**As an** administrator configuring any work package type (sub-type or plain type)
**I want to** link a type's workflow to a source type or make it independent
**so that** I can reuse the same exact workflow across many types without copying, or own my own workflow.

## Acceptance criteria

* For any type, I can set its workflow to **Linked** (choosing a source type) or Begin of the insertion**Independent**. 

* End of the insertion Begin of the deletion **Independent**.End of the deletion A sub-type defaults to Linked to its Begin of the insertionparentEnd of the insertion Begin of the deletion parent. _(F1-C0)_End of the deletion

* A Linked workflow resolves to its source at runtime; when I change the source's workflow, every linked type reflects it Begin of the insertionimmediatelyEnd of the insertion Begin of the deletion immediately. _(F1-C1)_End of the deletion

* When I switch a workflow to Independent, the system copies the current source's workflow once as a starting point and then severs the Begin of the insertionlinkEnd of the insertion Begin of the deletion link. _(F1-C2)_End of the deletion

* The workflow matrix of a Linked type is read-only; I edit the owning (Independent) type instead, and the admin shows which source it is linked Begin of the insertiontoEnd of the insertion Begin of the deletion to. _(F1-C3)_End of the deletion

* The system prevents me from creating a cyclic dependency between workflow Begin of the insertionsourcesEnd of the insertion Begin of the deletion sources. _(F0-C2)_End of the deletion

* Linking a workflow never changes the type's display name or Begin of the insertioncolorEnd of the insertion Begin of the deletion color. _(F0-C3)_End of the deletion


## Permissions and visibility considerations

* **To whom is this feature visible?** Users who can manage workflows or sub-types (admins; later project admins via `:manage_subtypes` for project-owned sub-types).

* **When is it not visible?** Feature flag turned off, users without management rights. Linked types are read-only in the workflow matrix.
