I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence logic, or other hidden execution behavior.",

      "summary": "This file implements the Keccak-1600 absorb, squeeze, and round-permutation logic plus CPU-specific dispatch to assembly or the local C fallback. I reviewed it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
