| 2026-06-09T05:23:46.757581+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Dithionite' -> 'dithionite(2-)': synced to canonical CHEBI label (preferred_term 'Dithionite' unchanged). | |
| 2026-07-20T00:00:00+00:00 | migrate_media_roles_to_facets | ANNOTATED | Migrated legacy media_roles to role facets (#128): REDUCING_AGENT -> physicochemical_roles.REDUCING_AGENT | |

The record's label does not equal the term's primary label 'dithionite(2-)'; it matches the ChEBI synonym 'dithionite' on CHEBI:42160. 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). | |
