Start with suites/durableobject-scope/test.ts and the linked Cloudflare Integration Tests run, focusing on the nested direct call within one invocation. Reproduce the reported flakiness and determine the conditions under which isolation scopes differ; done means the test consistently passes without losing the intended isolation behavior.
