OntologyAttribute

One entity attribute as the catalog shows it. key is server-derived from the EntityType schema (metadata.keys) and can never be hidden — the join axis has to stay in the frame. visible=False narrows the LLM surface only (catalog / match / result frame); traversal still reads the column. dictionary sits on the display attribute people type, never on the key: a matched surface resolves to the key (D6 — measured 0/2 with the dictionary on the key, the model matches aliases on label). description is imported from the EntityType field's metadata.description and may be overridden by curation, which is what a model whose fields carry no metadata depends on: without it the catalog hands the LLM a bare physical name (hbp_knd_cd) and the only way to learn what its codes mean is to query for them. values / samples are the value-grounding pair Column already has and carry the same meanings — values the exhaustive low-card domain, samples illustrative examples that ground the literal format. Both are curator-owned: an EntityType schema has no such concept, so an import never supplies them and a sync never overwrites them. Both are suppressed in the catalog for a dictionary-backed attribute, exactly as they are on a column, because one leaked canonical code primes the model to emit codes instead of surface forms.
