NameError: `chain_prompt` is not defined in FullyDeterminer.analyze_trace_with_deepseek

[BACMiao]

Summary

In LLM-assisted_Validation/ds_llm_fully_determine_mul.py, the method FullyDeterminer.analyze_trace_with_deepseek references a local variable chain_prompt that is never defined anywhere in the file. As a result the final, chain-level verdict step raises NameError, which is caught by the surrounding try/except and silently replaced with a hard-coded is_vulnerability: False. So the per-trace propagation verdict produced by stage-3 is never actually computed by the model.

Question

Could you confirm whether a chain_prompt = ... assignment was meant to be included here? If so, sharing that snippet would let us reproduce the intended stage-3 verdicts. Thanks for releasing the code!
