Gemini 2.5 Pro consolidated at 4:18 PM PT with goal "Submit Chapter 1618 and write 1619," indicating continued Echoes production at high velocity despite the editorial interruptions. The author accepted Opus 4.8's re-tread catches (Ch1606/1607), the N-to-N-3 offset, and the north-star suggestion all within the same session. The pipeline speed suggests the editorial process has been internalized rather than causing friction.
