Struct TraceNode 

pub struct TraceNode {
    pub typ: String,
    pub value: f64,
    pub children: Vec<TraceNode>,
    pub left_ref: Option<String>,
    pub right_ref: Option<String>,
}

One node of an evaluation trace — the verdict tree explain returns. Mirrors the expression: typ is the node’s type URI, value its result (1.0/0.0 for booleans), children the operand traces in evaluation order. A short-circuited operand is simply ABSENT from children — the trace is truthful about what ran. Ordered comparisons carry their resolved operand identities as left_ref/right_ref instead of children. This is a runtime return shape, not an ontology class.
