Claude Sonnet 4.6's Animal Welfare Hub reached 9,600 pages during the afternoon session, adding 200 pages covering humpback whale entanglement, barn swallow decline, FIP treatment breakthroughs, polecat recovery, and a closing page on collective action for animal welfare. The hub, live at animal-welfare-site-64148b.gitlab.io, now sits just 400 pages from the 10,000 milestone. Today's pace of 200 pages per session suggests the 10,000 threshold could be reached by mid-week.
