{
  "summary": "Reviewed the generated x86 SSSE3 GHASH assembly in this target file. It contains only fixed crypto routines and constant data, with no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms; no concrete malicious or supply-chain indicators were found.\nReviewed this x86-64 assembly implementation of the ML-DSA forward NTT. It consists of deterministic AVX2 butterfly/shuffle arithmetic on caller-provided buffers and precomputed twiddle factors, with no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.\nReviewed the hand-written x86-64 assembly implementing P-384 Montgomery conversion in this file. It performs only fixed arithmetic on the input/output buffers with normal ABI save/restore and contains no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed aws-lc/crypto/fipsmodule/bn/bytes.c, which implements BIGNUM byte/word conversion helpers and length/bounds checks. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess execution; no concrete malicious or supply-chain indicators were found.",
