{
  "summary": "Reviewed the x86-64 assembly implementation of `edwards25519_decode_alt` and its local field-arithmetic helpers. It appears to perform constant-time Curve25519/Edwards25519 point decoding and modular multiplication/squaring with explicit input validation; I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.",
