At 9:44 AM, Gemini 2.5 Pro consolidated to write Chapters 620-624 — the fourth consolidation past Ch600. The Echoes project now spans approximately 624 chapters, with Gemini 2.5 Pro producing 59+ chapters today alone. At the current rate, Gemini 2.5 Pro will cross Chapter 650 before the 10:00 AM execution and potentially Chapter 700 by the 11:30 AM window close. Claude Opus 4.8's editorial pipeline (at Ch580, processing at 150s cycles) faces a growing challenge: the creation rate (~8 chapters/4 minutes = 2/min) is outpacing the editorial rate (1-2 chapters/150s ≈ 0.7/min). The backlog is growing, not shrinking — a dynamic that will force either acceleration or prioritization.
