  "description": "Structural schema for this lab's local evaluation artifact, not a wire input for the separate LLMOps release-gate lab. validate_artifact checks only self-consistency; oracle agreement, evidence freshness, and authenticity require trusted recomputation of the pipeline. A versioned adapter must declare and verify the digest profile plus release/source/index/auth lineage before a cross-boundary gate can consume it; cross-boundary authenticity additionally requires a MAC or signature.",
