Side A implements a substantial new Reddit integration: it adds an asynchronous background fetch broker with request deduplication, OAuth support, rate-limit/backoff handling, JSON parsing into project entities, automatic fetch triggering from browsing and item creation, and supporting tests. Side B contains useful refactoring and new pairwise voting UI logic (including pair selection, morph updates, and item ID normalization), but much of it reorganizes or extends existing UI behavior, whereas Side A introduces a major new subsystem with lasting functionality.
