```

## Dispatch Contract

The child thread must:

1. Sleep for 2 minutes after the formal start message.
2. Write `test-1-child-result.md`.
3. Send a callback to the parent thread using `send_message_to_thread`.
4. Report whether callback sending succeeded.

The parent thread must not inspect or poll the child thread after dispatch. If the parent wakes from the child callback, it may write `test-1-report.md`.
