{
  "summary": "Reviewed the ARM assembly implementation of `secp256k1_jdouble_alt`, which performs deterministic Jacobian point-doubling and helper big-number reduction routines for secp256k1 field arithmetic. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file.",
