Struct CosineProbabilityOperator 

pub struct CosineProbabilityOperator {
    pub source: Arc<dyn Operator>,
}

Marks a vector operator (KNN, threshold, …) for probability-domain evidence conversion. Direct operator execution applies the uncalibrated (1 + score) / 2 bridge from cosine similarity in [-1, 1] to [0, 1] (Definition 7.1.2, Paper 3). At an engine fusion boundary the driver intercepts this marker and fits the Paper 5 query-pool likelihood-ratio transform instead; reusable calibrated models live in uqa_scoring::VectorCalibrationModel.
