Imported from CultureBotHT. CAS-RN 312693-63-3 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.
Maltotriose hydrate is a hydrate/salt with its own CAS and no exact ChEBI term; anchored to the parent CHEBI:61993 'maltotriose' by narrowMatch per MAPPING_SEMANTICS.md Section 3 step 2. unspecified hydrate of maltotriose
mapping_quality NARROW_MATCH -> CLOSE_MATCH, predicate skos:narrowMatch -> skos:closeMatch. narrowMatch asserts this record is *narrower in meaning* than CHEBI:61993 ('maltotriose') — 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.
