{
  "summary": "Reviewed the x86-64 assembly implementation of `sha3_keccak4_f1600`, which performs the Keccak-f1600 permutation over four parallel states using SIMD loads, bitwise operations, rotates, and stores. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, persistence, and other hidden subprocess behavior, and found no concrete malicious or supply-chain indicators in this target file.",
