openai/gpt-chat-latest → B (3:2)

Side B makes a substantive architectural change by replacing the persistent recent-vote deque with an append-only list, removing post-apply trimming, capping results at read time, updating the schema version, and adding a regression test that verifies query-time limiting. Side A bundles several useful UI and routing fixes (passing delegate attribution out-of-band, preventing an incorrect fallback when sibling pools are too small, simplifying navigation, and renaming `/vote/compare` to `/vote`), but much of the patch is route and UI churn rather than a deeper storage design improvement.
