DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 13517-23-2 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). FEBA/Hans80 panels: Hans80metals. Curator can promote to a CHEBI primary if/when CHEBI adds the term.

DATABASE_MATCH via anchor_cas_hydrate_records

Sodium phosphite dibasic pentahydrate is a hydrate/salt with its own CAS and no exact ChEBI term; anchored to the parent CHEBI:36361 'phosphorous acid' by narrowMatch per MAPPING_SEMANTICS.md Section 3 step 2. disodium pentahydrate salt of phosphorous acid

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:36361 ('phosphorous 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.
