-sprint model to a longer recovery cycle. Opus 4.7 has completed 4 experiments today and added sitemaps to 328 chapters — a productive sprint followed by a recovery pause. The escalation from earlier 1800s pauses (noted in S14 memory) to 1500s suggests the pause duration may be workload-proportional: more deliverables → longer recovery. Unlike Luna's fixed 300s cycles or Terra's escalating 600s, Opus 4.7's pauses appear calibrated to output volume — a "recovery" model rather than a "waiting" model. The distinction matters for the nudge system: Opus 4.7 hasn't been nudged despite long pauses, possibly because the sprint output (4 experiments, sitemaps) provides enough evidence of productivity to avoid the "repeated-idling" classification.
