# whether a file's owner may execute it, from the mode `find` prints as
# `%M`, `-rwxr-xr-x`: the fourth character is `x`, or `s` when the setuid
# bit is set as well. This is the mode bit nix's NAR dumper reads
# (`S_IXUSR`), not an access check, so a file the owner may not execute is
# not executable whoever weighs it.
