{
  "summary": "Reviewed the x86-64 assembly implementation of `edwards25519_scalarmuldouble`, including the arithmetic macros, local helper routines, and the embedded precomputed basepoint table. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential or environment harvesting, dynamic code loading, obfuscation/decoding pipelines, persistence mechanisms, or hidden subprocess execution.",
