~x-ai/grok-latest → B (2:3)

B fixes a real reducer correctness bug by dropping zero-ratio votes before ensure_item/voted_pairs side effects, preventing ghost items and false voted-pair state; the updated test asserts empty indexes rather than registered no-edge items. A adds useful pool-scoped voting UX (query param, next-pair constraint, “vote on children” entry point) but is feature surface on top of voting, not a core integrity fix.
