{
  "summary": "Reviewed the ARM assembly implementation of `secp256k1_jadd`, which performs deterministic Jacobian point addition and field arithmetic for secp256k1. I found no concrete malicious or supply-chain indicators in this file: no install-time hooks, network or exfiltration logic, credential or environment access, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering behavior.\nReviewed an ARM assembly implementation of SM2 Montgomery-Jacobian point addition that is composed of field arithmetic macros, conditional selects, and stack-local temporaries. I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators in this file.",
