Struct FitGeometry 

pub struct FitGeometry {
    pub coefficient_gauge: Gauge,
    pub penalized_hessian: UnscaledPrecision,
    pub working: Option<WorkingGeometry>,
}

Coefficient geometry retained at convergence for inference and post-fit diagnostics.

The saved coefficient blocks are always in the raw reporting frame. The geometry may occupy a smaller active frame; coefficient_gauge is the required affine map β_saved = T θ_active + a connecting the two.

Fields

coefficient_gauge: Gauge

Exact affine lift from the active geometry coordinates (the columns of T) to the saved/raw coefficient blocks (the rows of T). This field is intentionally required on the wire: models saved before the active-frame schema must be regenerated rather than guessed as identity.

penalized_hessian: UnscaledPrecision

Joint penalized Hessian H = X'W_HX + S(λ) at convergence, in the active coordinates of coefficient_gauge (dimension coefficient_gauge.reduced_total()). Stored as [UnscaledPrecision] so the dispersion-ownership invariant (this matrix is not φ-scaled) is enforced at the type level.

working: Option<WorkingGeometry>

Optional owned row-wise diagonal IRLS evidence. None is a typed statement that the terminal solver geometry has no single diagonal row representation; it is never represented by empty or zero-filled placeholder vectors.
