{
  "summary": "Reviewed the ARM NEON assembly implementation of X25519 scalar multiplication in `crypto/curve25519/asm/x25519-asm-arm.S`. It contains only finite-field arithmetic, loop control, clamping, copying, and stack/register save/restore; I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden payload execution.",
