Struct SpectralFrame 

pub struct SpectralFrame {
    pub bands: [f32; 25],
    pub entropy: f32,

}

One position’s spectral reading.

Fields

bands: [f32; 25]

Filterbank EMA: bands[d * N_CLASSES + c] is decay d x class c, each in [0, 1] (fraction of recent bytes in class c at timescale tau_d).

entropy: f32

Rolling Shannon entropy of the local window, normalized to [0, 1].

period: u16

Dominant byte-period of the neighborhood (0 = none detected).

period_strength: f32

Normalized autocorrelation peak height [0, 1].

novelty: f32

k-gram surprise [0, 1] (1 = first sighting in window).

Implementations

impl SpectralFrame

pub fn texture_mix(&self) -> [f32; 5]
