Struct ColumnLineageDatasetFacet 

pub struct ColumnLineageDatasetFacet {
    pub base: BaseFacet,
    pub fields: BTreeMap<String, FieldLineage>,
    pub dataset: Vec<InputField>,
}

How an output dataset’s fields derive from input dataset fields.

Keyed by output field name; the spec defines this facet on output datasets (consumers ignore it on inputs). Fed by the positional plan resolution in crate::column.

Fields

base: BaseFacet

Common facet fields (_producer, _schemaURL).

fields: BTreeMap<String, FieldLineage>

Output field name -> the input fields it derives from.

dataset: Vec<InputField>

Dataset-level (whole-row) influences not tied to a single output column.
