Engineering Principles

Software is an artifact of a human-authored coordination system.

The quality of software reflects the quality of the coordination system that produced it.

Purpose

The platform should embody the same principles it measures.

The Align platform exists to observe, evaluate, and predict the behavior of coordination systems.

Its engineering system is therefore evaluated using the same five dimensions the platform applies to every other coordination system.

These are not coding conventions or implementation preferences.

They are architectural principles governing how the platform is built, how decisions are made, how evidence is preserved, how failures are contained, and how the system evolves.

Human engineers and AI engineering agents are expected to apply these principles consistently throughout the evolution of the platform.

The Observation Model

The Five Engineering Principles

Each principle describes one observable dimension of engineering health.

The architectural laws are intended to be remembered. The individual principle pages explain why each law exists, how the principle can be observed, and how it should guide implementation.

Engineering Health

The principles reinforce one another.

These dimensions are described independently, but they do not operate independently.

Clear authority improves traceability. Traceability exposes constraints. Visible constraints make failures easier to contain. Contained failures make safe adaptation possible.

Canonical Principle

Together, the five dimensions define the engineering health of the Align platform.
