{
  "summary": "Reviewed this x86-64 assembly source for P-256 Montgomery-Jacobian scalar multiplication and checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution. It appears to be a self-contained constant-time cryptographic routine with local arithmetic helper calls only, and I found no concrete malicious or supply-chain indicators in the target file.",
