Part 1: Reproducible Foundations

Install Nix, lock a development environment, and prove the tests reject a defect.

Three chapters · approximately 3–5 focused hours, plus downloads and cloud setup. Stop after each verification gate. Paid model calls are optional until Part 3; cloud capacity and KVM are needed for the full capstone.

Chapter	Deliverable
01 · Nix on Your Mac	Separate reproducible dependencies from isolation, then install and verify Nix without replacing macOS.
02 · Lock the Environment	Create a devenv project, declare tools, freeze its inputs, and prove what the lockfile does.
03 · Tests That Push Back	Run a deterministic application suite and prove the gate catches a deliberate defect.

The next part consumes the evidence from this one. Do not advance on an assumed pass.
