I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior and found no concrete malicious or supply-chain indicators in this file.",

It appears to be a straight polynomial-multiplication routine with stack save/restore and no concrete malicious or supply-chain indicators in the target file.",
