Enum FrailtyScale 

pub enum FrailtyScale {
    Fixed {
        sigma: f64,

    Learned {
        initial_sigma: f64,
    },
}

Frailty modifier specification at the family level.

Two structurally different exact modifiers exist:

1. GaussianShift: additive Gaussian on the final transformation index. Exact for probit families — the existing sextic microcell kernel survives unchanged (just scale denested cell coefficients by 1/√(1+σ²)).

2. HazardMultiplier: lognormal multiplier on the loaded cumulative hazard. Exact for PH/cloglog families — row likelihoods are finite sums of K_{k,m}(μ, σ) kernel terms.

These are mathematically distinct families. Do not mix them.
