Struct HeadFitReport 

pub struct HeadFitReport {
    pub status: ConvergenceStatus,
    pub iterations: usize,
    pub final_grad_norm: f64,
    pub objective: f64,
}

Deterministic record of one fit.

Every field is a function of the inputs alone. There is no wall-clock field of any kind: this report is designed to be hashed into a reproducibility record, and a timing field makes any such record irreproducible. Time a fit at the call site if you need it.

Fields

status: ConvergenceStatus

Terminal optimizer status (always Converged when fit returned Ok).

iterations: usize

Iterations performed.

final_grad_norm: f64

Final gradient norm.

objective: f64

Final objective value (mean NLL + penalty).
