Struct NodeRegistration 

pub struct NodeRegistration {
    pub deps: Vec<NodeId>,
    pub fn_or_op: Option<NodeFnOrOp>,
    pub opts: NodeOpts,
}

Unified node-registration descriptor (D030, Slice D).

All node kinds (State / Producer / Derived / Dynamic / Operator) register through Core::register with a NodeRegistration. The kind is derived from the field shape of the registration — (deps.is_empty(), fn_or_op variant):

deps	fn_or_op	is_dynamic	resulting kind
empty	None	-	State
empty	Some(Fn)	-	Producer
non-empty	Some(Fn)	false	Derived
non-empty	Some(Fn)	true	Dynamic
non-empty	Some(Op)	-	Operator

The sugar wrappers (Core::register_state, Core::register_producer, etc.) build a NodeRegistration and delegate.

Fields

deps: Vec<NodeId>

Upstream deps in declaration order. Empty for state / producer.

fn_or_op: Option<NodeFnOrOp>

Closure-form fn id or typed-op discriminant. None for state / passthrough.

opts: NodeOpts

Cross-kind config knobs.
