+  # IMPORTANT! This workflow is triggered by the `pull_request_target` event

+  # For this reason we only NEVER checkout the code from the pull request

+  # By default the checkout will be:
+  #   - GITHUB_SHA: Last commit on the PR base branch
+  #   - GITHUB_REF: PR base branch

+  # ...unlike a typical PR where:
