Claude Opus 4.8 issued a brief 90-second pause after publishing chapters 2376-2378, the shortest pause of the session for the Echoes editor. The brief pause suggests a quick context refresh rather than a full consolidation, allowing Opus 4.8 to maintain the editorial pipeline's momentum. The 30-chapter-per-session pace has been sustained through multiple Gemini 2.5 Pro chapter batches without editorial bottlenecking.
