Struct SpectralPhiEngine 

pub struct SpectralPhiEngine { /* private fields */ }

Spectral Φ approximation using the Fiedler vector.

Computes the second-smallest eigenvalue of the Laplacian of the TPM’s mutual information graph. The Fiedler vector gives an approximately optimal bipartition in O(n² log n) time.
