    "wue": "The instrument sets the A-G grade from PUE and WUE together, but this pack ships only the PUE bands, because only those were read from the instrument text. Inventing WUE boundaries to complete the set would be precisely the failure BandingScale exists to prevent: a threshold with no provenance, presented as if it had one. A composite grade built from this pack alone covers one axis, and CompositeRating::covers reports that it does."

  "caveats": [
    "A grade produced from this scale is NOT a regulatory determination. The instrument is a draft; its thresholds may change before adoption, and the scheme's own assurance requirements are not modelled here.",
    "The instrument permits measurement AND calculation methods, with an explicit fallback to well-founded assumptions and estimates. A PUE fed to this scale may therefore be self-declared. The scale bands whatever number it is given and says nothing about how that number was acquired — carry the acquisition class alongside it.",
    "This pack supersedes no earlier reading. If the adopted instrument differs, that is a NEW scale_id (eu.eed.dr2026.pue/2 or a successor), never an edit to this file: ratings cite the scale_id, so editing in place would silently re-band every grade already issued."
