The developer uploaded a baseline and thinks the API is live

A developer used Create Baseline and told the customer the program is now an API. What do I tell them?

Create Baseline uploads members so Hub can analyze calls, database use, and file operations. It is inventory. Create API is the step that registers the program as a Hub asset, and Add Test Asset is how they send JSON from the IDE. Nothing is callable for a partner until the API asset exists and is published. I can stay on the thread while they redo the right action.
