DATABASE_MATCH via CultureBotHT

SUPERSEDED (#456): the CAS-selected ChEBI term denotes a different stereochemical form. Original note follows. Imported from CultureBotHT. CAS-RN→CHEBI mapping resolved via OAK CHEBI sqlite (cas xref).

CURATOR_JUDGMENT via MIM curation (#456)

The CultureBotHT label and CAS-RN name the DL/racemic form, while CHEBI:5445 is stereo-unspecified and has separate D and L children. No exact local ChEBI term denotes the racemate. Per MAPPING_SEMANTICS.md Section 3, the record now uses cas:56-82-6 as the exact registry identity plus a narrowMatch to CHEBI:5445.

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 'glyceraldehyde'; it matches the ChEBI synonym 'DL-glyceraldehyde' on CHEBI:5445. 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).
