The Readme follows worked connections between methods; the Preface explains how the methods connect, which knowledge they require and how to revise a physical account.

The reference code PHY names this DPF. Its numbers are stable pattern addresses; § shows position within a Part. The methods can be used separately or in longer routes with mathematical and computational contributions.

This publication belongs to the Foundational Thinking DPF Suite. Its Reference explains those connections and the available publications. References such as B.5.MPC and C.29 name patterns in FPF Core. Open the cited body when its contribution is needed; revisit a receiving conclusion when that contribution changes.
