The filename follows a structured hierarchy: speaker_idchapter_id-recording_id-version-quality .

If a system running v009 exhibits instability, engineers may downgrade to v008 . However, the hifi flag might be lost because v008 lacked a high-fidelity codec patch. This is why v009-hifi should be considered an atomic unit.
