      "summary": "Reviewed the AArch64 assembly implementation of `bignum_inv_p384`, which performs modular inversion for the P-384 field using divstep-style arithmetic and Montgomery reduction. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.",
