Tag refs (actions/checkout@v4, actions/setup-python@v5) are mutable — a retagged or compromised action would execute in CI. Pin both to the immutable commit SHA the major tag currently resolves to, with the tag kept as a trailing comment for readability and Dependabot updates. Also drops `security-events: write` from the workflow permissions block: no job uploads SARIF (bandit runs informational-only to stdout), so the grant was unused. Permissions are now the minimal `contents: read`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
