Commit B is a substantial, coherent feature/refactor: it introduces explicit user-triggered entity fetching, persists full raw API payloads via a new EntityImported event for proper replay, decouples Reddit API base URLs for testability, adds dotenv support, and includes a real integration test with a mock Reddit server plus fixture data. Commit A is a small, well-tested but narrow bugfix (skipping pinned posts) that adds real value but is far more limited in scope and lasting architectural impact compared to B's persistence/import redesign.
