DATABASE_MATCH via CultureMech

SUPERSEDED (#315): describes the bare ion identity, not the complete salt or ion pair. Original note follows. Imported from CultureMech pipeline, quality=DIRECT_MATCH

CURATOR_JUDGMENT via MIM curation (#315)

The label names sodium crotonate, not the crotonate anion in CHEBI:35899; CHEBI:41131 is the ChEBI acid parent. No exact local ChEBI term for 'Na-crotonate' was found, so MAPPING_SEMANTICS.md Section 3 uses a kgmicrobe.compound identity with the nearest ChEBI parent.

2026-09-11T06:31:23.789310+00:00 fix_salt_ion_identity_overclaims REGROUNDED_ION_OVERCLAIM MAPPED identifier CHEBI:35899 -> kgmicrobe.compound:na-crotonate; mapping_quality -> NARROW_MATCH to CHEBI:41131 ('crotonic acid'). Cleared chemical_properties because they described the crotonate anion only, marked 12 bare-ion synonym(s) as REJECTED_LABEL, and kept the complete salt or ion-pair identity distinct (#315).

Deleted source had upstream source_id=mediadive.ingredient:2053. Deleted source also carried Edison literature identity review: sodium crotonate was a defined sodium carboxylate/aqueous sodium-crotonate preparation with no ontology CURIE proposed.
