Fields§

§dim: usize§design: DesignMatrix§penalties: Vec<Array2<f64>>§ops: Vec<Option<Arc<dyn PenaltyOp>>>§nullspaces: Vec<usize>§null_eigenvectors: Vec<Option<Array2<f64>>>

Per-active-penalty null-space eigenvector matrices, parallel to penalties / ops / nullspaces. Some(U_null) when nullspaces[k] > 0, with U_null orthonormal columns spanning null(penalties[k]) in this smooth’s local coordinate system; None when the active block is full-rank. Stage 1 plumbing; Stage 2 consumes this to absorb the smooth’s null space into the parametric block at TermCollectionDesign construction.

§joint_null_rotation: Option<JointNullRotation>

Joint-null absorption rotation for this smooth. Some(rotation) records Q = [U_range | U_null] spanning null(Σ_k penalties[k]), the joint null across all active penalty blocks on this smooth. None means the joint penalty is full-rank (joint nullity = 0) or there are no penalties. Stage-2 commit A: plumbing only — populated by commit B, applied by commit D.
