+/// Checks that the app reads every outcome which the runtime sends after a share request.
+/// </summary>
+/// <remarks>
+/// ShareFileResponse in runtime/src/share_sheet.rs names the outcome in snake case. A name which the
+/// app does not know would not fail anywhere: the enum converter falls back to the first member, and
+/// a share sheet which did not respond would go unnoticed again. The options mirror what RustService
+/// deserializes with.
