+/// The settings of a request carry the ID of the configured provider, see
+/// IProvider.CreateSettingsProvider. Through it, what the provider's own model list reported, such as
+/// the context window of a self-hosted model, reaches everything which asks the settings about the
+/// model: the tools offered in the request, and how images are passed on. Before the ID came along,
+/// the request knew the model only by the rules, while the provider dialog showed what the machine
+/// reported.<br/><br/>
+/// What a provider reported lands in the store the app shares, so these tests must not run next to
+/// anything else touching it.
