# ODGS Conformance Rules (Normative)

## 1. Scope
This document defines the normative requirements for achieving compliance with the Open Data Governance Standard (ODGS) regarding runtime semantic verification and administrative recusal.

## 2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

## 3. Core Conformance Requirements

### 3.1 Semantic Decoupling
Any system claiming ODGS conformance SHALL strictly decouple its policy definitions (The Legislative Plane) from its execution logic (The Physical Plane). Hard-coding legal or business definitions within the execution layer constitutes a non-conformance.

### 3.2 The Ontology Baseline
The system MUST validate incoming data schemas against a cryptographically hashed version of the governing W3C OWL/RDF ontology (`ontology_graph.owl`). 

### 3.3 Administrative Recusal (The "Hard Stop")
If the incoming data payload fails to mathematically align with the governed semantic definition, the ODGS Interceptor SHALL execute a "Hard Stop". 
* The system MUST NOT attempt to probabilistically impute, infer, or bypass the missing or mismatched definition.
* The system SHALL enforce the principle of "Silence over Error".

### 3.4 Forensic Sovereignty (Article 12 Compliance)
Upon triggering an Administrative Recusal, the system MUST generate a cryptographic event log.
* The log SHALL be written directly to the Client's sovereign storage (e.g., a private Git repository).
* The ODGS mechanism MUST NOT transmit the underlying raw data payload to external third-party audit databases (Zero-Knowledge Auditing).
