## 1. Executive Summary

The Open Data Governance Standard (ODGS) Protocol v4.0.0 has been audited for compliance with:

- **NEN Standards Committee 381 525** (Data, Data Management, Cloud and Edge)
- **EU AI Act** (Regulation 2024/1689), Articles 10 and 12
- **ISO/IEC 42001:2023** (Artificial Intelligence — Management System)
- **GDPR** (Regulation 2016/679), Articles 5, 25, and 30

The v4.0.0 release implements a **"Universal Validation Primitive"** architecture — a headless, privacy-native, vendor-neutral enforcement layer that provides:

| Capability | Implementation | Standard Reference |
|---|---|---|
| Tri-Partite Binding | SHA-256 cryptographic binding of Input + Definition + Configuration | EU AI Act Art. 12 |
| Sovereign Handshake | Content-addressed integrity verification against harvested definitions | ISO 42001 B.7 |
| Hard Stop / Administrative Recusal | Runtime prevention of non-compliant AI decisions | EU AI Act Art. 10 |
| Immutable Audit Trail | Git-backed forensic evidence ledger | ISO 42001 B.4 |
| 86% Rule Enforceability | 87 of 101 data rules have executable `logic_expression` fields | NEN 381 525 |
