#![forbid(unsafe_code)]
#![deny(missing_docs)]
//! Discrete spectral atlas.
//!
//! This crate hosts the Fast Walsh-Hadamard Transform framed as the Fourier /
//! character transform of the boolean hypercube group `(Z/2)^n`: FWHT / IFWHT,
//! XOR convolution, subset zeta / Mobius transforms, Walsh signatures, and an
//! implicit Hadamard matrix view. Music is a downstream consumer; no music type
//! ever appears here.
//!
//! Boundary: depends on `sim-lib-discrete-algebra`; never on `sim-lib-music-*`.
