 # Workflow derived from https://github.com/posit-dev/setup-air/tree/main/examples
 
 on:
-  # Using `pull_request_target` over `pull_request` for elevated `GITHUB_TOKEN`
-  # privileges, otherwise we can't set `pull-requests: write` when the pull
-  # request comes from a fork, which is our main use case (external contributors).
-  #
-  # `pull_request_target` runs in the context of the target branch (`main`, usually),
-  # rather than in the context of the pull request like `pull_request` does. Due
-  # to this, we must explicitly checkout `ref: ${{ github.event.pull_request.head.sha }}`.
-  # This is typically frowned upon by GitHub, as it exposes you to potentially running
-  # untrusted code in a context where you have elevated privileges, but they explicitly
-  # call out the use case of reformatting and committing back / commenting on the PR
-  # as a situation that should be safe (because we aren't actually running the untrusted
-  # code, we are just treating it as passive data).

-  pull_request_target:
+  # CI-VERIFY / DRY-RUN ONLY -- DO NOT MERGE. The real workflow uses
+  # `pull_request_target` (elevated token for fork PRs). But pull_request_target
+  # runs the workflow file from the repo's DEFAULT branch (main), so a modified
+  # format-suggest cannot be tested via a PR without touching main. To exercise
+  # the style + reviewdog logic end-to-end, this middle branch switches the
+  # trigger to `pull_request` (which uses the PR's own workflow file) and scopes
+  # it to PRs whose base is this middle branch -- i.e. only the outermost test PR
+  # triggers it, so this middle PR itself runs no checks.
