In this tutorial, you learned what Rules are, how to create one using a CEL-based expression, and how to preview it against an existing Run to verify it behaves as expected.
You also generated a Report to review the Rule's evaluations, inspect the Annotations it triggered, and assess system behavior during a Run.
