Start with the Cloudflare Integration Tests job and the named test at suites/tracing/propagation/workerentrypoint-workerentrypoint-do-rpc/test.ts. Review the linked test run to identify the failure pattern, then reproduce the flaky trace propagation test. Done means the test passes reliably without intermittent failures.
