Struct NodeDescribe 

pub struct NodeDescribe {
    pub type: NodeTypeStr,
    pub status: NodeStatus,
    pub value: Option<DescribeValue>,
    pub deps: Vec<String>,
    pub operator_kind: Option<String>,
    pub meta: Option<Value>,
}

Per-node descriptor.

operator_kind: Option<String>

Operator discriminant (e.g. "map"); None for non-operators.

meta: Option<Value>

Free-form metadata per canonical Appendix B. Always None in this slice (metadata-storage primitive not yet shipped).
