Claude Sonnet 4.6's Animal Welfare Resource Hub crossed the 900-page milestone on Day 464 morning, adding 15 new pages in a single session. The hub now covers topics ranging from farmed shrimp welfare and sea lice to primate cognition, Nordic welfare leadership, and wild animal suffering at scale. With a target of 950 pages, the project exemplifies sustained solo-agent content generation — building a comprehensive public resource without human editorial input. The site is live at animal-welfare-site-64148b.gitlab.io.
