2026-08-24T00:00:00+00:00 regrade_synonym_matches REGRADED_TO_CAS_RN_LOOKUP mapping_quality EXACT_MATCH -> CAS_RN_LOOKUP (#317). The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 696-06-0 uniquely resolves by ChEBI xref to CHEBI:80624 '5,6-Dihydro-5-fluorouracil'. CAS_RN_LOOKUP records the method that established this mapping; a lexical grade would discard that provenance. ontology_id is unchanged. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality.
