Understanding `Effect.scoped` Usage

import { NodeRuntime } from "@effect/platform-node";
import * as Http from "@effect/platform/HttpClient";
import { Schema } from "@effect/schema";
import { Console, Effect } from "effect";

const Post = Schema.struct({
  id: Schema.number,
  title: Schema.string,
});

/*
const getPostAndValidate: Effect.Effect<{
    readonly id: number;
    readonly title: string;
}, Http.error.HttpClientError | ParseError, never>
*/
const getPostAndValidate = Http.request
  .get("https://jsonplaceholder.typicode.com/posts/1")
  .pipe(
    Http.client.fetch,
    Effect.andThen(Http.response.schemaBodyJson(Post)),
    Effect.scoped
  );

NodeRuntime.runMain(getPostAndValidate.pipe(Effect.andThen(Console.log)));
/*
Output:
{
  id: 1,
  title: 'sunt aut facere repellat provident occaecati excepturi optio reprehenderit'
}
