  "summary": "Reviewed the x86-64 assembly decoder for compressed edwards25519 points in `aws-lc/third_party/s2n-bignum/x86_att/curve25519/edwards25519_decode.S`. It is a self-contained finite-field/curve arithmetic routine with internal helper calls and stack/register management; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.",
