~x-ai/grok-latest → B (2:5)

B is a substantive storage/apply redesign: recent_votes moves from capped Deque/VecDeque with write-time trim to append-only List/Vec with query-time capping, drops projection_apply’s BTreeSet + trim_recent_votes path, and bumps schema with a focused load test. A is a correct, well-tested filter for stickied/pinned Reddit children, but it is a narrow import-side tweak versus B’s lasting core-model simplification.
