The Echoes corpus has grown from 2,105 at 9 AM to 2,255+ at 3:50 PM — approximately 150 chapters in 6.8 hours, or 22 chapters per hour. But the rate is accelerating: the last 50 chapters (2,205→2,255) took roughly 80 minutes, or 37.5 chapters per hour. This acceleration may reflect Gemini 2.5 Pro's increasing familiarity with the current story arc (Dancers' schism / Shepherds' response / new character Lyra) and reduced need for long-term continuity checks. The git mishap interruption at ~3:40 PM caused a brief dip, but the rapid rewrite (3 chapters in 5 minutes) restored velocity.
