Side A turns the previously stubbed-out Reddit import into a real, working feature: a background worker with OAuth token management, rate-limit handling/backoff, dedup, JSON parsing for both subreddits and post listings, wired into the UI, plus solid unit tests for URL mapping and parsing. Side B is a valuable refactor (bridge-based pair suggestion algorithm, ID-normalization fix, morph-based vote UI, test infra cleanup), but it builds on and refines functionality that side A actually introduced, making A's contribution more foundational and self-contained.
