{
  "summary": "Reviewed the ARM64 assembly implementation of `p521_jadd_alt`, which performs P-521 Jacobian point addition and finite-field reduction using in-register arithmetic and stack temporaries. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden control transfers, and found no concrete malicious or supply-chain indicators in this target file.",
