| # pull_request_target, not pull_request: a workflow Dependabot triggers gets a | |
| # read-only token, and approving and merging needs a writable one. | |
| # | |
| # That trigger runs with the base branch's secrets, which is only safe as long | |
| # as nothing here ever runs code from the pull request. Nothing does — there is | |
| # deliberately no checkout step, and every step below talks to the GitHub API | |
| # about the pull request rather than executing anything from it. Adding a | |
| # checkout, a build, or any step that reads a file from the head branch would | |
| # hand a dependency update write access to this repository, so do not. | |
