Reported and source-standardized fields are displayed separately and retain their exact lexical values. The standardized field does not overwrite the upstream report.
No cross-assay comparison is authorized by this record. Evaluate target, construct, endpoint, relation, units, assay format, conditions, and exact molecular form first.

Snapshot provenance
Each retained corpus build input is identified by retrieval time, snapshot path, SHA-256 digest, and exact upstream request. The snapshot files are not embedded in the served binary; the provenance identifiers remain dependencies of this one admitted record, not interchangeable citations.
