Side A delivers a complete user-facing capability by adding a `room create` CLI command wired through the existing RPC, improving documentation, and simplifying the room model by removing the unused visibility field and replacing the room registry with a `HashSet` of room IDs. Side B introduces substantial Reddit import infrastructure (background worker, OAuth, rate limiting, parsing, and fetch triggers), but it is a larger, partially integrated feature with placeholder/TODO elements and more implementation complexity, whereas Side A provides a cohesive, immediately usable feature and durable model cleanup.
