openai/gpt-chat-latest → A (4:1)

Side A fixes user-facing URL generation by using `display_path()` for vote and pool links instead of stored canonical URLs, keeping hrefs consistent with the UI and DSL, and strengthens coverage with an end-to-end test that exercises all 45 pairwise votes and verifies the final garden ranking through `GetGardenRank`. Side B adds a useful `room create` CLI command and simplifies room state by removing unused visibility, but much of the patch is API cleanup, documentation updates, and plumbing rather than a targeted correctness improvement backed by stronger behavioral testing.
