    No deprecation policy, no Sunset or Deprecation header, and no notice
    channel. A plugin or theme change on the corporate site can remove a
    namespace or a custom post type without warning — this is the principal
    stability risk in consuming this surface.

    CONSOL Energy Inc. and Arch Resources completed an all-stock merger of
    equals forming Core Natural Resources, Inc. (NYSE: CNR). The SEC registrant
    CIK 0001710366 is the surviving CONSOL entity renamed; consolenergy.com
    301-redirects to corenaturalresources.com, and the mine roster served by the
    content API contains both legacy fleets (Bailey, Enlow Fork, Harvey from
    CONSOL; Black Thunder, West Elk, Leer from Arch).
