but the Wrangler rule is robust and creates the child Pico anyway. Can I deduce that the second required argument is a “prototype” Pico (whose rulesets would be installed in the new Pico by Wrangler)? How do I get a prototype Pico? Do I create it myself? Do I refer to it by name in the 2nd argument, or by ECI?
