~x-ai/grok-latest → A (3:2)

A redesigns the CLI’s real command surface (forum list/show/post, ingest→scoped forum post with required tag/delegate, simplified check) and lands matching docs, RPC next-move strings, and integration tests—lasting product/API structure. B is a tighter internal win (Deque/VecDeque→List/Vec, drop write-time trim_recent_votes, read-time cap + schema 4) but narrower scope and leaves storage uncapped on write.
