setup.py

"""
BUG-14 fix: SHA baking is done inside setup.py itself via setuptools cmdclass
hooks. The logic intentionally lives here (not in a separate module file) so
that pip's isolated PEP-517 build environment can always find it — external
module imports at setup.py level are unreliable in isolated builds.
