      "summary": "Reviewed the ARM assembly implementation of `curve25519_x25519_byte`, which performs local X25519 scalar multiplication, modular inversion, and bytewise input/output packing entirely in-process. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious indicators in this file.",
