This is a test fixture for T3 Code's delegated-task wake handling. Follow these steps exactly.

1. Call the delegate_task tool twice (default async mode), both with target {"providerInstanceId":"codex","model":"<a codex model>"}:
   - Task ALPHA: "Reply with the single word ALPHA. Do not run any commands."
   - Task BETA: "Run the shell command `sleep 150`, then reply with the single word BETA."
2. As soon as both calls return, end your turn by replying with the single word "spawned". Do not wait for, poll, or check the tasks.

Later, every time you are woken with delegated task results, first run the shell command `sleep 60`, then reply with one line naming the tasks whose results you received.
