DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 14919-49-4 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). Curator can promote to a CHEBI primary if/when CHEBI adds the term.

DATABASE_MATCH via MESH via OLS (label-exact)

Parent class identified via label-exact; matched_via="3,4'-Dihydroxyflavone"

MANUAL_CURATION via MIM curation (#312); chebi.db

identifier cas:14919-49-4 -> mesh:C559991; ontology mesh:C559991 ('3,4'-dihydroxyflavone') -> mesh:C559991 ('3,4'-dihydroxyflavone'); mapping_quality NARROW_MATCH -> EXACT_MATCH. mesh.db gives MESH:C559991 the label "3,4'-dihydroxyflavone", identical to the record's label and distinct from MESH:C028288 "3',4'-dihydroxyflavone". chebi.db has no term for this compound (CAS 14919-49-4 and the name resolve to nothing). A broadMatch from a record to the same compound is false; Section 3 step 1 makes the MeSH term the identifier (68 records already carry mesh: primaries) with EXACT_MATCH. The CAS stays in chemical_properties and on its registry row; the kgmicrobe.compound row is dropped as #326 did for 72-Dihydroxyflavone.
