Review Summary

Reviewed the ARM assembly implementation and embedded read-only tables in `aws-lc/third_party/s2n-bignum/arm/curve25519/curve25519_x25519base_byte.S`. It appears to be straight X25519/Curve25519 field arithmetic with a loop branch and final `ret`, and I found no concrete indicators of install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence.
