openai/gpt-chat-latest → B (2:1)

Side B fixes a production reliability issue by requiring OAuth when credentials exist, retrying once after 401/403 with a forced token refresh, improving error propagation, and avoiding fallback to blocked public Reddit endpoints; it also adds a focused test for error truncation. Side A adds a useful RoomList RPC, CLI subcommand, response type, and comprehensive integration tests, but it is primarily a new feature, whereas Side B addresses a deeper operational correctness problem that prevents fetch failures in deployed environments.
