+**Phase 10 — Widget Config Live Preview Sync & Type Switch Fix:**
+- [x] Fix: `DashboardWithConfig` did not pass `onFieldChange` to `WidgetConfigPanel`, preventing live preview of widget config changes
+- [x] Add internal `liveSchema` state to `DashboardWithConfig` for real-time widget preview during editing
+- [x] Add `configVersion` counter to stabilize `selectedWidgetConfig` and prevent `useConfigDraft` draft reset loops
+- [x] Fix: `scatter` chart type was not handled in `DashboardRenderer` and `DashboardGridLayout` — switching to scatter caused errors
+- [x] Add `scatter` to chart type conditions in both `DashboardRenderer.getComponentSchema()` and `DashboardGridLayout.getComponentSchema()`
+- [x] Add 3 new Vitest tests: scatter chart data extraction, scatter with object-chart provider, DashboardWithConfig live preview support
