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 'ethylenediaminetetraacetatoferrate(1-)'; it matches the ChEBI synonym 'Fe(III)-Edta' on CHEBI:30729. 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).
