Struct PenaltyCandidate 

pub struct PenaltyCandidate {
    pub matrix: Array2<f64>,
    pub nullspace_dim_hint: usize,
    pub source: PenaltySource,
    pub normalization_scale: f64,
    pub kronecker_factors: Option<Vec<Array2<f64>>>,

}

Fields

matrix: Array2<f64>

nullspace_dim_hint: usize

source: PenaltySource

normalization_scale: f64

kronecker_factors: Option<Vec<Array2<f64>>>

Optional Kronecker factors whose product equals matrix. When present, spectral decomposition can be done per-factor (O(Σ q_j³) instead of O((Π q_j)³)).

op: Option<Arc<dyn PenaltyOp>>

Optional operator-form handle whose as_dense() matches matrix. When populated by the closed-form factories, this is propagated through to CanonicalPenaltyBlock so downstream consumers can use exact matvec algebra without rebuilding the dense Gram. When None, only the dense matrix path is available.
