Struct ProvenanceChain 

pub struct ProvenanceChain {
    pub nodes: Vec<ProvenanceNode>,
}

A causal chain tracking how a block came to exist. Answers: “Agent X produced this because of Y, authorized by Z.”

Fields

nodes: Vec<ProvenanceNode>

Implementations

impl ProvenanceChain

pub fn with_cause(self, cause: CauseKind, actor: ActorId) -> Self

pub fn immediate_cause(&self) -> Option<&ProvenanceNode>

The immediate cause — the last node in the chain.

pub fn root_cause(&self) -> Option<&ProvenanceNode>

The root cause — the first node (usually a human prompt).
