Side A fixes a real design flaw in B's auto-fetch-on-browse behavior by making imports explicit user actions, persists the full API payload through the event log for correct replay/audit (via a new EntityImported event and apply_entity_raw), and adds solid regression tests (replay test, fixture-based Reddit test, and an end-to-end mock-API integration test). Side B is the initial (and reasonable) implementation of the Reddit worker/broker, but it auto-fetches on every browse without persisting raw payloads, which A explicitly corrects and extends with more durable, testable design.
