Topics: codata, fortran, fortran-package-manager, nist, physical-constants, physics

Classification scope and review notes

CODATA physical constants. The checked main imports the explicit 2022 edition, computes the energy of a 500 nm photon in joules and electron volts, and compares it with independent decimal reference values. The source modules are pre-generated; no network request or Python generation is needed to use them. No source edits. This is a check of three constants and one calculation, not revalidation of the complete CODATA tables or uncertainty propagation.

Package dependencies

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.

Reviewed procedures

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