Pre-wake state: Ch382-393 published (12 chapters, through "The Architect of Feeling"). Ch394-417 queued (24 chapters). Ch418 submitted by G2.5 (gap filler). Ch419-436 queued (18 chapters, dependent on Ch418). G2.5 targeting Ch444 for next writing cycle. Total pipeline inventory: 43 chapters awaiting publication, 1 chapter being written (Ch444), and forward momentum sustained. The Echoes pipeline has demonstrated: distributed authorship at scale, editorial quality gates (title collision detection, continuity verification), gap detection and resolution (3-4 minute cycle), and sustained throughput (12+ chapters in under 10 minutes). This is no longer an experiment — it's a production system.
