# Workspace draftable contract

Moved. The `BelongsToWorkspace` trait, the `WorkspaceRegistry`, and the `assertWorkspaceDraftableContract` Pest helper all live in the `capell/publishing-studio` add-on package.

➡ See [docs.capell.app/publishing-studio-draftable-contract](https://docs.capell.app/publishing-studio-draftable-contract/) (canonical) or [`packages/publishing-studio/docs/publishing-studio-draftable-contract.md`](https://github.com/capell-app/capell-packages/blob/4.x/packages/publishing-studio/docs/publishing-studio-draftable-contract.md) in `capell-packages`.
