Struct BucketStats 

pub struct BucketStats {
    pub bucket: String,
    pub count: usize,
    pub passed: usize,
    pub pass_rate: f64,
    pub advice: String,
    pub advice_status: AdviceStatus,
}

Per-bucket calibration statistics.

Token economy (1.0.78): advice is skipped when empty — the advice_status enum carries the same signal in a more compact form for the well_calibrated / sample_too_small / unknown_label cases.

Fields

bucket: String

Bucket label (e.g. “low”, “medium”, “high”, “critical”).

count: usize

Total observations assigned to this bucket.

passed: usize

Observations that passed (predictor was right).

pass_rate: f64

Pass rate as a fraction in [0.0, 1.0]. NaN when count == 0 (guard before use). Rounded to 4 decimal places.

advice: String

Plain-English advisory drawn from the gap between bucket label semantics and observed pass rate. Empty string when the bucket appears well-calibrated — skipped in serialization for that case (advice_status carries the signal).

advice_status: AdviceStatus

Why advice looks the way it does. Field-eval refinement (1.0.73 AcmeProj run): an empty advice string had three possible meanings — well-calibrated, sample-too-small, or unknown-label — and consumers couldn’t tell which from the JSON alone. This explicit status lets downstream tools gate alerting / dashboards without re-deriving the classification from count + bucket semantics.
