Start by tracing infer/modules/vc/modules.py:185 into infer/modules/vc/pipeline.py:235 and the index.search call at pipeline.py:410, then reproduce the reported inference failure. Compare the FAISS dimension assertion with the later Gradio NoneType error; done means the original failure is diagnosed and inference has a verified, user-visible outcome.
