{
  "summary": "Reviewed `mlkem_ntt.S`, a hand-written x86-64 AVX/AVX2 assembly implementation of ML-KEM's forward NTT that only performs register arithmetic, table reads from the provided `qdata` pointer, and in-place writes back to the input buffer. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behaviors.",
