Expand description

The result of evaluating a candidate policy against logged traffic.

Fields§

§n_traces: usize

Total traces in the store for this tenant.

§n_evaluable: usize

Traces for which replay used only logged attempts (coverage numerator).

§coverage: f64

n_evaluable / n_traces (1.0 when n_traces == 0).

§est_cost_per_request: f64

Mean candidate cost per request, over evaluable traces.

§logged_cost_per_request: f64

Mean actual (logged) cost per request, over the same evaluable traces.

§est_served_failure: Option<f64>

Estimated served-failure rate over evaluable traces with known correctness. None if no evaluable trace has deferred feedback on the same served rung.

§n_correctness_known: usize

Number of evaluable traces where correctness is attributable from deferred feedback.

§escalation_rate: f64

Fraction of evaluable traces where candidate escalated past the first ladder rung.

§ci_cost: (f64, f64)

Bootstrap 95% CI (2.5/97.5 pct) for est_cost_per_request.

§ci_served_failure: Option<(f64, f64)>

Bootstrap 95% CI for est_served_failure. None when est_served_failure is None.
