+    The logic for applying enhanced pipelines for Ceilometer+Gnocchi has been corrected.
+    When no custom content is provided, the role now populates
+    sinks and transformation overrides defined in pipeline.yaml with default content,
+    rather than layering them on top of user-defined content.
