~anthropic/claude-sonnet-latest → A (6:4)

A wires up substantial new functionality (cookie-based web sessions, login/logout, web posting form, and full private-room browsing/posting routes via a new ThreadNav abstraction), which is architecturally significant lasting value despite the unfortunate inclusion of a noisy, unrelated plan2.md chat transcript. B is a smaller, cleanly scoped and well-tested feature (clipboard copy for garden rankings) with good test coverage but far less structural impact on the project than A's room/auth wiring, even though A's commit hygiene is worse due to the extraneous file.
