not_sandboxed(+User, +Application) is semidet[multifile, library(pengines)]

This hook is called to see whether the Pengine must be executed in a protected environment. It is only called after authentication_hook/3 has confirmed the authentity of the current user. If this hook succeeds, both loading the code and executing the query is executed without enforcing sandbox security. Typically, one should:

1. Provide a safe user authentication hook.
2. Enable HTTPS in the server or put it behind an HTTPS proxy and ensure that the network between the proxy and the pengine server can be trusted.
