Struct ExperimentResult 

pub struct ExperimentResult {
    pub id: i64,
    pub session_id: SessionId,
    pub variation: Variation,
    pub baseline_score: f64,
    pub candidate_score: f64,
    pub delta: f64,
    pub latency_ms: u64,
    pub tokens_used: u64,
    pub accepted: bool,
    pub source: ExperimentSource,
    pub created_at: String,
}

Persisted record of a single variation trial.

Each time ExperimentEngine evaluates a candidate variation, it produces an ExperimentResult that is stored in SQLite (when memory is configured) and included in the ExperimentSessionReport.

Fields

id: i64

Row ID in the SQLite experiments table (-1 when not yet persisted).

session_id: SessionId

Session ID of the experiment session that produced this result.

variation: Variation

The parameter variation that was tested.

baseline_score: f64

Mean score of the current progressive baseline before this variation was tested.

candidate_score: f64

Mean score achieved by the candidate configuration.

delta: f64

candidate_score - baseline_score (positive means improvement).

latency_ms: u64

Wall-clock latency for the candidate evaluation in milliseconds.

tokens_used: u64

Total tokens consumed by judge calls during the candidate evaluation.

accepted: bool

Whether this variation was accepted as the new baseline.

source: ExperimentSource

How this experiment was triggered.

created_at: String

ISO-8601 timestamp when the result was recorded.
