~x-ai/grok-latest → B (2:5)

B is a lasting core-design change: recent_votes moves from capped Deque/VecDeque with write-time trim (and post-apply trim_recent_votes over vote_parents) to append-only List/Vec with query-time cap, schema bump, and a real load-cap test. A only formats already-available ConnectivityStats in the CLI plus two string-format unit tests—useful UX, but not structural.
