| 2026-06-09T05:23:46.757987+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'DL-carnitine' -> 'carnitine': synced to canonical CHEBI label (preferred_term 'DL-carnitine' unchanged). | |
| 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 'carnitine'; it matches the ChEBI synonym 'D,L-carnitine' on CHEBI:17126. 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). | |
