{
  "summary": "Reviewed `bignum_montifier.S`, an x86-64 assembly routine that computes a Montgomery-related constant and performs in-place bignum normalization/reduction. I checked for install-time hooks, subprocess launch, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/aarch64/src/rej_uniform_table.c`, which is a generated AArch64 lookup table for ML-KEM rejection sampling plus a compile-time empty translation unit fallback. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.",
