 ### Test Plan
 
-- Unit tests
-- Integration tests
-  - Previously auto-generated secret-based token that's used within the
-    configurable cleanup duration will continue to work.
-  - Previously auto-generated secret-based token that's used after the
-    configurable cleanup duration will be deleted.
-- E2E tests
-  - Secret-based tokens would not be auto-generated.
-  - Still able to explicitly request a secret-based token.
-  - The explicitly requested token would not be deleted.
+[X] I/we understand the owners of the involved components may require updates to
+existing tests to make this code solid enough prior to committing the changes necessary
+to implement this enhancement.
