Resolved GitHub repositories used by the verified playground build, combining direct and indirect dependencies. This list does not describe internal module dependencies or native system libraries.
No additional GitHub package dependencies were recorded for this verified build.
Build record verified 2026-10-27.
These selected builds include this repository directly or indirectly. Each link to source identifies the revision that build uses.
These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.
Module: fordiff
H1: verified
Derivatives / callbacks: function values; finite differences or complex step
Numerical differentiation; the selected method controls callback requirements. 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.
