Superforecaster pipeline — LHS sampling → polynomial chaos expansion (PCE) → Sobol’ sensitivity indices → Bayesian optimization.

Mirrors v26’s mc.superforecaster: cheaply explore the parameter box with Latin Hypercube Sampling, build a polynomial surrogate (PCE) for variance-based sensitivity analysis, then refine the optimum with the GP/EI optimizer from crate::bayesian.

The PCE uses probabilists’ Hermite polynomials (the orthogonal basis of the standard normal), so Sobol’ indices are analytic in the coefficients: S_i = Σ_{α: αᵢ>0} c_α² / Σ_α c_α².
