The CPU-only Fortran target is configured upstream with FFTW enabled, MPICH, input checks, and no C/C++/Python API, GPU, compression or OpenMP support. Its complete generated configuration header and source selection are checksum-locked. The checked main initializes exactly one MPI process with self/shared-memory UCX transports, transforms an 8-by-8 complex impulse, independently checks that every forward coefficient equals one, then verifies inverse reconstruction after normalization. J1 covers the multidimensional Fourier transform. Multiple processes, distributed performance and other FFT executors are not verified by this example. Local exports require compatible MPICH and FFTW development libraries and locally appropriate include/link flags. GPL-3.0-or-later notices are retained.

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.
