Struct ProbeConfig 

pub struct ProbeConfig {
    pub k: u32,
    pub sample_rate: f64,
}

Shadow-probe configuration (ADR 0008 Phase 1): measure the validated k-sample gate-pass-count signal on a sampled fraction of requests WITHOUT changing serving.

Cost caveat: sample_rate × k extra model calls (at the start_rung model) per sampled request — measurement only, nothing served changes. Default absent = off = zero extra provider calls, byte-identical to today. Enable only when you want to collect the regime signal for offline analysis.

Fields

k: u32

Number of parallel probe samples per request. Must be in [2, 8]; validated by Config::parse. Each sample is one model call at the start_rung model.

sample_rate: f64

Fraction of requests that trigger the probe, in [0, 1]. 0.0 = never; 1.0 = always. Must be finite; validated by Config::parse.
