I checked for install hooks, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.\nReviewed the target x86-64 assembly file implementing SM2 mixed Jacobian point addition in Montgomery form. I checked for install-time hooks, subprocess or network/exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators.",
