Noticeable local file size change in modeling_acestep_v15_turbo.py after download: any idea what modifies it?

Hey everyone, Like many of you, I've been setting up ACE Step 1.5 locally. To get it working, you need to pull the model from the Hugging Face repository, which gets placed into the local ACE-Step-1.5/checkpoints directory. Everything is working fine, but I noticed something a bit unusual with the local model files and wanted to see if anyone knows the technical reason behind it. The Observation: At some point after the initial download, a specific Python file in the model directory gets modified.
