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.
