  "summary": "Reviewed `curve25519_x25519base.S`, which is a large hand-written x86-64 assembly implementation of Curve25519/X25519 scalar multiplication with embedded precomputed constants and ordinary prologue/epilogue flow. I checked for install hooks, network or exfiltration, credential/secret access, dynamic code loading, obfuscation/packing, persistence tampering, and hidden subprocess execution; no concrete malicious or supply-chain indicators were found in this target file.",
