Struct ConsistencyDef 

pub struct ConsistencyDef {
    pub model: String,
    pub k: u32,
    pub threshold: f64,
}

Configuration for a self-consistency uncertainty gate: resample the original request k times on the same model and score the candidate by agreement with the fresh samples.

Research basis: Wang et al. 2022 (self-consistency) and Farquhar et al., Nature 2024 (semantic entropy). Answers a model reliably reproduces are far likelier correct; disagreement flags hallucination. This produces a continuous confidence score the conformal threshold machinery can calibrate.

maker == checker is intentional — unlike a judge gate, self-consistency is definitionally self-referential. This is the mechanism, not a bug.

Fields

model: String

The model used for resampling, as provider/model. May equal the candidate’s model — self-consistency is self-referential by design.

k: u32

Number of resample calls. Must be in [2, 8]; defaults to 3.

threshold: f64

Pass iff the mean agreement score ≥ this threshold, in [0, 1].
