NMCA Original Blueprint (46 pages, April 20, 2025)

This page documents the multimodal cognitive architecture I first published as the original 46-page NMCA blueprint on April 20, 2025.

A copy was sent to the USPTO as prior art. No patent was pursued.

I chose to release that version — and all subsequent versions — freely to the public.

I did this because the implications of proprietary, corporate-controlled systems built on visual thought / internal 3D simulation as a core of cognition are too large to leave exclusively in private hands.

The work is therefore placed in the public record so that the chronological priority and the original architectural claims remain visible.

The final specification is the 471-page NMCA blueprint published in 2026. Earlier versions remain preserved as separate historical records.

Publication Chronology

What was disclosed on April 20, 2025

• Internal 3D Scene Builder used to simulate tasks visually and model interactions
• Persistent internal visual/3D scene representation for reasoning
• Memory encoding that stores visual scenes for future recall
• Internal visual simulation synchronized with observation
• Symbolic scene representations tied to memory and belief structures
• Contradiction detection and belief updating
• Planning inside the 3D spatial model
• Simulation of routes and actions before execution
• Feedback from real observation that triggers replanning
• Multiple simulation branches
• Explicit computational loop: Input → Internal Simulation → Action → Reflective Update

Human thought can keep a scene. Current LLMs keep text and files. Those are not the same thing.

Thought requires a persistent, re-enterable internal space.

It is the first public specification of the same claim later expanded to the 128-module NMCA document:

This first version was publicly disclosed by Derek Van Derven on April 20, 2025. No earlier public document containing this same unified combination as a single architecture has been identified.
