 - `ACTIVE`: The stack is fully usable. This is the default state for a new stack.
 - `DEPRECATED`: The stack is still usable, but a prominent warning will be logged during staging and starting of applications. This is to inform users about the upcoming removal of the stack.
-- `LOCKED`: The stack cannot be used for new applications. Existing applications using this stack can still be updated, restarted, and scaled. This state is intended to prevent new adoption of the stack.
+- `RESTRICTED`: The stack cannot be used for new applications. Existing applications using this stack can still be updated, restarted, and scaled. This state is intended to prevent new adoption of the stack.
 - `DISABLED`: The stack cannot be used for staging or restaging any application. Existing applications will continue to run, but they cannot be updated. Restarting and scaling of existing apps using the disabled stack is still possible.
 
 This requires extending the `stacks` table in the database with a `state` column. The API endpoints for managing and listing stacks will also need to be updated to expose and allow modification of this new field. Client libraries and the `cf` CLI should be updated to display the stack's state.

 - When an application is staged or restaged, the API will check the state of the used stack.
 - If the state is `DEPRECATED`, a warning message will be added to the logs.
-- If the state is `LOCKED`, staging a *new* application will fail with an error.
+- If the state is `RESTRICTED`, staging a *new* application will fail with an error.
 - If the state is `DISABLED`, staging or restaging *any* application will fail with an error.
 
 To improve communication with developers, the existing `description` field of a stack will be leveraged. The content of the `description` field should be included in any warning or error message related to the stack's state. This allows operators to provide context, migration guides, or links to further documentation.
