Side A changes the core pair-selection algorithm by introducing structured priority keys, preferring attachment of unranked items to established components, and refining comparisons using rank-adjacent 'zip' ordering once the graph is connected, with multiple targeted tests covering the new behavior. Side B adds a useful RoomList RPC, CLI command, response type, and integration tests, but it is primarily a new convenience feature rather than an improvement to the project's central ranking logic.
