      "summary": "Reviewed the ARM assembly implementation of `sha3_keccak4_f1600`, which appears to be a deterministic Keccak-f1600 permutation for SHA3 batch processing. I checked 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 in this file.",
