The situation

It is Tuesday 26 May 2026, week 7. Dev has an idea: "Run the morning's ten requests through one conversation, a shift. Then the agent can see that R-1006 is Aisha repeating R-1001." You try it on the test queue.

It works, and every call gets bigger. Priya asks: "By the afternoon, will it still remember that Aisha's $129.00 refund is waiting for Marta?" This lesson traces that one fact through the shift.

The rest of this course is yours to keep

This course is bought on its own, once, and stays readable afterwards, including the parts added to it later.
