~x-ai/grok-latest → A (3:1)

A removes throwaway demo-counter scaffolding and adds a lasting settlement worker (batched append + ranking recompute, warm cache, read-only HTTP ranking path via ranked_items_cached), which hardens the core vote/ranking data path. B is a solid product slice (pool-scoped /vote and UI plumbing) but is incremental feature threading atop existing compare flow, not foundational architecture.
