      "summary": "Reviewed this ARM assembly source, which defines three local read-only data tables and two simple functions that index into them and return a summed value. I checked for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators.",
