// trusted parent (main) process.
//
// Resolve() expands an id from the in-tree model table (see
// SpeechRecognitionModelMapping) to its concrete ModelHub artifact; it throws
// for any other id. This is what keeps the (less trusted) utility process from
// ever naming a model/revision/filename itself.
//
// AuthorizeDownload() skips the prompt when the model is already installed,
// honors the testing prefs, and otherwise shows the model-download permission
// doorhanger, allowing the download only on a real user Allow. Content can
// only ask; it never authorizes a download.
