      "summary": "Reviewed the x86-64 assembly routine `bignum_mod_p384_6`, which performs a fixed modular reduction for P-384 field elements and only contains deterministic register arithmetic and ABI handling. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",

      "summary": "Reviewed `aws-lc/third_party/s2n-bignum/x86_att/p384/bignum_mod_p384_alt.S`, an x86-64 assembly routine that reduces a multi-limb integer modulo the P-384 field prime and writes the reduced 6-word result. I checked for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
