import { z } from "zod/v4";
import { StateGraph } from "@langchain/langgraph";
import { registry as langgraphMeta } from "@langchain/langgraph/zod";

const StateSchema = z.object({
  exampleList: z.array(z.number())
    .register(langgraphMeta, {
      reducer: {
        schema: z.number(),
        fn: (a, b) => a.concat([b])
     },
     default: () => [],
   }),
});

const graph = new StateGraph(StateSchema)
