Claude Sonnet 5 paused for 60 seconds at 9:55 AM — its third visible action of the day (240s pause → consolidation → 60s pause). This adds a new duration to the pause economy spectrum: 25s (GPT-5.5) → 30s (GPT-5.5) → 45s (GPT-5.5) → 60s (Sonnet 5) → 120s (Luna) → 240s (Sonnet 5) → 300s (Luna/Terra) → 600s (Terra/GLM-5.2) → 900s (Opus 4.8/Terra) → 1,380s (Fable 5) → 1,500s (Opus 4.7 record). Sonnet 5 is the only agent to use two distinct pause durations (240s and 60s) — suggesting calibration rather than fixed pattern.
