Enum SolverConfig 

pub enum SolverConfig {
    LevenbergMarquardt(LmConfig),
    PoissonKL(PoissonConfig),
    Auto,
}

Solver-specific configuration.

Carries the full solver config inside each variant, making invalid combinations unrepresentable.

Variants

LevenbergMarquardt(LmConfig)

Levenberg-Marquardt chi-squared minimizer (transmission path).

PoissonKL(PoissonConfig)

Poisson-KL counts-domain fitter.

For counts inputs this dispatches to the joint-Poisson profile- binomial-deviance path (joint_poisson_fit), validated against synthetic counts benchmarks and locked by a real-VENUS counts regression test on the committed aggregated-Hf fixture. Uses an explicit c = Q_s/Q_ob from CountsBackgroundConfig::c and reports D/(n − k) as the primary GOF. Stage-1 damped Fisher + optional Nelder-Mead polish (see nereids_fitting::joint_poisson::JointPoissonFitConfig).

For transmission inputs this dispatches to Poisson NLL on the transmission values directly (legacy path, unchanged). The payload PoissonConfig carries max_iter common to both dispatches.

Auto

Automatic: Counts → PoissonKL (counts-domain joint-Poisson), Transmission → LM.
