  "summary": "Reviewed the x86-64 assembly implementation of Curve25519/X25519 scalar multiplication and its inlined modular inversion path in this target file. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation/packing, or persistence/environment tampering; the file is limited to arithmetic, table lookup, and constant-time field operations.",
