    "Translation locale, learning language, interface locale and annotation capability are independent.",
    "A learning language may publish reviewed Frame extensions before annotation or interface localization exists.",
    "A stable Pattern Frame may resolve to itself or to one explicit canonical Frame.",
    "A FrameVariant relation never deletes, renames or rewrites the stable Pattern ID that produced it.",
    "Canonical Frame grouping is published only from the explicit reviewed-pilot manifest; audit similarity alone cannot create a family.",
    "Canonical Frame membership is language-specific and does not imply cross-language equivalence; Bridges remain separate reviewed relations."
