I checked for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior; none are present in this file.",

      "summary": "Reviewed the ARM assembly implementation of `bignum_sqr`, which performs local multi-precision squaring with register arithmetic, loads, stores, and a normal return path. I checked for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file.",
