| 2026-05-11T06:02:00Z | mediaingredientmech-agentic-curation LLM | CURATED_CHEBI_EXACT_MATCH | MAPPED | Mapped to CHEBI:31793 magnesium carbonate using OAK/OLS exact synonym evidence for MgCO3 in the raw source label. |
| 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 'magnesium carbonate'; it matches the ChEBI synonym 'MgCO3' on CHEBI:31793. 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). |
