  "summary": "Reviewed the target file as a handwritten x86-64 assembly implementation of P-521 Jacobian point doubling plus helper field-arithmetic macros. I checked it for install-time hooks, hidden subprocess or network/exfiltration behavior, credential or environment access, dynamic code loading, obfuscation/packing, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
