/// are written in C#, plugin authors will describe theirs in Lua, and the assistants are to be
/// offered as tools as well — each arrives differently, yet the registry validates and serves
/// them all the same way.<br/><br/>
/// A source is asked once while the registry is being built. Definitions do not change while the
/// app runs; a plugin that was loaded later needs the registry rebuilt, not the source re-read.
