      "summary": "Reviewed the ARM assembly implementation of `curve25519_x25519base_byte`, which performs Curve25519/X25519 base-point scalar multiplication and writes the result to the output buffer. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise signals in this file.",
