{
  "summary": "Reviewed the ARM assembly implementation of `curve25519_pxscalarmul`, which is a straight-line Curve25519 scalar-multiplication routine with constant-time arithmetic, stack/register setup, loop control, and a small special-case patch for the 2-torsion point. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload execution in this target file.",
