Document Expected Alethia Behavior for a Checkout Test Suite

Problem/Feature Description

The e-commerce team at Brightcart is writing automated E2E tests using Alethia for their checkout flow. A developer has drafted a test that navigates to the cart page, fills in a shipping address, and clicks the "Place Order" button. When a colleague ran the test, the "Place Order" step did not execute — instead, the PlanRun returned a result with an unexpected outcome for that step.

Your task is to write a guide for the Brightcart QA team explaining what happened and what the correct way to handle this situation is. The guide should also include the correctly written test instructions for the checkout flow and a description of how the team should respond when they encounter this outcome in their CI run.
