| # This workflow runs as soon as the workflow from `code-coverage.yml` has | |
| # successfully finished. It downloads the created artifact and runs the | |
| # Codecov uploader. This workflow uses the `workflow_run` trigger. This | |
| # means that it will always be run from the master branch, meaning that | |
| # the contents of this file will always be taken from the master branch, | |
| # even if a PR changes it. Since this approach disallows several attacks | |
| # from malicious PR authors, such workflows have access to the secrets | |
| # stored on GitHub. For details on the `workflow_run` trigger and this | |
| # security measures, see | |
