The situation

Priya forwards a long message from Aisha Rahman: her RoboSweep X2 from order 5521 stopped charging and she wants a replacement or a refund. Before an agent reads it, Priya wants five things done automatically: sort it into a queue, find tickets like it, attach the right help article, pick out the order number and product, and write a one-line summary.

Each is a named NLP task with its own small open model. This lesson does all five on Aisha's ticket, then again in one hosted call.
