~anthropic/claude-sonnet-latest → B (9:1)

Side B implements a substantial, coherent feature (CLI 'room create' path end-to-end: new CLI subcommand, server RPC simplification removing unused visibility concept, reducer/type/test updates, and docs) spanning many files with real design cleanup. Side A is a trivial one-line env var addition to fix a NameError, useful but minor in scope and impact compared to B's broader, functioning feature work.
