- Pin actions/checkout, astral-sh/setup-uv, and pypa/gh-action-pypi-publish to full commit SHAs to prevent supply-chain attacks via tag mutation. The pypa publish action is highest-risk as it runs with id-token:write. - Add explicit `permissions: contents: read` to ci.yml jobs (test and docs) so GITHUB_TOKEN is scoped to the minimum needed; previously inherited the repo default which may include write permissions. - Add `contents: read` to release.yml publish job permissions block for the same reason (was implicitly none, which works for public repos but is misleading; explicit is clearer and safer). https://claude.ai/code/session_014iLSLtTwJkVR7B9PYqwJFA

repo default which may include write permissions.
