| # Push a release to the lean4-pr-releases repository, whenever someone pushes to a PR branch. | |
| # This needs to run with the `secrets.PR_RELEASES_TOKEN` token available, | |
| # but PR branches will generally come from forks, | |
| # so it is not possible to run this using the `pull_request` or `pull_request_target` workflows. | |
| # Instead we use `workflow_run`, which essentially allows us to escalate privileges | |
| # (but only runs the CI as described in the `master` branch, not in the PR branch). | |
| # The main specification/documentation for this workflow is at | |
| # https://leanprover-community.github.io/contribute/tags_and_branches.html | |
| # Keep that in sync! | |
