- Use data-code-execution as the streaming source of truth and hide
duplicate code-interpreter tool parts (including tool-execute_tool
wrappers).
- Ensure wrapped execute_tool code-interpreter outputs still render
correctly after refetch.
- Gate code-interpreter server behavior by enablement state and keep
assistant messages full-width to avoid streaming vs completed width
shifts.
