Struct PerSupernodeStats 

pub struct PerSupernodeStats {
    pub snode_id: usize,
    pub front_size: usize,
    pub num_fully_summed: usize,
    pub num_eliminated: usize,
    pub num_delayed: usize,

}

Per-supernode diagnostic statistics.

Collected during AptpNumeric::factor for each supernode processed. Provides visibility into per-front behavior for analysis and comparison with reference solvers (e.g., SPRAL).

Fields

snode_id: usize

Supernode index in postorder.

front_size: usize

Frontal matrix dimension (m).

num_fully_summed: usize

Number of fully-summed rows/columns (k = supernode cols + delayed from children).

num_eliminated: usize

Number of columns successfully eliminated (ne <= k).

num_delayed: usize

Number of delayed columns (k - ne).

num_1x1: usize

Number of 1x1 pivots accepted at this supernode.

num_2x2: usize

Number of 2x2 pivot pairs accepted at this supernode.

max_l_entry: f64

Maximum absolute L entry at this supernode (stability metric).
