GitHub refuses these runs at workflow-creation time: Error calling workflow ... The workflow is requesting '<perm>', but is only allowed '<none>'. A workflow_call job must grant a superset of the callee's declared permissions. This adds the canonical grant (actions: read, contents: read, security-events: write) that the healthy repos already carry.

📝 Summary

Summary by CodeRabbit

  • Security
    • Updated workflow permissions to support security analysis, secret scanning, and security alert reporting.
    • Standardised read access for actions and repository contents across automated workflows.
  • Chores
    • Improved the reliability and consistency of repository governance, mirroring, Rust CI, scorecard, and secret-scanning automation.

Walkthrough

The workflows now declare explicit job-level permissions for reusable workflow calls. The declarations add or retain read access for Actions and repository contents, and add security-events write access where required.

The workflow jobs now declare explicit permissions. Governance, mirror, and Rust CI grant actions: read, contents: read, and security-events: write. Scorecard adds actions: read. Secret scanning adds actions: read and security-events: write.

Three continuous-integration workflow files are not valid and cannot be loaded, so governance, mirroring, and Rust CI checks would stop running entirely on this branch. The indentation must be corrected before merging.

Align the three permissions blocks with uses.

The permissions key has six leading spaces, while the job key and uses key have four. This makes all three workflow files invalid YAML, so GitHub Actions cannot load them.

  • .github/workflows/governance.yml#L38-L41
  • .github/workflows/mirror.yml#L19-L22
  • .github/workflows/rust-ci.yml#L21-L24

Move each permissions key to the same indentation as uses.
