Interpretation boundary

This record represents an experimentally determined structure, not a predicted model. A co-crystal ligand, if present upstream, does not by itself establish affinity. This record does not infer kinetics, pathway rate, or metabolic flux.

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.
