 # This workflow acts as the final gate in the CI/CD pipeline for MaxText Docker images.
 # Triggered by:
 # 1. Airflow DAG completion (repository_dispatch):
-#    - Validates the result of the Airflow DAG (E2E tests).
-#    - Validates the result of the nightly build pipeline that produced the Docker images.
-#    - If both succeed, it promotes the Docker images by tagging the artifact with the latest tag.
+#    - Tags the tested Docker image with the result of the Airflow DAG (E2E tests):
+#      verified-e2e-<tag>, failed-e2e-<tag>, or unknown-e2e-<tag>.
+#    - If E2E passed on an image from the daily build that also passed CI (verified-ci-<tag>),
+#      it promotes the image (and its nightly counterpart) by tagging it with the latest tag.
 # 2. Manual workflow dispatch (workflow_dispatch):
-#    - Forcefully promotes the Docker images when Airflow E2E tests could not run (e.g. due to capacity).
