This adds an explicit
permissions:block to the tests workflow so the GitHub-issued token for runs oftests.ymlis granted only the scopes the job actually uses.The change is
permissions: contents: readat the top level. The workflow checks out the repo and runs its declared steps; there is nogit push, nogh release create, no comment-on-PR action, no API write.contents: readis therefore the minimum sufficient scope.Why bother for a workflow that looks innocuous: the worry is not what this workflow does today, it is what an action used inside it might be coerced into doing tomorrow if a third-party dependency in the action chain is compromised. The CVE-2025-30066 (tj-actions/changed-files, March 2025) incident is the canonical recent example. Without an explicit
permissions:block, the run inherits the repository-default token scope, which is permissive on many older repos.Aligns with GitHub's own token-hardening guidance and OpenSSF Scorecard (Token-Permissions). Standalone diff, no behavior change, YAML re-parses with
yaml.safe_load.
