{
  "summary": "Reviewed the x86-64 assembly implementation of `sm2_montjadd`, which is a self-contained SM2 Montgomery-Jacobian point-addition routine built from arithmetic macros, register saves/restores, and conditional moves. I checked for install-time hooks, subprocess or control-flow to external payloads, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
