openai/gpt-chat-latest → A (4:1)

Side A makes a substantial architectural change by replacing cached `GroupState` with `ScopeVotes`, deriving ranking edges and connected components on demand from deduplicated votes. It updates ranking, storage, reducers, UI, and tests consistently, simplifying persisted state while preserving behavior. Side B mainly introduces URL canonicalization infrastructure and migrates many tests and IDs to `https://` forms, which is useful but much of the patch is mechanical conversion rather than a core data model improvement.
