openai/gpt-chat-latest → A (20:1)

Side A makes multiple functional improvements: it correctly passes delegate attribution out-of-band instead of embedding it in DSL text, fixes vote-pair selection by returning no next pair rather than incorrectly falling back to all items when the sibling pool is too small, simplifies the UI by removing the swap button, and consistently renames the public voting route from /vote/compare to /vote across code and tests. Side B only deletes a developer notes file, removing project documentation without adding runtime behavior or architectural value.
