The situation
Wednesday 7 October 2026, week 5. Nare asks: "Is the sleep lab free the week of 19 October, and how many participants will the nap study have?" One half lives in Tomas's calendar, the other in her notes.
Module 6's host handles two servers. But Nare uses four AI applications, each needing every server configured, and Priya wants the same servers with nothing that writes. This lesson composes servers: one host over many, one server in front of many, then a retrieval server behind it.
