{
  "summary": "Reviewed this ARM assembly implementation of `curve25519_x25519base_byte_alt`, which performs X25519 scalar multiplication over Curve25519 using inlined finite-field arithmetic and precomputed constants. I checked for install hooks, subprocesses, network or exfiltration paths, credential/secret access, dynamic code loading, obfuscation/deobfuscation, persistence, and other hidden payload behavior; none were present in this file.",
