{
  "summary": "Reviewed this ARM assembly implementation of `bignum_invsqrt_p25519`, which computes an inverse square root modulo Curve25519's field prime and returns a Legendre/Jacobi symbol. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior; none were present in this file.",
