Content & Retrieval

Module 2 established that retrieval fetches passages. This module teaches you to write them: answer passages that survive extraction, entity naming that matches how machines read, information gain that makes a page worth fetching at all, and the architecture and freshness habits that keep it working. Every exercise uses the briefs you starred in Module 3.

Prerequisite: Modules 1-3. By the end you can rewrite a page's core passages for extraction, name entities the way retrieval reads them, add genuine information gain, and keep the structure honest over time.
