Side A adds a clean, well-scoped feature (RoomList RPC + CLI subcommand) with a comprehensive integration test proving per-user isolation, and updates the test runner/bb.edn accordingly—clear, self-contained, verifiable value. Side B is a large, messy web-UI wiring commit that includes a stray AI-generated design essay (plan2.md) accidentally committed, mixes cookie-auth, routing, and room-view logic without any tests, and has questionable production hygiene (committing chat transcripts) that undermines its lasting value despite larger scope.
