A adds an end-to-end pool-scoped voting path (optional pool query, pair pick from children, constrained next-pair nav, UI entry point, and pool threaded through VoteComparePost/success JS), which is lasting product design. B is a real but narrower fix: Reddit children attach via apply_entity_under_parent instead of ensure_path/link_child, titles in unranked labels, and test updates—correct and necessary, but smaller in scope than A’s full workflow.
