{
  "summary": "Reviewed the ARM64 assembly implementation of `p256_montjdouble`, which is a straight-line NIST P-256 Montgomery-Jacobian point-doubling routine with stack frame setup/teardown and arithmetic only. I checked for install-time hooks, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
