defmodule AshDispatch.RecipientResolver.Default do
  @moduledoc """
  Default recipient resolver that raises errors.

  This is used when no custom resolver is configured. Following Elixir's
  "let it crash" philosophy, it raises explicit errors for admin/team/system
  audiences to force developers to implement proper recipient resolution.

  ## Usage

  This module is used automatically if you don't configure a resolver.
  To fix these errors, configure your own resolver:

      # config/config.exs
      config :ash_dispatch,
        recipient_resolver: MyApp.Recipients.Resolver

  See `AshDispatch.RecipientResolver` for implementation guide.
