| 1 | # Consolidated Security Scanning |
| 2 | # |
| 3 | # This workflow combines all security scanners into a single pipeline: |
| 4 | # - Bandit: Python SAST scanning for security issues in source code. |
| 5 | # - zizmor: Focuses on GitHub Actions-specific supply-chain risks such as |
| 6 | # template injection and dangerous triggers. |
| 7 | # |
| 8 | # All jobs run in parallel and upload SARIF results to GitHub Code Scanning. |
