CHEBI:18420 REJECTED CHEBI EXACT_MATCH

Ontology mapping

Primary identifier
CHEBI:18420
Ontology label
magnesium(2+)

Evidence (1)

CURATOR_JUDGMENT via MIM curation (#631)

CultureMech's source rows explicitly carry KEGG:mg2, so the source label denotes dissolved Mg2+ rather than a neutral magnesium atom.

2026-08-30T10:35:03.361102+00:00 claude_culturemech_residual_grounding CREATED_FROM_CULTUREMECH_RESIDUAL MAPPED Created from a CultureMech recipe ingredient MIM held no record for (3 mentions across 3 recipes). Grounded to CHEBI:25107 ('magnesium atom') on an exact match of an exact synonym to the query 'Magnesium'. Source: culturemech:output/ingredient_occurrences.tsv.
2026-09-06T07:34:56.956907+00:00 claude_restore_culturemech_evidence CORRECTED Added ontology_mapping.evidence recording the CultureMech occurrence table as the source of this grounding. The provenance was already in this record's CREATED_FROM_CULTUREMECH_RESIDUAL history entry but absent from the structured field the SSSOM builder reads, so a rebuild dropped MIM:culturemech:output/ingredient_occurrences.tsv from the published row (#541).
2026-09-11T23:46:36.251078+00:00 fix_element_atom_overclaims MERGED_INTO REJECTED Merged into CHEBI:18420 'Magnesium(2+)'; transferred 3 CultureMech occurrence(s) and dropped the atom-grounded SSSOM row. CultureMech's source rows explicitly carry KEGG:mg2, so the source label denotes dissolved Mg2+ rather than a neutral magnesium atom. (#631).
