      "summary": "This file is an ARM assembly implementation of P-384 Montgomery squaring with an in-place final conditional reduction, using only integer arithmetic, loads, stores, and a return. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
