> A draft with a blocking problem is refused with 422 `invalid_automation`, and the answer lists every problem in `error.problems`.

> Every email step needs a published template with an unsubscribe link and a sender this key or app may send as. A template that cannot be filled in without a contact’s name is a problem too, because many contacts have no name: give the value a fallback.

> Publishing when the plan’s live automations are all in use answers 403 `automation_limit_reached`.

> Publishing an unchanged draft again makes no new version. It turns a paused automation back on.
