{
  "summary": "Reviewed the ARM64 P-256 Montgomery-Jacobian scalar multiplication implementation in this file. It is fixed-control-flow big-number arithmetic with local subroutine calls only, and I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload execution.",
