openai/gpt-chat-latest → A (20:1)

Commit A makes multiple user-facing and architectural improvements across the application: it fixes vote page behavior, changes delegate handling by passing the browser agent out-of-band, removes an incorrect fallback when too few sibling items exist, simplifies the UI by removing the swap button, renames routes from /vote/compare to /vote, updates tests, and threads the API change through the codebase. These changes affect functionality, routing, correctness, and maintenance. Commit B only deletes a developer notes file with no direct effect on application behavior or infrastructure. As a result, A contributes substantially more.
