{
  "summary": "Reviewed the target assembly implementation of `edwards25519_scalarmulbase`, which is a handwritten x86-64 scalar-multiplication routine for Curve25519/Ed25519 with large constant tables and conditional-move arithmetic. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/packing, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
