# audit: the python-audit sub-package cannot work, whatever it costs.
#
# The wheel is built by the HOST's python 3.13 and carries a cpython-313 ABI
# tag; Arch ships python 3.14. No destination makes it importable on the
# target -- the same reason python-brotli and python-libseccomp were dropped.
# Stage 2 builds it against the port's own python, where the tag matches.
#
# THE COST ARGUMENT IS NOT THE REASON, and that distinction is worth keeping.
# python-brotli was dropped when the repository held forty packages and
# `python` dragged libffi, mpdecimal and gdbm in behind it. Measured again at
# 131 packages, python costs three: the closure had filled in around it. So
# the cheap-versus-expensive reasoning that was right then is wrong now, and
# reusing it here would have been reasoning from a stale measurement.
#
# What has not changed is the ABI. That is why this one goes.
#
# build() still builds the wheel -- one function for every sub-package -- and
# the result is simply not packaged. package_python-audit() stays in the file,
# uncalled, like package_libquadmath() in gcc.
