Struct AliasedPair 

pub struct AliasedPair {
    pub block_a: String,
    pub block_b: String,
    pub direction_a: usize,
    pub direction_b: usize,
    pub overlap: f64,
    pub bias_shift: f64,
}

A pair (block_a.column → block_b.column) whose normalised inner product exceeds the alias-overlap reporting threshold. Reported once per audited pair, in block-order (block_a index strictly less than block_b index in the spec list, so the “earlier block carries the image” attribution is well-defined).

Fields

block_a: String

block_b: String

direction_a: usize

direction_b: usize

overlap: f64

|aᵀb| / (‖a‖·‖b‖). Always in [0, 1]. Values at or near 1.0 indicate near-perfect collinearity; values in (threshold, 1.0) indicate partial overlap that the column-pivoted QR will still preserve (only fully redundant directions get pivoted out).

bias_shift: f64

Bias shift applied to the null-distribution mean for this pair, equal to bias_shift_for_pair(z_a, z_b, s2_a, s2_b). Non-zero when exactly one block carries a RowScaledJacobian callback (or the two scalings differ) and the row-scaling vector is skewed. Stored so that the halt-threshold check can apply the same directional correction as the report-threshold check. Zero for all pairs arising from the channel-aware audit path, and for pairs from the flat path when both blocks have symmetric (or absent) row scaling.
