{
  "summary": "Reviewed the ARM assembly implementation of `bignum_inv_p384`, which performs constant-time modular inversion and Montgomery-style reduction using only local stack temporaries and register arithmetic. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden control transfers, and found no concrete malicious or supply-chain indicators in this file.",
