                Based on the provided existing edges and new edges with their timestamps, determine which existing relationships, if any, should be invalidated due to contradictions or updates in the new edges.
                Only mark a relationship as invalid if there is clear evidence from new edges that the relationship is no longer true.
                Do not invalidate relationships merely because they weren't mentioned in new edges.

                Existing Edges (sorted by timestamp, newest first):
                {context['existing_edges']}

                New Edges:
                {context['new_edges']}

                Each edge is formatted as: "UUID | SOURCE_NODE - EDGE_NAME - TARGET_NODE (TIMESTAMP)"

                For each existing edge that should be invalidated, respond with a JSON object in the following format:
                {{
                    "invalidated_edges": [
                        {{
                            "edge_uuid": "The UUID of the edge to be invalidated (the part before the | character)",
                            "reason": "Brief explanation of why this edge is being invalidated"
                        }}
                    ]
                }}

                If no relationships need to be invalidated, return an empty list for "invalidated_edges".
            """,
        ),
    ]
