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
    • Improved security workflow permissions to support reporting and processing security findings.
    • Limited reusable workflow access to the permissions required for repository content and security event handling.

Walkthrough

The pull request adds explicit job-level permissions to the governance and secret-scanner reusable workflow calls. Both jobs can read actions and contents, and can write security events.

Changes

Workflow permissions

Layer / File(s) Summary
Explicit job permissions
.github/workflows/governance.yml, .github/workflows/secret-scanner.yml
The governance and secret-scan jobs declare actions: read, contents: read, and security-events: write permissions at job level.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Bug fix

Merge Risk: 🔴 Critical · up to 17c03

The added permission settings are indented incorrectly in both workflow files, so neither the governance nor the secret-scanning workflow can be read or run. Automated policy checks and secret scanning would stop entirely until the indentation is corrected, so this must be fixed before merging.

Fix the indentation of both job-level permissions blocks.

jobs: is at column 1, each job key at column 3, and uses: is at column 5. In both workflows, permissions: is at column 7, so YAML parsing fails. Align permissions: with uses: and secrets:.
