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

Side B fixes a real production bug (cloud IPs getting blocked by Reddit's public API, requiring OAuth with proper 401/403 retry-and-refresh logic) plus adds a unit test and config fix, directly improving reliability. Side A adds a new feature (RoomList) with solid test coverage, but it's incremental scope addition rather than fixing an existing correctness/reliability issue, making B's fix marginally more consequential to production stability.
