{
  "summary": "Reviewed the target assembly file, which is a pure SM2 Montgomery-Jacobian point-addition routine built from field arithmetic macros, register saves/restores, and conditional output multiplexing. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators.\nReviewed the AArch64 assembly implementation of the ML-KEM forward NTT in `aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/aarch64/src/ntt.S`. It is a straight-line arithmetic kernel with stack save/restore and table-driven loads/stores only; I found no concrete signs of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
