Side A fixes a real functional bug (pinned posts polluting imports) with a targeted code change plus a test verifying both stickied and pinned fields are handled. Side B is a config simplification for test discovery that reduces maintenance friction but carries risk (auto-discovery could unintentionally pick up unwanted namespaces) and has no functional/test-of-behavior impact on the product itself.
