TreeRegressionResult

@Serializable
@SerialName(value = "TreeRegressionResult")
data class TreeRegressionResult(val root: TreeNodeResult) : Result(source)

Immutable snapshot of a RegressionTree at read time. Carries the tree structure (split predicates + per-node weighted-variance aggregates) so callers can route a context vector to its leaf without reaching back into the live stat.

The root's WeightedVarianceResult is exposed as the canonical scalar snapshot; callers wanting context-specific predictions use findLeaf or predict.
