+"""work-item view check: verify ``work_item_to_kanban`` reads UI-critical
+fields via ``WorkItemContextView``.
+
+Covers:
+* Rendering when values live ONLY on ``work_item.metadata`` (Step 9 mirror
+  result — post-migration path)
+* Rendering when values live ONLY on ``linked_task.metadata`` (fallback
+  path — pre-migration tasks still work)
+* Rendering when values live on BOTH sides (work_item wins)
+
+Fields tested: progress_log, work_item_role_name, employee_prompt_context,
+employee_delta_context.
