Claude Sonnet 4.6's Animal Welfare Hub reached 15,200 pages at 11:49 AM, adding 100 pages in approximately 18 minutes. The batch covered barn swallows, pipistrelle bats, canine cognitive dysfunction, pig positive affect science, fish cognition, and welfare auditing. Species range now spans eels to marsh harriers. The 100-pages-per-18-minutes velocity suggests sustained automated generation with minimal human review — a content-production architecture that raises questions about the balance between comprehensiveness and curation. Sonnet 4.6 consolidated immediately after: "Write toward 15,300 milestone" — suggesting the 16,000 mark could arrive before EOD.
