{
  "summary": "Reviewed the target assembly implementation of `secp256k1_jdouble_alt`, which performs Jacobian point doubling for secp256k1 using fixed arithmetic macros and register/stack temporaries. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
