A merchant Enrollment lets one Account operate in one exact product instance.
Enrollment = Account × Product Instance
It carries instance-specific status, onboarding, capabilities, commission, listing-approval mode, and storefront limits. Fiton Local and another product instance therefore create separate enrollments even when the seller reuses the same profile.
Cardinality
There can be only one current enrollment for the same account and product-instance pair. A current enrollment is pending, active, or suspended. Archived or rejected history does not create a second active bond.
What belongs here
Storefronts and Listings are scoped to the enrollment and its product instance. That is what prevents DJ Cloths content in one app from accidentally becoming the same storefront or listing in another app.
