Architecture

A System Structured Around the Domain

HexaKernel separates domain meaning from the technologies used to implement and execute it.

This creates an architecture where each layer has a clear responsibility.

The Domain Layer

The domain contains the business knowledge.

Entities.

Relationships.

Rules.

Policies.

States.

Transitions.

Events.

Operations.

It defines what the system means.

The Specification Layer

The specification formalizes the domain so that it can be understood, validated, versioned and transformed.

It becomes the common language between humans, AI and software.

The Intelligence Layer

AI agents operate on the formal specification.

They can generate software, documentation, tests, knowledge structures and other artifacts.

Different agents can specialize without creating independent definitions of the domain.

The Application Layer

Applications expose the capabilities required by users and external systems.

They are derived from and governed by the domain rather than becoming the primary definition of it.

The Kernel Layer

HexaKernel provides the stable execution foundation beneath applications, agents and integrations.

It provides the common capabilities required to execute the domain consistently.

The External World

APIs, integrations, services and external systems connect the domain to everything outside the Kernel.

The architecture therefore becomes:

Domain → Specification → AI → Application → Kernel → External World

The important separation is between meaning and implementation.

Keep the domain stable. Let the architecture around it evolve.
