D10Z-MIZAN-TTA: A Cryptographic Architecture for Food System Sovereignty in Water-Scarce Economies — Framework Specification v1.0

This paper presents D10Z-MIZAN-TTA, a three-layer computational architecture designed to transform food system governance in water-scarce economies. Developed for the Kingdom of Saudi Arabia and extensible to GCC/MENA, the framework integrates: (Layer 0) D10Z, a multi-objective optimization engine for strategic resource allocation; (Layer 1) MIZAN, a cryptographic attestation protocol replacing institutional audit with mathematical proof; and (Layer 2) TTA, a deterministic governance system with executable thresholds and accountable human overrides. The framework addresses a critical failure mode in traditional food security policy: the mismatch between strategic planning horizons (5–10 years) and the operational decision velocity required by supply shocks (24–72 hours). By computationalizing the “decision stack” — from sensor data to ministerial action — D10Z-MIZAN-TTA claims 10–21× faster decision validation while maintaining verifiability and accountable override paths.Falsifier (speed): if median time-to-validated-decision does not improve by ≥10× versus the baseline ministerial workflow across N≥30 shock scenarios, the claim fails. Key technical contributions include: (1) the Φ-score metric for multi-dimensional agricultural efficiency; (2) MIZAN bundles, a JSON-based cryptographic proof format for physical production claims; (3) a formally specified state machine for automated governance transitions; and (4) explicit falsification criteria enabling empirical validation of system performance. Empirical application to Saudi Arabia indicates $13.37B projected savings over 3 years and 40–60% projected resilience improvement, contingent on published falsifiers and benchmark replication.Falsifier (resilience): if a chosen resilience metric (e.g., days-of-cover under shock, recovery time, or fill-rate) does not improve by ≥40% under standardized stress tests, the claim fails. Three operational pilots are specified for 2026 deployment: Food Shock Response (≤24h decision validation), MIZAN Verification (10-farm benchmark with offline-verifiable bundles), and TTA Water Governance (Al-Ahsa Oasis threshold enforcement with auditable overrides). The framework extends to regional collective action (GCC optimization), post-quantum cryptographic hardening, and algorithmic governance ethics.
