Operational Safety via Recursive Constraint Satisfaction

A Neuro-Symbolic Architecture for Critical Infrastructure

Stefan Paetzold | Causa Nova Research | January 2026

Abstract. Large Language Models (LLMs) operate stochastically (P < 1.0), making them inherently unreliable for safety-critical domains like public administration or industrial automation. This document introduces CausaNova, a neuro-symbolic architecture that decouples Planning (Neural) from Execution (Symbolic). By utilizing a Self-Extending Meta-DSL rooted in JSON and a Guard Resolver (SMT), we reduce "Operational Alignment" to a dynamic constraint satisfaction problem, effectively eliminating execution-layer hallucinations.

1. The Stochasticity Gap

The integration of Generative AI into deterministic environments faces a fundamental contradiction. Industrial control systems require reliability of ≈99.999%, whereas State-of-the-Art LLMs are probabilistic engines. We cannot build critical infrastructure on "maybe".

Current approaches (RAG, Chain-of-Thought) reduce error rates but do not eliminate the possibility of structural violation. CausaNova solves this by ensuring that the Neural Network never touches the execution layer directly.

2. Architecture: The Mathematical Firewall

The system enforces a strict separation of concerns:

3. The Self-Extending DSL

Unlike static code generators, CausaNova uses a recursive JSON schema. The definition of a "Form Field" or a "Database Table" is itself data, not code. This allows the system to transport logic securely across boundaries (Server to Client) without executing arbitrary code.
