Netlify migrated the docs site to the Ubuntu 24.04 (Noble) build image, which installs toolchains with mise. mise verifies GitHub artifact attestations on the python-build-standalone tarballs it downloads, and CPython 3.8.20 predates attestation coverage, so the pinned runtime cannot be installed: mise ERROR Failed to install core:python@3.8: No GitHub artifact attestations found for python@3.8.20 Every Netlify deploy since 2026-09-25 07:27 UTC has failed, including the production builds for the merges of open-policy-agent#1430, open-policy-agent#1427 and open-policy-agent#1428. The last successful publish of conftest.dev was 2026-09-19, so the site is missing all three. Bump runtime.txt to 3.12 and bring the docs toolchain forward to match, since mkdocs-material 4.6.3 (2020) does not install under Python 3.12. No mkdocs.yml changes are needed; the codehilite extension still works under Markdown 3.x. Signed-off-by: boranx <boran.seref@gmail.com>
