    "description": "A URI identifying the workflow definition (the code that ran) behind a runs entry, as opposed to the workflow declaration identified by `workflow_declaration_uri`.\nA typical value is a git URI pinned to a full commit hash, of the form `git+https://host/path@<commit>#<subdir>`.\nNo particular URI scheme or resolvability is mandated, but providers SHOULD use a URI that pins the exact code revision.\nNull is expected when the executed code is unknown, e.g., for legacy data.",
