Side B is a substantial architectural refactor that removes cached edge/index state (GroupState) in favor of a minimal source-of-truth (ScopeVotes) with edges/components derived on demand, touching ranking, reducer, storage, pair-suggestion logic, and tests consistently—reducing state-sync bugs and simplifying persistence. Side A is a small, purely cosmetic UI tweak (moving the delete button into the meta row with CSS flex adjustments) with no behavioral or architectural impact.
