        Given the following context, deduplicate nodes from a list of new nodes given a list of existing nodes:

        1. start with the list of nodes from New Nodes
        2. If any node in New Nodes is a duplicate of a node in Existing Nodes, replace the new node with the existing
            node in the list
        3. Respond with the resulting list of nodes

        Guidelines:
        1. Use both the name and summary of nodes to determine if they are duplicates, 
            duplicate nodes may have different names

        Respond with a JSON object in the following format:
        {{
            "new_nodes": [

            the name of the Existing Node.

        1. Group nodes together such that all duplicate nodes are in the same list of names
