DATABASE_MATCH via MIM curation (#213)

SUPERSEDED (#308): the recorded CLOSE_MATCH rationale reads 'the label lost the second locant'. The label no longer lacks it, so that wording is stale; CLOSE_MATCH still stands because 4,4'-dihydroxybiphenyl and biphenyl-4,4'-diol are alternative names, not an exact label match. Original note follows. '4-dihydroxy-biphenyl' is a truncation: a dihydroxy biphenyl needs two locants, and 4,4'-dihydroxybiphenyl is the compound. CLOSE_MATCH because the label lost the second locant, matching the treatment of 3-butanediol and 2-dimethylsuccinic acid earlier in this issue (#213).

2026-08-06T00:00:00+00:00 promote_resolved_unmapped PROMOTED_TO_MAPPED MAPPED Promoted UNMAPPED_0790 -> CHEBI:34367 "biphenyl-4,4'-diol" (CLOSE_MATCH); mapping_status UNMAPPED -> MAPPED, SSSOM row added.
2026-08-08T00:00:00+00:00 apply_locant_corrections CORRECTED_TRUNCATED_LABEL preferred_term '4-dihydroxy-biphenyl' -> "4,4'-dihydroxybiphenyl". The source label lost its locant list to a comma-splitting bug in the microbedecoder ingest (#308); '4-dihydroxy-biphenyl' is not a possible chemical name. The ontology mapping was already correct and is unchanged. Verified: OLS4 CHEBI:34367 label="biphenyl-4,4'-diol", not obsolete; 4,4'-dihydroxybiphenyl is the same compound under an alternative name, so mapping_quality CLOSE_MATCH is left as is.
