sciter ships with their own TIscript engine, which it's a small subset of JavaScript mostly for interop with the application and manipulation of the sciter HTML renderer. Seems the original thread is a javascript interpreter for sandboxing and analysing JavaScript in-engine. UI process doesn't run as system either since there is no gui on that space. you'll find the sciter code in the user processes (tray and app).
