DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 1981-58-4 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). FEBA/Hans80 panels: Hans80Anti. Curator can promote to a CHEBI primary if/when CHEBI adds the term.

DATABASE_MATCH via CHEBI via OLS (stem-substring)

Parent class identified via stem-substring; matched_via='Sulfamethazine sodium salt'

DATABASE_MATCH via MIM curation (#322)

narrowMatch parent CHEBI:26714 ('sodium salt') -> CHEBI:102265 ('sulfamethazine'). The previous parent was the class of all sodium salts: it retained the counterion and discarded the compound, collapsing unrelated ingredients onto one node. Chosen because it is the compound the label names. The record stays cas-primary per MAPPING_SEMANTICS §3 step 2; only the parent moves.
