AGORIA 3.4: A Unified Governance Framework for Cognitive and Cyber-Physical Systems with Reinforced Formal Guarantees

Abstract

Hybrid AI systems that combine cognitive decision-making with physical actuation pose unprecedented challenges for governance, safety, and certification. AGORIA 3.4 presents a unified architectural framework that bridges cognitive governance (AGORIA v1.3) and cyber-physical governance (AGORIA v1.6) into a coherent, certifiable solution for safety-critical applications.Core Innovation: Controlled IgnoranceAGORIA introduces the principle of controlled ignorance—the deliberate, verifiable, and structural restriction of information accessible to each system layer beyond what is strictly required for its formal responsibility. This architectural invariant reduces cognitive coupling, limits attack surfaces, enables independent certification, and ensures that no single component can subvert the safety-governance chain. Zero-knowledge proofs provide cryptographic enforcement of this separation.Four-Layer ArchitectureThe framework organizes systems into four formally interconnected layers: STRATEGOS: Strategic cognitive governance via Choquet integral aggregation (~100 ms)GENESIS: Tactical planning with DSL→STL translation and ZK certificate generation (<50 ms)NEXUS: Bounded verification independent of semantic complexity (<250 µs)HSL++: Hardware-enforced physical safety via Control Barrier Functions (100 µs–kHz) Formal GuaranteesAGORIA provides four normative amendments with mathematical proofs: Robust Invariance via CBF with explicit feasibility hypothesis and statistically calibrated margins (Theorem 1)Bounded WCET Verification via succinct ZK proofs on constrained platforms (Proposition 2)Practical Stability under Lipschitz-continuous governance parameter variation (Theorem 2)Conservative Semantic Bridge from domain-specific language to decidable STL fragment (Theorem 3) Validation and CertificationExperimental validation covers three scenarios: autonomous vehicle (1000 trials), surgical robot (500 trials), and multi-agent factory (100 trials). AGORIA achieves zero safety violations while maintaining bounded worst-case execution time (<250 µs). A case study on multi-source aeronautical navigation (ILS, VOR, GBAS, DME) demonstrates framework genericity.The architecture enables hybrid certification compatible with: Functional safety standards (ISO 26262 ASIL D, IEC 61508 SIL 3)AI regulatory requirements (EU AI Act 2024/1689, UL 4600)Industrial cybersecurity (IEC 62443) Related Publications AGORIA v1.3: Cognitive Governance (Zenodo, 2025)AGORIA v1.6: Cyber-Physical Governance (Zenodo, 2025)
