Incorrect (multiple queries, overfetching):

// app/routes/posts.js
export default class PostsRoute extends Route {
  @service store;

  async model() {
    // Loads all posts (could be thousands)
    const response = await this.store.request({ url: '/posts' });
    const posts = response.content.data;

    // Then filters in memory
    return posts.filter((post) => post.attributes.status === 'published');
  }
}
