pub fn eval_comparison_truth_with_enum_catalog(
    op: BinaryOp,
    left: &Value,
    right: &Value,
    control: &ProductionControl<'_>,
    enums: Option<&dyn EnumLabelCatalog>,
    state: Option<&EnumComparisonState>,
) -> Result<Option<bool>>

Observe scalar and nested enums through the caller’s catalog, preserving private scalar/row call state, shared type support state and ordinary three-valued rules.
