      "summary": "Reviewed this ARM assembly implementation of `curve25519_x25519_alt`, which performs X25519 scalar multiplication plus an inline modular inverse and final field reduction. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this target file.",
