name	ViewModel Filtering + Pagination
description	Build filterable/paginated list pages using embedded ViewModels and Scrivener.

Scope

Use this skill for search/filter/list pages backed by query params.

Checklist

• Add an embedded ViewModel in lib/app/view_model/* using use App, :view_model.
• Define embedded_schema fields for filters, and a validate/1 function that returns { :ok, options, changeset }.
• Build filtered queries using scope/2 functions and Repo.paginate/2 (Scrivener).
• In the LiveView, call validate/1 in handle_params/3, assign @form via to_form(changeset, as: "form").
• Use push_patch to keep filters in the URL and ensure invalid params raise Web.Status.NotFound.
