Overall, this looks good!
If it helps to have a user story for patrollers and others in similar roles, I'd offer something like this: As an experienced editor who interacts with newcomers during the article creation process, I want to have tools that allow me to quickly identify submissions appropriate for the encyclopedia so that they can be approved and refined. For submissions that require additional work before they will be suitable for Wikipedia, I want tools to help me quickly assist newcomers in completing this work. Lastly, for submissions that will not be suitable for Wikipedia, I want tools to help me quickly discard them so that I can focus my efforts elsewhere.
Under the goals section, a small quibble with this line: Minimize bad articles created, to reduce content moderation burden. Bad articles being created isn't the only aspect of the current system that results in more of a moderation burden. Bad drafts increase it, too, even if they never get beyond AfC. And good (in the sense of "on a notable/suitable topic") articles/drafts increase it when they're flawed in ways that increase the time it takes to review them (such as having excess references).
