3/// An API failure with a message written for the caller.
4///
5/// The phone surface deliberately answers with fixed strings, because its
6/// errors would otherwise name profile homes and SSH hosts to a browser. Here
7/// the caller is the same user who owns the daemon, and the whole value of the
8/// API is knowing *why* a turn or an export failed, so the message is dynamic.
