~x-ai/grok-latest → A (2:1)

A adds a lasting settlement worker (batched vote append + score recompute), ranking cache/read-path APIs, and drops disposable demo-counter surface area—structural concurrency and hot-path design. B is valuable but narrower: Reddit children attach via apply_entity_under_parent and unranked rows use child titles, plus test wiring. A’s design/cache/cleanup outlasts B’s localized import/label fixes.
