      "summary": "This AArch64 assembly file implements `curve25519_x25519base_byte_alt`, a constant-time X25519/Curve25519 scalar-multiplication routine with large precomputed point tables and modular-arithmetic helpers. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
