{
  "summary": "Reviewed the x86-64 assembly implementation of `mlkem_basemul_k4`, which is a straight-line AVX2 polynomial multiplication routine for ML-KEM. I checked for install-time hooks, hidden subprocesses, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation/packing, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
