  "summary": "Reviewed the target file as a standalone ARMv8.4-a SHA3/Keccak-f1600 assembly implementation for four parallel states. I checked it for install-time hooks, subprocess or syscall execution, network or credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
