- Add authorize?: false to user_fixture so register_with_password bypasses policy check in test context - Add require Ash.Query so Ash.Query.filter macro works in count_likes - Replace nonexistent Ash.ForbiddenField.forbidden?/1 with match?/2 - Fix stale tweet struct in :like noop case by reloading from DB Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
