Appendix E. Numerical methods and additional results🔗

This appendix describes the numerical procedures behind Section 8. It records how parameters are drawn, how integrals and function-space inputs are discretized, and how the reported errors are measured. The figures and result tables are in Section 8.

1. E.1 Reproduction and error measurement
2. E.2 Gaussian directions and coefficient measures
3. E.3 Dirichlet layer and transform verification
