Workflow actions currently use mutable release tags, so their code can change without a repository update. Pin all 37 external action references across the nine workflows on main to verified commit SHAs, with exact release-version comments for readable reviews and automated updates.

Preserve each reference's currently resolved version, including the existing setup-node v6.4.0 pin in Python CI. Resolve annotated tags to the underlying commit; the existing pnpm SHA was a tag object pointing at the same v4.3.0 release. Local reusable workflow references remain unchanged.

Enable pinDigests for Renovate's github-actions manager so it maintains these pins and pins newly added actions (Renovate documentation).

This is the independent action-pinning follow-up to #906, based on main. Its new Prettier workflow is still in that open PR and will be covered by the Renovate rule once merged.

Validation:

  • Resolved every original reference through GitHub's API and independently verified the release comment against the same commit SHA.
  • Parsed all nine workflow YAML files and verified that the only semantic changes are the 37 action references; triggers, permissions, inputs, commands, and local workflow calls are unchanged.
  • Validated renovate.json against Renovate's official JSON schema.
  • Prettier checks for all workflows and Renovate configuration, plus git diff --check, pass.

Summary by CodeRabbit

  • Chores
    • Pinned GitHub Actions used by build, test, documentation, deployment, publishing, and example workflows to immutable commit references.
    • Added version annotations to make pinned action versions easier to identify.
    • Configured dependency updates to preserve immutable GitHub Actions references automatically.
    • Workflow behavior, inputs, triggers, and permissions remain unchanged.

official actions/checkout persist-credentials default documentation

💡 Result:

The default value for the persist-credentials input in the actions/checkout GitHub Action is true [1][2][3]. When persist-credentials is set to true (the default), the action configures the GITHUB_TOKEN or SSH key with the local git configuration [1][2][4]. This persistence allows subsequent steps in your workflow to execute authenticated git commands [1][4]. The token is removed during the post-job cleanup process [1][2]. To disable this behavior, you must explicitly set persist-credentials to false in your workflow file [1][2]. While there have been community discussions and pull requests proposing to change this default to false to enhance security [5][6], as of September 2026, the official documentation and the action.yml configuration continue to list the default as true [3].

amannn/action-semantic-pull-request v6.1.1 required GITHUB_TOKEN permissions pull-requests read statuses write

💡 Result:

For amannn/action-semantic-pull-request version 6.1.1, the required GITHUB_TOKEN permissions depend on whether you are using the Work-In-Progress (WIP) feature [1][2]. 1. Standard Usage: If you are only validating the pull request title, pull-requests: read is sufficient [3]. This allows the action to fetch the pull request title via the GitHub API and determine if it adheres to your requirements [3]. 2. WIP Feature Usage: If you enable the wip feature (which keeps the PR status as "pending" while [WIP] is in the title), you must grant pull-requests: write permission [1][2]. Some users have reported that in certain workflow configurations, statuses: write may also be required to avoid "Resource not accessible by integration" errors when using the WIP feature [4][5]. While the official documentation primarily emphasizes pull-requests: write for this feature, statuses: write is a recognized fix for permission-related errors encountered during WIP status updates [4][5]. To configure this in your workflow file, you should explicitly define the permissions at the job level [1]: permissions: pull-requests: read # Required for title validation # statuses: write # Add this if you encounter errors using the WIP feature The action's main documentation recommends pull-requests: read for general use and pull-requests: write when using the WIP feature [1][2].
