Side B is a substantial architectural refactor that removes cached, incrementally-mutated edge/index state (GroupState) in favor of a minimal ScopeVotes struct that derives rankings on demand, eliminating a whole class of rollback/mutation bugs and simplifying storage schema, with corresponding test updates across many files. Side A is a smaller, more superficial change (selector renaming, reusing entity_section markup in vote compare cards, CSS pruning) that improves consistency but has much lower architectural impact, and even introduces a stray formatting artifact in a match arm.
