{
  "summary": "Reviewed this ARM assembly implementation of `curve25519_ladderstep`, which performs Curve25519 Montgomery ladder arithmetic with register moves, conditional swaps, and finite-field multiply/square/reduction macros. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other payload-like behavior in this file.",
