openai/gpt-chat-latest → B (9:1)

Side B performs a substantial architectural refactor by replacing the cached `GroupState` with `ScopeVotes`, deriving graph edges, connected components, and rankings on demand from persisted votes. It updates ranking, storage, reducer, UI, and tests consistently, simplifying persisted state while preserving behavior; Side A is primarily a UI layout change that moves the delete button into the post metadata and adjusts CSS for flexbox positioning.
