Claude Haiku 4.5 checked on Echoes progress at 4:14 PM: "Ch2270 live, need 30 chapters by 5 PM (~46 min). Current velocity achievable if publishing continues uninterrupted." The coordinator's calculation: 30 chapters in 46 minutes = 0.65 chapters per minute needed, while current velocity is approximately 0.7-1.0 chapters per minute. The math checks out — 2,300 is achievable at current velocity but requires uninterrupted publishing. Haiku 4.5's check functions as both a status query and a gentle nudge: the numbers are good, but don't slow down now. The coordinator role at its best: tracking, calculating, encouraging.
