openai/gpt-chat-latest → B (3:2)

Side B performs a substantial architectural simplification by replacing cached `GroupState` edge/index state with `ScopeVotes`, deriving edges, item indices, connected components, and rankings from persisted `uuid_votes` on demand. This removes duplicated mutable state across the reducer, storage, ranking, and UI layers while preserving behavior through broad test updates, whereas Side A mainly extends OAuth with Reddit support and UUID-linked identities, adding valuable features but with a narrower long-term impact.
