      "summary": "Reviewed the ARM assembly implementation of `curve25519_x25519base_alt`, which performs X25519 scalar multiplication using fixed precomputed tables and inline big-number arithmetic. I checked for install-time hooks, subprocess spawning, network or exfiltration paths, credential/secret access, dynamic code loading, obfuscation, persistence, and crypto-mining behavior, and found no concrete malicious or supply-chain indicators in this file.",
