These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.

Module: ADdnSVM_m

H1: verified

Derivatives / callbacks: operator-overloaded forward automatic differentiation

Derivatives carried by automatic-differentiation types; not a finite-difference solver. The checked H1 driver uses exp(x)*sin(x) at four shared points with analytic references and explicit tolerances; only the recorded scalar configuration is verified.
