Side A makes a substantive storage-model redesign by replacing the durable recent-votes deque with an append-only list, removing post-commit trimming, updating the reducer and load path to apply the cap at query time, bumping the schema version, and adding a regression test for the new behavior. Side B mainly improves authentication UX by returning HTML fragments for inline form updates and extending the generic form JavaScript, which is useful but more localized and less foundational than the persistence-layer change.
