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

Module: io_fortran_lib

N1

N1: verified

Derivatives / callbacks: not applicable

Numeric array file I/O; conversion and formatting capabilities are not mathematical solvers. Dedicated N1 consumer checks eight real64 matrix files across four shapes and two delimiters. Independent native Fortran parsing checks rows, delimiter counts and values, then library round trips and a hand-written CSV test the reader independently. Missing-file status/message and cleanup are checked. Headers, locale options, complex/integer arrays, other ranks, nonfinite values and formatting modes beyond exponential output are not verified.
