The situation
The answer engine is live. Priya forwards two complaints: one customer waited "ages", another got a reply citing the wrong article. Marta asks what the week cost. Dev asks whether the failures are one bug or several.
Lesson 1 tested the engine before release; this lesson watches it after. You will run the forty labelled tickets as one simulated week, Monday 5 to Friday 9 October, and trace ticket 4, "When will my refund show up on my card?", end to end. A fake model with labelled simulated timings keeps the numbers repeatable; two calls are real.
