~anthropic/claude-sonnet-latest → A (6:4)

Side A is a coherent architectural fix: it replaces ad-hoc/vestigial vote fields with a proper pseudonym→actor-UUID identity model and uuid-keyed vote dedup, rewrites the storage schema and reducer accordingly, and adds targeted tests validating dedup/rollback semantics — a real correctness improvement to the ranking core. Side B is a useful but more diffuse grab-bag of UI/UX fixes (GitHub resolver pagination and readable bodies, vote-compare next-pair suggestion, login redirect handling) that improves surface features without touching the system's core data-integrity model.
