Both are similar-scope UI feature commits, but Side A introduces the underlying vote-count feature (edge_vote_count_for_pair) plus its unit test, and adds the HUD unpin-via-POST mechanism from scratch, which Side B's commit directly builds upon (reusing next_path, unpin_rpc pattern). Side A thus lays more foundational groundwork with a genuine new capability and test coverage, while Side B mainly extends the same pattern to one more UI location plus test adjustments.
