# Freedback vocabulary
#
# INVARIANT: this ontology declares STRUCTURE ONLY (subclass / motivation
# relations). It MUST NOT encode validation rules — those live entirely in
# shapes.ttl (SHACL). RDFS/OWL are open-world and monotonic; using them for
# bounds/required would silently infer rather than reject. See
# docs/adr/0004-validation-in-shacl.md.
