Stewardship Pattern Language — Overview

The Stewardship Pattern Language is a timeless vocabulary for describing recurring human situations that any system caring for human understanding will encounter. It is the bridge between the Constitution, the Human Stewardship Guidelines, and product architecture.

Where it sits#

PosterityOS Constitution   →  WHAT the system is
Human Stewardship Guides   →  HOW responsible people build it
Stewardship Pattern Lang.  →  WHICH recurring human situations recur
Product Architecture       →  which patterns each product expresses
Implementation             →  how each product expresses them

Patterns are implementation-independent. HeadsUp, LOX, Atlas, a library, a hospital records office, and a system yet to be built should all be able to inherit the same pattern and express it in whatever medium they have.

• Products may not redefine patterns; they may only express them.
