Struct FlakeConfig 

pub struct FlakeConfig {
    pub alpha: f64,
    pub lambda: f64,
    pub sigma: f64,
    pub variance_window: usize,
    pub min_observations: usize,
    pub enable_logging: bool,
    pub threshold: Option<f64>,
}

Configuration for the flake detector.

Fields

alpha: f64

Significance level α. Fail when E_t > 1/α. Lower α → more conservative (fewer false alarms). Default: 0.05.

lambda: f64

Betting intensity λ. Higher values detect deviations faster but are more sensitive to noise. Default: 0.5.

sigma: f64

Prior estimate of standard deviation for latency residuals. Used in the e-value formula. Default: 1.0 (normalized units).

variance_window: usize

Rolling window size for empirical variance estimation. Set to 0 to use fixed sigma. Default: 50.

min_observations: usize

Minimum observations before making decisions. Helps with warm-up. Default: 3.

enable_logging: bool

Enable JSONL-compatible evidence logging. Default: false.

threshold: Option<f64>

Minimum e-value before flagging as flaky (1/alpha). Computed from alpha but can be overridden.
