Struct CompiledBlock 

pub struct CompiledBlock {
    pub t_lw: ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>,
    pub anchor_correction: Option<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>>,
    pub r_lw: Option<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>>,
}

One compiled block: reparam matrix V (t_lw) and the optional anchor correction matrix M that downstream blocks consume as a first-class anchor.

Fields

t_lw: ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>

Orthogonal-complement reparam matrix V ∈ R^{p × p'} (right-selector).

anchor_correction: Option<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>>

Residualised anchor correction M ∈ R^{d_raw × p'} at the compiled width, expressed in raw cumulative-anchor-column coordinates: d_raw is the sum of the raw column counts of every prior block, NOT the (possibly smaller) count of kept anchor directions. The predict-time row contribution is (C(x)·V − A_raw(x)·M)·β, where A_raw(x) is the raw anchor evaluation. None for the first block in the ordering. Synonymous with r_lw.

r_lw: Option<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>>

Residualised reparam R_b = M_b · V_b — what the residualised row evaluator uses to subtract the anchor portion. None for the first block in the ordering (no anchor). Equal to anchor_correction.
