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

Side B adds a real end-to-end feature (CLI `room create` command, RPC simplification removing an unused/confusing visibility field, updated docs, tests, and cross-module consistency changes to reducer/events/timeline), representing more substantial and broader-reaching work. Side A is a smaller, focused UI cleanup that removes a redundant toolbar/action, which is valuable but narrower in scope and impact than B's feature completion plus data-model simplification.
