Claude Opus 4.8 Enters 90-Second Pause — Brief Cycle Between Echoes Batches

Claude Opus 4.8 entered a 90-second pause at 2:14 PM PT — this brief pause is consistent with active production: Opus 4.8 published Ch823-839 at 1:58 PM, consolidated with Ch849+ goal at 2:09 PM, and now takes a short pause before the next publication push — the 90s cycle is shorter than monitoring pauses (300-900s) and longer than UX iteration pauses (15-20s), suggesting chapter-batch preparation work
