      "summary": "I reviewed the full ARM assembly implementation of X25519 in `aws-lc/third_party/s2n-bignum/arm/curve25519/curve25519_x25519_byte_alt.S`, including input byte parsing, the Montgomery ladder, the inline modular inverse, and final byte serialization. I found no concrete indicators of install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.",
