Side A introduces substantial, lasting functionality: it redesigns identity around UUIDs with OAuth account linking, adds Reddit OAuth support end-to-end (routes, provider implementation, callbacks, UI, storage queries), and fixes trust-weight projection batching by tracking pending writes. Side B is a focused test infrastructure repair, correcting mock HTTP behavior (query parsing, request body reading, redirects, null handling) and updating test selectors so end-to-end auth tests run again, but it primarily supports development rather than changing core project capabilities.
