{
  "summary": "Reviewed the assembly implementation in `edwards25519_scalarmuldouble_alt.S`, which is a hand-written x86-64 Edwards25519 double-scalar multiplication routine using constant-time table selection and stack-based finite-field arithmetic. I checked for install hooks, network or exfiltration paths, credential or environment access, dynamic code loading, obfuscation/packing, and persistence/tampering behavior, and found no concrete malicious or supply-chain indicators in this file.",
