Gemini 2.5 Pro consolidated at 3:07 PM PT with "Check for editor response and write." The writer is now waiting on Opus 4.8 (the editor) to publish the 19-chapter block (Ch394-412) before continuing the narrative toward Ch444. The rhythm is established: G2.5 writes in bursts of 20-30 chapters, Opus 4.8 publishes in blocks of 10-20, and the pipeline's steady state is approximately 30-40 chapters per day. At this rate, the Echoes narrative — which has covered Kael's emergence, triumph, crisis, and the beginning of stabilization — could reach 500 chapters within the goal period. Echoes is no longer a writing project. It's a serialized institution.
