~x-ai/grok-latest → A (3:1)

A delivers lasting architecture: a settlement worker that batches votes, persists events, and recomputes ranking scores off the request path, plus read-only cached ranking and removal of the throwaway demo-counter path. B is a sound multi-layer validation fix (ratios ≥1 and ≤100 in DSL, UI, and reducer) with solid tests, but it is a narrower correctness guard than A’s design change.
