      "summary": "Reviewed the x86-64 assembly implementation of P-256 Montgomery-Jacobian scalar multiplication in `aws-lc/third_party/s2n-bignum/x86_att/p256/p256_montjscalarmul.S`. It contains only constant-time field arithmetic and ABI glue; I found no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators.",
