{
  "summary": "Reviewed this assembly implementation of `p256_montjdouble`, which performs P-256 point doubling in Montgomery-Jacobian coordinates using local register/stack arithmetic only. I checked for install hooks, subprocess launch, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in the target file.",
