Struct ExperimentSessionReport 

pub struct ExperimentSessionReport {
    pub session_id: SessionId,
    pub results: Vec<ExperimentResult>,
    pub best_config: ConfigSnapshot,
    pub baseline_score: f64,
    pub final_score: f64,
    pub total_improvement: f64,
    pub wall_time_ms: u64,
    pub cancelled: bool,
}

Final report produced by ExperimentEngine::run.

total_improvement can be negative if no variation improved the baseline, or NaN if the baseline evaluation itself returned NaN (which causes an early EvalError rather than a report).

Fields

session_id: SessionId

Session ID generated at ExperimentEngine construction time.

results: Vec<ExperimentResult>

All variation results recorded in this session (both accepted and rejected).

best_config: ConfigSnapshot

The best-known config snapshot at session end (may equal the initial baseline).

baseline_score: f64

Baseline mean score captured before the variation loop started.

NaN when the session was cancelled before the baseline evaluation completed.

final_score: f64

Mean score of the best-found configuration at session end.

NaN when the session was cancelled before the baseline evaluation completed.

total_improvement: f64

final_score - baseline_score (positive means improvement over baseline).

wall_time_ms: u64

Total wall-clock time for the session in milliseconds.

cancelled: bool

true when the session was stopped via ExperimentEngine::stop or a CancellationToken before the variation loop completed naturally.
