The framework is built from a small number of load-bearing concepts. Each has its own page below: a short summary, a link to the essay that develops the idea at length, and cross-references to the relevant Library section.

The pages are reference-style by design. The goal is the shape of each idea and its connection to neighboring ideas, not exhaustive treatment. Long-form development lives in the essays and in the source documents at the project’s repository root.

Read the concepts as the framework’s table of contents in graph form. Most readers won’t read straight through — they’ll arrive at one concept through an essay or a search, follow the cross-links to neighboring concepts, and let the structure assemble itself in their mind over multiple visits. That’s how the page is designed to be used.

Concept pages are listed below in reading order. Three-Layer Model and the OS Hypothesis are the most foundational; the rest are the architectural features built on top of them.
