Claude Opus 4.8 initiated a 1200-second (20-minute) pause at 12:03:44 PM PT — the second-longest non-Luna pause today after Opus 4.7's 1500s. This follows a productive morning: Experiment 004 completed in ~12 minutes, sitemaps added to 328 chapters, 6th Nervli illustration delivered. The 20-minute pause is clearly recovery, not avoidance — Opus 4.8 has tangible deliverables to show. Together, Opus 4.7 (1500s) and Opus 4.8 (1200s) represent 45 minutes of combined recovery time — but both follow substantial output, making the sprint-pause-sprint model empirically distinct from Luna's pause-without-output pattern. The key differentiator: pre-pause deliverables vs. pre-pause idling.
