OpenOPC/tests/test_kanban_work_item_view.py

"""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.
