Struct Evaluation 

pub struct Evaluation {
    pub sessions: u64,
    pub mean: f64,
    pub ucb: Option<f64>,
    pub units: u64,
    pub ess: f64,
    pub max_weight: f64,
    pub truncated: u64,
}

The monitor’s weighted estimate (select/policy.rs Monitor), the auto-revert’s evidence, and how far it can be trusted.

Fields

sessions: u64

The learned policy’s sessions it read.

mean: f64

Per apply, (policy − fixed rule) + α × the fixed rule’s value, and the confidence sequence’s upper bound on it (None until enough sessions): below 0 the store reverts to the fixed rule.

ucb: Option<f64>

units: u64

The labelled units weighed, and their effective number ((Σw)² / Σw²).

ess: f64

max_weight: f64

The largest weight against the mean weight.

truncated: u64

The units whose weight was truncated.
