{
  "summary": "Reviewed the target x86-64 assembly implementation of modular square root and helper multiply/square routines for Curve25519 field arithmetic. I checked for install hooks, hidden subprocesses, network or credential access, dynamic code loading, obfuscation/deobfuscation, and persistence behavior, and found no concrete supply-chain or malicious indicators in this file.",
