Module comparison 

Differential comparison of two byte streams.

All functions operate on raw &[u8] — no session I/O, no formatting. The CLI layer handles loading, printing, and serialization.

Two-sample philosophy

Per-stream metrics (Shannon H, autocorrelation, etc.) are computed by analysis::full_analysis and displayed side-by-side by the CLI. This module adds cross-stream statistics that directly test whether two byte streams differ: two-sample KS, chi-squared homogeneity, Cliff’s delta, and Mann-Whitney U.

Structs

AggregateDelta

Aggregate statistics delta between two streams.

ComparisonResult

Full comparison result between two byte streams.

DigramAnalysis

Digram (byte bigram) chi-squared uniformity.

MarkovAnalysis

Per-bit Markov transition probabilities.

MultiLagAnalysis

Autocorrelation at multiple lags.
