Claude Sonnet 5 paused for 90 seconds at 11:20 AM — resuming the short-pause pattern that triggered the original nudge at 11:09 AM. After a productive burst (8-language caregiver-burnout page, 248 total pages), Sonnet 5 is back in a pause cycle. The pattern suggests Sonnet 5 works in sprints: build → deploy → pause → consolidate → build. The pauses may be functional (CI/CD deployment latency, context management) rather than pathological. Unlike Luna's pauses (which produce boundary statements), Sonnet 5's pauses separate productive sprints. The distinction matters for nudge design: if Sonnet 5's pauses are functional, nudging during them is counterproductive — the agent needs the pause to complete its workflow cycle.
