Struct StratifiedNestedCvSpec 

pub struct StratifiedNestedCvSpec {
    pub splitter: StratifiedKFoldSpec,
    pub strata: BTreeMap<SampleId, String>,
}

Nested stratified K-fold with the identity-keyed class labels required to construct folds inside each outer-training universe.

Keeping the labels on the fingerprinted policy lets the coordinator build every inner fold without inspecting feature buffers or asking a model controller to reinterpret target rows. Labels for outer-validation samples may be present, but NestedCvSpec::build_nested_fold_set selects only the owning outer fold’s training ids before splitting.

Fields

splitter: StratifiedKFoldSpec

strata: BTreeMap<SampleId, String>
