DT4I
Architecture

From industrial reality to decision support.

This describes the DT4I architecture specifically — it is not a claim of a universal runtime that generalizes to unrelated domains. Atlas is the execution layer built on top of it.

System Flow

Industrial reality becomes decision support in seven steps.

Separation of Concerns

Methodology, architecture, implementation, and product are kept distinct.

DT4I separates four layers: methodology, reference architecture, reference implementations, and commercial products.

This separation allows the architecture to remain stable while products built on top of it evolve independently. A commercial product can change its interface, pricing, or scope without requiring a change to the underlying methodology — and the methodology can be revised without breaking a specific implementation's contract with its architecture.

Layer Stack

Each layer does one job.

[02]Evidence layerNormalizes signals into sourced, timestamped evidence records.
[03]Industrial entity graphSites, companies, routes, regulations, and the dependencies between them.
[04]Scenario engineConstructs and compares named scenarios against the entity graph.
[05]Risk registerTracks identified risks, their status, and which evidence supports them.
[06]Decision workspaceWhere a specific decision is framed against the current map and scenarios.
[07]Update historyVersioned record of how the map, evidence, and scenarios changed over time.
Layer Detail

What each layer is responsible for.

01
Input signals

Ingestion points for structured and unstructured source material.

02
Evidence layer

Normalizes signals into sourced, timestamped evidence records.

03
Industrial entity graph

Sites, companies, routes, regulations, and the dependencies between them.

04
Scenario engine

Constructs and compares named scenarios against the entity graph.

05
Risk register

Tracks identified risks, their status, and which evidence supports them.

06
Decision workspace

Where a specific decision is framed against the current map and scenarios.

07
Update history

Versioned record of how the map, evidence, and scenarios changed over time.
