docs_host	readthedocs / github-pages (readthedocs)	Documentation host (see below).
extension	none / mypyc (none)	Compiled-extension strategy (see below).

extension

• none (default) — pure-Python. Build backend is Hatchling; release builds a universal wheel + sdist with uv build and publishes via trusted publishing (with Sigstore + provenance).

• mypyc — compiled wheels. Build backend is setuptools, setup.py compiles core.py with mypyc, a tests_compiled nox session runs against the C extension, and the release workflow uses cibuildwheel to build per-platform wheels.

docs_host

The docs are built with Sphinx either way; this chooses where they’re served:

• readthedocs — ships a .readthedocs.yml; import the repo on Read the Docs.

• github-pages — ships a docs.yml workflow that builds and deploys to GitHub Pages.
