+# The test gate. Deploy waits for this workflow by name (`.gitea/workflows/deploy.yml`
+# triggers on `workflow_run: [Test]`), so renaming it here without renaming it there
+# would leave `main` publishing without a suite. `tests/integration/test_deploy_workflows.py`
+# asserts both halves of that link, and that the commands below are still the ones
+# configured in `work_item/.work-item.yml`.
