{
  "summary": "Reviewed the x86-64 assembly implementation of Curve25519/X25519 scalar multiplication and field inversion in this file. It is deterministic arithmetic on registers and stack memory only; I found no concrete malicious or supply-chain indicators such as install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence.",
