DATABASE_MATCH via MIM curation (#321/#334)

identifier CHEBI:172950 -> kgmicrobe.compound:dl-isocitric_acid_trisodium_salt_hydrate; mapping_quality EXACT_MATCH -> NARROW_MATCH. The record is a hydrate of CHEBI:172950 ('Isocitric acid, DL-') and was sharing that term's identifier — the identity collapse MAPPING_SEMANTICS §3 forbids, which made a distinct substance indistinguishable from its anhydrous parent downstream. ChEBI has no term for this hydrate and the record carries no verified CAS, so steps 1 and 2 are unavailable and step 3 applies.

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:172950 ('Isocitric acid, DL-') — 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.
