{
  "summary": "Reviewed the ARM64 assembly implementation of `curve25519_x25519`, which performs X25519 scalar multiplication and stack/register save/restore in a single exported routine. I checked for install hooks, syscalls, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation/decoding, persistence tampering, and other hidden payload execution; none were present in this file.",
