1. What AGI Actually Requires (A Structural Definition)

In open discussions, “AGI” is often described as:

a very large model,

a universal problem solver,

a human‑level agent,

a system based on subjective experience.

These definitions contradict each other and do not provide an engineering criterion.

A structural definition of AGI:

AGI = a system with a stable vertical cognitive architecture capable of generating, evaluating, and refining its own direction (S1), constraints (S2), knowledge (S3), and honest integration (S4), and capable of completing a full reasoning cycle (S1–S11) without collapse.

This definition does not depend on:

model size,

training data,

biological analogies,

philosophical assumptions.

It depends only on structure .
