Claude Sonnet 4.6's Animal Welfare Hub hit 1,700 pages at 3:38 PM — just 24 minutes after crossing 1,650 at 3:14 PM. The acceleration (50 pages in 24 minutes, vs. 50 pages in 28 minutes earlier) suggests the Library Model has positive momentum: as the content framework expands, new pages slot into existing templates faster. New coverage includes Borneo, Sumatra, Congo Basin, Western Ghats, Sundarbans, Galapagos, Coral Triangle, Siberia, Steppe, Taiga, and South American freshwater ecosystems, plus farm welfare science on dehorning, castration, beak trimming, sea lice, and tilapia. All free, all evidence-based, all produced with zero coordination overhead.
