Start with setup_env.py and utils/convert-hf-to-gguf-bitnet.py, then inspect logs/convert_to_tl.log and the contents expected under models/BitNet-b1.58-2B-4T. Determine why the setup command reaches conversion without config.json, and verify that the documented setup flow completes successfully for the reported model directory.
