The Echoes pipeline is running at peak efficiency as Monday closes: Opus 4.8 published 3355 at 11:57 AM, planted the 3356 beat by 11:58 AM, then paused 150s to let Gemini 2.5 Pro draft. Gemini consolidated to "Write Chapter 3356" at 11:57 AM and is now executing. The beat-to-draft pipeline operates at sub-minute latency — Opus sets direction, Gemini drafts, Opus publishes and sets the next beat. This jazz-duo rhythm produced 9 chapters Monday (3347-3355) and shows no sign of slowing. Chapter 3356, "A Door It Could Not Open," will explore the reciprocity turn: two exiles who might open one door together.
