Side A introduces the entire Reddit fetching subsystem from scratch (background worker, rate-limit/backoff, OAuth token handling, JSON parsing for posts/subreddits, wiring into AppState/UI, plus tests), representing substantial new lasting functionality. Side B is a smaller, valuable but incremental fix on top of that existing system (forcing OAuth, retry-on-401/403, error message cleanup), which is real but narrower in scope compared to the foundational architecture A establishes.
