Struct CoherenceMeasure 

pub struct CoherenceMeasure {
    pub alignment: f64,
    pub disagreement: Vec<f64>,
    pub dominant_mode: Vec<f64>,
}

Measures how well a belief assignment aligns across the sheaf.

Alignment = 1 - ||L_F x|| / ||x|| (higher = more coherent). Per-edge disagreement = ||F_{ij} x_i - F_{ij} x_j|| where F_{ij} is the restriction map. Dominant mode = eigenvector of the smallest nonzero eigenvalue (most coherent non-trivial pattern).

Fields

alignment: f64

Overall alignment score: 1 - ||L_F x|| / ||x||.

disagreement: Vec<f64>

Per-edge disagreement values.

dominant_mode: Vec<f64>

Eigenvector of smallest nonzero eigenvalue.
