5 SHACL shapes, all sharing the same property-shape blank node (_:b218dcfc815ed) which enforces prov:wasGeneratedBy per the three-criterion class-promotion test. Emitted into opda-descriptive-shapes.ttl.

Shared property shape

The 5 identity-key shapes below all reference the same blank-node property shape:

_:b218dcfc815ed
    sh:message "Class-promoted descriptive Kind MUST carry prov:wasGeneratedBy to its issuing activity per ODR-0008 §Q4a three-criterion test (authority-retrieved provenance is the IC discriminator for class-promotion)."@en ;
    sh:minCount "1"^^xsd:integer ;
    sh:path prov:wasGeneratedBy ;
    sh:severity sh:Violation .

The property shape requires at least one prov:wasGeneratedBy triple on every class-promoted descriptive Kind. This is the IC discriminator that justifies class-promotion per the three-criterion test (authority-retrieved provenance).
