| # 1. The .gitlab-ci.yaml file exists and validates | |
| # 2. The PR submitter has write access to the target repository. | |

| # DO NOT MODIFY this workflow, unless you **REALLY** know what you are doing. | |
| # | |
| # This workflow bypasses some of the built-in protections of the | |
| # `pull_request_target` event by explicitly checking out the PR's **HEAD**. | |
| # Without being VERY CAREFUL, this could easily allow a malcious PR | |
| # contributor the chance to access secrets or a GITHUB_TOKEN with write scope!! | |
| # | |
| # The jobs in this workflow are designed to handle this safely -- but DO NOT | |
| # assume any alterations will also be safe. | |
| # | |
| # For general information, see: | |
