Description

• Adds GitHub's workflow dependency lockfile (.github/workflows/actions.lock). It records the commit behind every action the workflows use, and GitHub checks it at run time, so a moved tag or branch can't change what runs.
• That includes docker-publish.yml, where docker/login-action@v3 receives DOCKERHUB_TOKEN and docker/build-push-action@v5 pushes the image, and python-publish.yml, where pypa/gh-action-pypi-publish@release/v1 (a branch) publishes chainbench to PyPI with id-token: write.
• Generated with gh actions-lock and checked with gh actions-lock --verify (all 3 workflows valid, 12 actions plus 1 pulled in by the PyPI action).
• Action refs narrowed to exact releases, for example actions/checkout@v4.4.0 and docker/login-action@v3.7.0. pypa/gh-action-pypi-publish@release/v1 stays on its branch, locked on today's commit (v1.14.3). Only uses: lines change.
• Not covered by a lockfile: the container the PyPI action builds at run time.

The change pins workflow actions to exact commits and is a net improvement. The PyPI publish step still pulls a container image through a mutable tag, which the new lockfile cannot lock. This is a known, bounded gap that the owner should decide on, and it is not a regression from this change.

Full details: Title check

Explanation

The title names the main change: adding a GitHub Actions workflow dependency lockfile (actions.lock). The changeset adds the lockfile and narrows action refs to exact releases, so the title matches the primary change. It is short and specific.

Full details: Description check

Explanation

The description follows the template's two sections, Description and Issues Resolved. It explains what the lockfile does, which workflows it covers, how it was generated and verified, the action ref changes, and a known gap (the PyPI action's run-time container). Issues Resolved states 'None' with a reason, which satisfies the template.

Pin the PyPI publish image to a reference that does not move.

The publish step runs pypa/gh-action-pypi-publish@release/v1 with id-token: write. The lockfile pins the action commit. The generated Docker action does not use that commit's image. Its image is set from github.action_ref, which is release/v1. The upstream script then selects docker://ghcr.io/pypa/gh-action-pypi-publish:release-v1. The release-v1 tag is mutable. It can point to a new image while the locked action code stays the same. The container can then run different upload code with the OIDC token.

Choose a publish reference that selects an image that does not change. Confirm that the chosen tag exists in the registry before you pin it. Regenerate actions.lock after the change. A commit SHA as the ref also becomes the image tag, so confirm a matching image exists before you pin to a SHA.

Update the pypa/gh-action-pypi-publish reference to select a verified, non-moving container image tag; confirm the tag exists in the registry before using it, since pinning the action to a commit SHA alone does not pin the image. Regenerate actions.lock after updating the publish action reference.
