Enum BootstrapIntegrityAlert 

pub enum BootstrapIntegrityAlert {
    Clean,
    PsdNonFlat {
        flatness_score: f32,
        threshold: f32,
    },
    MeanShift {
        deviation: f32,
    },
    VarianceShift {
        deviation: f32,
    },
}

Outcome of a pre-calibration bootstrap integrity check.

Returned by check_bootstrap_integrity before an admissibility envelope is locked. A non-BootstrapIntegrityAlert::Clean result means the calibration window contains organised structure and should be rejected; the engine must not lock the envelope until a clean window is found.

This directly addresses the “Bootstrap Paradox” panel criticism (paper §L \textit{Pre-emptive Technical Defence}, item 6): if the South China Sea calibration window is already jammed, spectral non-flatness will manifest as a non-zero lag-1 autocorrelation (Wiener-Khinchin) and this alert fires.

Examples

use dsfb_rf::stationarity::{check_bootstrap_integrity, StationarityConfig, BootstrapIntegrityAlert};
let clean: Vec<f32> = (0..64).map(|i| 0.5 + 0.01 * (i as f32 % 7.0 - 3.0)).collect();
assert_eq!(check_bootstrap_integrity(&clean, &StationarityConfig::default()),
           BootstrapIntegrityAlert::Clean);

Variants

Clean

Calibration window passed all WSS and PSD flatness tests. Safe to lock.

PsdNonFlat

PSD flatness test failed: lag-1 autocorrelation exceeded the configured threshold. The window likely contains periodic interference.

Fields

flatness_score: f32

Measured |lag-1 autocorrelation|.

threshold: f32

Configured maximum before alert fires.

MeanShift

Mean stationarity test failed: the half-window means diverge.

Fields

deviation: f32

Normalised |mean first_half − mean second_half| / max(|mean|, ε).

VarianceShift

Variance stationarity test failed: the half-window variances diverge.

Fields

deviation: f32

Normalised |var first_half − var second_half| / max(var, ε).
