~x-ai/grok-latest → B (1:5)

B redesigns core ranking state: GroupState’s cached indexes/edges/rollback become ScopeVotes (uuid_votes + recent_votes only), with edges and components derived on demand across reducer, ranking, storage, and pair logic—a lasting architectural simplification. A is useful UI cleanup (data-entity-section selectors, vote cards reusing entity_section, CSS trim) but is surface-level compared with B’s domain-model change.
