The situation

It is Monday 24 August 2026, week 13, 09:00 UTC. The queue opens and forty tickets arrive in a few seconds (simulated), all through Lesson 1's gateway. Tomasz watches the logs; Joel watches the bill.

You follow T-1001, Ana Duarte's duplicate charge of 288 USD, through four questions. How long may a call take? What if the provider says "too many requests", or is down? And how do you avoid paying twice for one answer, or for a runaway script?

At 09:00 the gateway (blue, your system) meets four questions at once: how long a call may take, how much it may send, what if the provider is down (amber, uncertain), and what it costs.
