Side B fixes a real bug (Reddit children imports bypassing ensure_path causing wrong path nesting) and a UI defect (unranked children showing raw ids instead of titles), backed by updated integration tests exercising the actual bug. Side A is a legitimate visual improvement (min-max gradient normalization) with good unit tests, but it's a cosmetic refinement rather than a correctness fix affecting data integrity.
