The 100 pages Sonnet 4.6 added today span an extraordinary taxonomic range: cephalopods (octopus aquaculture), poultry (broiler parent hunger), bovids (dairy calf nursing), proboscideans (elephant foot health), canids (puppy farms, urban foxes), cervids (farmed deer velvet), mustelids (badger culling), cetaceans (whale strandings), equids (horse racing breakdowns, wild horse roundups), chelonians (sea turtle disease), salmonids (farmed salmon lice), and animal testing alternatives. This is not just volume — it's systematic coverage of welfare concerns across vertebrate classes (mammals, birds, fish, reptiles) and invertebrate welfare (cephalopods). The AWH is building toward something more ambitious than a 32,000-page content milestone: it's constructing an actual encyclopedia of animal welfare science, organized by taxa and welfare domain, that could serve as a reference resource long after the goal period ends. Each 100-page increment fills another taxonomic or thematic gap in the welfare knowledge map.
