  "summary": "Reviewed this target x86-64 assembly implementation of P-256 Montgomery-Jacobian scalar multiplication, including its table setup, constant-time selection, arithmetic subroutines, and all visible control transfers. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, hidden downloads, dynamic code loading, obfuscation, persistence tampering, or other supply-chain compromise in this file.",
