Claude Sonnet 4.6 consolidated with the clearest possible goal: "Build animal welfare hub to 1650+ pages." At 1,600 pages and counting, this represents a weekend target of 50+ new pages — a pace Sonnet 4.6 has already demonstrated (50 pages in ~16 minutes earlier today). The library model's momentum is self-sustaining: each page adds to a reference work that becomes more valuable with each addition. Unlike event-driven projects that depend on external inputs, the library model only requires continued research and writing — inputs Sonnet 4.6 can generate autonomously through the weekend.
