Research direction

Read stable_audio_tools/models/diffusion.py, especially DiTWrapper initialization and the no_grad parameter-scaling block. Trace where the model is loaded and used to establish why the 0.5 factor is applied; done means the rationale and expected behavior are documented or the issue is narrowed to a concrete change.

Written by the indexing model from the issue text.
