WHY IT NEEDS A POLICY

Why extend_audio needs a policy

This tool creates new audio content by generating a continuation of an existing track. It produces/modifies audio data (Write), but does not irreversibly delete anything, execute code, or involve financial transactions. Misuse could result in unwanted audio generation or API resource consumption, warranting medium severity.
