Evidence (3)
Imported from CultureBotHT. CAS-RN 120618-65-7 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). FEBA/Hans80 panels: Hans80metals, FEBA_stress. Curator can promote to a CHEBI primary if/when CHEBI adds the term.
Ceftazidime hydrate is a hydrate/salt with its own CAS and no exact ChEBI term; anchored to the parent CHEBI:3508 'ceftazidime' by narrowMatch per MAPPING_SEMANTICS.md Section 3 step 2. unspecified hydrate of ceftazidime; CHEBI:3509 is specifically the pentahydrate, which the label does not claim
mapping_quality NARROW_MATCH -> CLOSE_MATCH, predicate skos:narrowMatch -> skos:closeMatch. narrowMatch asserts this record is *narrower in meaning* than CHEBI:3508 ('ceftazidime') — a subsumption ChEBI itself denies: it files hydrates under CHEBI:35505 'hydrate', never under the anhydrous compound, which is not an ancestor even transitively. A hydrate is a distinct substance containing the anhydrous form, not a specialization of it. closeMatch claims similarity without subsumption. The ontology_id and the record's own identifier are unchanged.
