DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 6382-01-0 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). FEBA/Hans80 panels: FEBA_carbon, FEBA_nitrogen. Used in 44 CultureBot media; samples: Hans Basal Media plus 0.2x 20AA mix, ZMB Gut, SGW Northen Exometabolite mix 5x…. 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='L-Glutamic acid monopotassium salt monohydrate'

DATABASE_MATCH via MIM curation (#342)

mapping_quality NARROW_MATCH -> CLOSE_MATCH, predicate skos:narrowMatch -> skos:closeMatch. narrowMatch asserts this record is *narrower in meaning* than CHEBI:16015 ('L-glutamic acid') — 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.
