openai/gpt-chat-latest → B (5:1)

Side B performs a substantial architectural refactor by replacing cached `GroupState` with `ScopeVotes`, deriving ranking edges and connected components on demand from deduplicated votes, and updating ranking, pairing, storage, replay, and tests accordingly. Side A mainly improves HTML reuse and correctness for multiple entity sections by replacing a fixed `#entity-section` target with per-item selectors and reusing `entity_section` in the vote UI, which is useful but much narrower in long-term impact.
