# Slot: experiment_yaml_hash 


_SHA-256 hex digest of the normalised experiment YAML that produced this artifact. Used by the cross-experiment cache (see :class:`SimulationStudy.from_file`) to detect when a cached upstream result has gone stale because the experiment's spec was edited. Computed as ``hashlib.sha256(yaml.safe_dump(normalized_yaml).encode()).hexdigest()`` over the fully resolved (post-``!include``) experiment block._
