{
  "summary": "Reviewed the target ARM assembly implementation of `secp256k1_jdouble`, which is a pure elliptic-curve point-doubling routine with local arithmetic macros and stack/register management only. I checked for install hooks, subprocess spawning, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
