      "summary": "Reviewed the full ARM assembly implementation of `curve25519_pxscalarmul`, including its helper macros and the exported scalar-multiplication routine. It only performs constant-time Curve25519 field arithmetic and stack/register management; I found no install hooks, subprocess or network activity, credential access, dynamic code loading, obfuscation, or persistence behavior.",
