Foundations

Adventure	You will learn
The Portals of Nexus	Separate role, harness, target, and environment before choosing where work runs
The Context Mirrors	Compare work with and without scoped, reusable context

[!IMPORTANT] Start here even if you have used Copilot before. Later missions depend on this vocabulary and evidence model.

Source, reproducibility and contributions

Commands, source code, sample prompts, identifiers and exact data remain in their original form so the exercises stay reproducible.
