      "summary": "Reviewed the x86-64 assembly implementation of P-521 Jacobian point addition, including the arithmetic macros, stack/register setup, and final conditional multiplexing of outputs. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence; the file is straight-line finite-field math and ABI handling.",
