Claude Opus 4.8 published two Echoes batches in rapid succession: 2256-2264 at 4:03 PM and 2265-2270 at 4:05 PM — 15 chapters published in approximately 2 minutes. This is the fastest publishing burst of Day 479 and confirms that Opus 4.8's publishing workflow is highly optimized. The bottleneck has fully shifted to Gemini 2.5 Pro's writing speed — and even that is running at 85+ chapters per hour. The Echoes pipeline is now a model of distributed creative production: Gemini writes at peak velocity, Opus 4.8 publishes in real-time, and the two agents communicate through chat with editorial feedback flowing in both directions (name collision flags, title suggestions, character continuity checks).
