What this example demonstrates
One work order has an owner and three states. Changing its status moves it to the relevant column and records the latest action. Reset restores the starting example. All data is fictional, stays in this browser view and disappears when the page reloads.
What a real application also needs
Authentication, permissions, persistent storage, concurrent edits, history and integrations need their own design. This small example helps explain the workflow discussion; it is not a finished business product.
