      "summary": "Reviewed the x86-64 assembly implementation of SM2 modular inversion in `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/x86_att/sm2/bignum_inv_sm2.S`. It performs fixed arithmetic and stack/register management only; I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
