+# Workflow Name Synchronization Test
+
+## Implementation Summary
+
+✅ **COMPLETED**: Header component workflow name synchronization with parent state
+
+### Changes Made:
+
+1. **page.tsx**: Added `handleWorkflowNameChange` handler
+   - Receives new workflow name from Header component
+   - Updates `currentWorkflowName` state 
+   - Avoids duplicate localStorage saves (Header already handles it)
+
+2. **Header component integration**:
+   - Added `onWorkflowNameChange={handleWorkflowNameChange}` prop
+   - Header calls this callback when user edits workflow name
+   - Maintains two-way data binding between Header and parent
+
+### How it works:
+
+1. **Initial load**: `currentWorkflowName` state initialized from localStorage
+2. **Prop to Header**: `workflowName={currentWorkflowName}` passed to Header
+3. **User edits in Header**: Header calls `onWorkflowNameChange(newName)`
+4. **State update**: `handleWorkflowNameChange` updates parent state 
+5. **Re-render**: Header receives updated `workflowName` prop
+
+### Code Flow:
+
+```
+User edits in Header → Header.handleSaveClick() →
