I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior; the code is confined to arithmetic, temporary buffer management, and memory cleansing.",
