Evidence (3)

DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 314041-10-6 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 anchor_cas_hydrate_records

potassium tellurate hydrate is a hydrate/salt with its own CAS and no exact ChEBI term; anchored to the parent CHEBI:30463 'telluric acid' by narrowMatch per MAPPING_SEMANTICS.md Section 3 step 2. potassium salt hydrate of telluric acid (H2O4Te, neutral, 3-STAR). NOT CHEBI:30464 tellurate, which is the (2-) anion: a neutral salt is not a kind of a dianion

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:30463 ('telluric 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.
