Creating and using a wheelhouse for offline Python installs

A wheelhouse is a pre-built directory of wheels created on a network-connected build machine and installed offline on a target machine. Pin a requirements file, run pip wheel, archive with tar, then install with --no-index --no-deps --force-reinstall.

Python: Store verifiable dependency description and build environment details as separate parts of a reproducible release contract

Store runtime dependencies in [project.dependencies] and build requirements in [build-system.requires] of pyproject.toml, then pin exact versions with sha256 hashes in a separate requirements file to create a byte-level verifiable release contract.
