{
  "summary": "Reviewed the x86-64 assembly implementation of P-256 scalar multiplication and found only constant-time elliptic-curve arithmetic and ABI glue. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
