I’m marking this feature request as resolved. Starting from version 0.20.0, we now offer a bundle called Constraint-Augmented Generation (CAG) that supports multi-table constraints.
For more information, see the CAG bundle page. Browse through the existing multi-table constraints here. Please feel free to start a new thread if there’s a specific type of multi-table constraint logic you’re encountering that is not yet supported.
For the specific logic described in this issue, I’ve created a new feature request here.
