The situation

It is Tuesday 2 June 2026, week 8, day two of shadow mode. Overnight the agent proposed a $129.00 refund for Aisha's robot vacuum, R-1001.

Marta asks: "What did that run cost, and why did it take so long?" Priya asks: "When it decided on $129, what had it seen?" The simulator's audit trail lists what the systems did: an order read, a return created. It says nothing about the model's calls, tokens, timings or inputs.

This lesson records all of that for every run, and traces R-1001 from start to finish.

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.
