{
  "summary": "Reviewed the x86-64 assembly implementation of `bignum_inv_p384`, which is a hand-written modular inversion routine for P-384 using stack-resident temporaries, arithmetic, and loop control only. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.",
