      "summary": "Reviewed the ARM64 assembly implementation of `p256_montjadd`, which performs P-256 Montgomery-Jacobian point addition with arithmetic, conditional reduction, and register/spill management only. I checked for install-time hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, persistence, and crypto-mining indicators, and found none.",
