## Title

    [llama.cpp convert_hf_to_gguf.py] "Missing or incomplete model files" / "Mismatch between weight map and model parts" - partial safetensors download

## Body

    Cause (Documented platform behavior): Converter compares tensor names in index weight_map vs tensors found in parts.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - Mismatch between weight map and model parts for tensor names:
