# Native Dialog Workflows Blacksite routes native file, folder, Save As, and unsaved-change confirmation dialogs through the shared `NativeDialogBroker`. A native dialog may remain open without blocking Bevy's window event loop or editor rendering. ## Workflow Contract - One native dialog can be active at a time. Direct controls are disabled while pending; other concurrent requests report that a dialog is already open. - Native work returns only selected paths or a confirmation result. Scene, asset, project, history, registry, and collaborative-file mutations run later on the Bevy main thread. - Cancel is non-mutating and produces workflow-specific status. - Entity-based operations capture the initiating entity and reject stale results. Composition additions validate against the current composition so intervening edits are not overwritten. - Collaborative Save As performs the same revision and destination checks after selection. - Close or project switch never treats an opened Save As picker as a completed save. When a save remains pending, the transition pauses and can be retried after saving. ## Covered Surfaces The broker owns scene Open/Save As, import/export, prefab creation and relinking, recovery copies, subscene selection, collaborative conflict copies, Project Browser folder selection, and dirty-scene confirmations. New workflows must use the broker instead of calling `rfd` from an egui/Bevy system. See [ADR 0038](../adr/0038-non-blocking-native-dialog-broker.md). Live native-Wayland acceptance is recorded in the [native-dialog responsiveness evaluation](evaluations/native-dialog-responsiveness/).
