2026-08-10T00:00:00+00:00	regrade_synonym_matches	REGRADED_EXACT_TO_SYNONYM		mapping_quality EXACT_MATCH -> SYNONYM_MATCH (#317). The record's label does not equal the term's primary label 'beta-D-cellohexaose'; it matches the ChEBI synonym 'Cellohexaose' on CHEBI:49533. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The SSSOM predicate is unaffected (both grades emit skos:exactMatch).
2026-08-24T00:00:00+00:00	regrade_synonym_matches	REGRADED_TO_CAS_RN_LOOKUP		mapping_quality SYNONYM_MATCH -> CAS_RN_LOOKUP (#317). The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 2478-35-5 uniquely resolves by ChEBI xref to CHEBI:49533 'beta-D-cellohexaose'. 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.
