Things that run, kept here because a contract is easier to read as working code than as prose.

**Nothing here is part of the control plane.** The control plane decides and never touches a
machine ([README](../README.md)); everything in this directory runs *on* a machine and touches it.
These are reference implementations of contracts the control plane defines, and a real one ships
with the module that ships the software it configures.
