Reset history when the workflow changes.
undoStack and redoStack survive a workflow switch. If a user switches from workflow A to custom workflow B and presses undo, the code restores A into B. The autosave effect then persists A’s graph into B.
Clear both stacks in handleSelectWorkflow before loading the new graph.

React Flow 11.11.4 ReactFlow onNodeDragStart onNodeDragStop callback documentation
💡 Result:
In React Flow 11.11.4, the onNodeDragStart and onNodeDragStop props are callback functions used to listen to the lifecycle events of a node being dragged [1][2][3]. These callbacks utilize the OnNodeDrag type, which provides access to the interaction event and the nodes involved [4][5]. Type Signature: The callback signature is defined as: (event: MouseEvent | TouchEvent, node: Node, nodes: Node[]) => void [4][5] Parameters: 1. event: The original DOM event (MouseEvent or TouchEvent) that triggered the action [4][5]. 2. node: The specific node that is being dragged [1][4]. 3. nodes: An array containing all nodes currently being dragged [4][5]. Usage Example: You can pass these handlers directly to the ReactFlow component: const onNodeDragStart = (event, node, nodes) => { console.log('Started dragging node:', node.id); }; const onNodeDragStop = (event, node, nodes) => { console.log('Stopped dragging node:', node.id); }; These events are part of the standard interaction properties available on the ReactFlow component [1][6].

Record one undo snapshot per node-drag gesture.
onNodesChange applies drag position changes but does not call snapshot(). Add onNodeDragStart to <ReactFlow> and call snapshot() once there. Do not snapshot each intermediate onNodesChange event.

Generate a collision-free node ID.
The module-level idCounter initializes to 100, so the first generated ID is n101. Both import paths preserve n.id without updating the counter. If an imported graph contains n101, duplication creates a second node with n101. Generate IDs against the current nodes set, or use a collision-resistant ID source.
