_⚠️ Potential issue_ | _🟠 Major_

**Update code example to reflect the bug fix mentioned in line 13.**

The implementation summary (line 13) states that the default parameter binding bug was fixed by changing `stream=sys.stderr` to `stream=None` with runtime resolution, but this code example still shows the old buggy pattern. Update the code to match the actual fix.

In `@issues/subtask-6-streaming.md` around lines 62 - 63, The example for _emit
still uses the old default parameter stream=sys.stderr; update the function
signature to use stream=None and add runtime resolution inside _emit (e.g., set
stream = sys.stderr if stream is None) so the default binding bug is fixed;
locate the _emit function and change its parameter and body to resolve the
stream at call time rather than at definition time.
