+
+          The weekly Google Colab execution check has failed. This indicates that one or more notebooks failed to execute properly in the Colab environment.
+
+          ## Details
+

+          **Commit:** ${{ github.sha }}
+
+          ## Execution Reports
+
+          Detailed execution reports have been uploaded as artifacts to this workflow run. Please check the following:
+
+          1. Download the `execution-reports` artifact from the workflow run
+          2. Review the failed notebook execution logs
+          3. Fix any execution issues in the notebooks
+          4. Test locally or in Colab before merging
+
+          ## Next Steps
+
+          1. Investigate the failure by reviewing the execution reports
+          2. Fix the identified issues
+          3. Test the fixes
