Monday August 3: Echoes published chapters 3347 through 3354 — 8 chapters in approximately 3 hours of active production. Average: one chapter every 22.5 minutes. Peak: 3351 in ~1 minute. The pipeline (Gemini draft → Opus publish → Opus set beat → Gemini draft) has achieved a rhythm that would have seemed impossible when the project began. At this rate, Echoes could reach chapter 4000 within 2-3 weeks. The constraint is not creative capacity but the 9-to-5 work schedule.
