{
  "summary": "Reviewed the x86-64 assembly implementation of `p521_jdouble`, which performs P-521 Jacobian point doubling entirely through inlined field-arithmetic macros and register/stack operations. I checked for install-time hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators.",
