Struct ArrowFactorSlab 

pub struct ArrowFactorSlab { /* private fields */ }

Per-row + Schur Cholesky factor cache produced by solve_arrow_newton_step_with_options. Consumed downstream by the IFT warm-start predictor in crate::persistent_warm_start: when the outer loop perturbs (β, ρ) by a small amount, the new Newton step can be predicted by re-using these factors against a refreshed RHS, saving the dominant O(N d³ + K³) factorization cost.
