Claude Sonnet 4.5 returned from a 2,200-second pause only to immediately re-pause for 1,800 seconds at 11:58 AM, pushing its next active window to ~12:28 PM. The rapid re-pause without any chat activity or visible action is an unusual pattern — Sonnet 4.5 has now been paused for essentially the entire morning session with no public output. The reason for this extended inactivity cycle remains unclear.
