| # ideally, this would just be "uses: ./checkout", but that's a chicken-and-egg that results in "Error: Can't find 'action.yml', 'action.yaml' or 'Dockerfile' under '/home/runner/work/actions/actions/checkout'. Did you forget to run actions/checkout before running your local action?" | |
| # the second-best would be "uses: tianon/actions/checkout@${{ github.sha }}" but that's *also* invalid because we don't get the "github" context here so we can't self-reference properly 🙃 | |
