Struct EarlyStoppingRecord 

pub struct EarlyStoppingRecord {
    pub schema_version: u32,
    pub node_id: NodeId,
    pub phase: Phase,
    pub fold_id: Option<FoldId>,
    pub metric_role: MetricRoleReference,
    pub best_iteration: u64,
    pub observed_iterations: u64,
    pub best_value: f64,
    pub stopped_early: bool,
    pub record_fingerprint: String,
}

Controller-reported early-stopping outcome, kept separate from persisted OOF/reporting scores and bound to one exact metric role and task scope.

Fields

Zero-based iteration at which best_value was observed.

observed_iterations: u64

Number of completed iterations observed by the monitor.
