I checked for install-time hooks, network or exfiltration behavior, secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed the AArch64 ML-KEM inverse NTT assembly in `aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/aarch64/src/intt.S`; it is an auto-derived arithmetic routine that loads twiddle tables, transforms a polynomial buffer in place, and stores results back.
