// Submit Work: Only assigned artist, in progress or retake
canSubmitWork = task.assigned_user_id === currentUser.id 
                && (task.status === 'in_progress' || task.status === 'retake')

// Reassign: Only coordinators and admins
canReassign = currentUser.is_admin || currentUser.role === 'coordinator'
```
