1. Purpose
This document defines a pragmatic, minimum-viable audit and governance framework for organizations deploying knowledge-centric AI systems in regulated or high-trust environments.
It is intentionally lightweight, but structurally rigorous. The framework is not designed to introduce additional bureaucracy, nor to prescribe a specific technology stack.
Its purpose is to establish defensible architectural principles that enable organizations to deploy AI systems responsibly while retaining control, accountability, and auditability.
The primary goal is defensibility:
toward auditors, regulators, customers, partners, and internal governance bodies.
By focusing on explicit knowledge structures, clear responsibility boundaries, and inspectable system behavior, the framework provides a practical foundation for trustworthy AI operations under real-world regulatory and operational constraints.

Sovereign AI
Sovereign AI is about independence from hyperscalers and European values in AI – sol4data implements it: Fully European components (hosting, data management, interfaces) without quality loss, with customer choice between on-premises and cloud. Economically optimal often in the cloud for efficient operations, scaling, and maintenance. Core: Architectural freedom, technological diversity, data sovereignty, and economic focus.
