SSDD: A Sovereign Deterministic Architecture for Scalable Distributed Computing This repository contains the foundational theoretical framework and simulation results for SSDD, an architecture designed to eliminate architectural entropy in hyper-scale distributed fabrics. Unlike traditional systems that mask non-determinism via software, SSDD eliminates it at the hardware-protocol interface. Key Architectural Components: Sovereign Sidecar (SSC): A temporal-to-logical buffer that ensures the execution engine remains isolated from network entropy. SPER (Sovereign Purity Enforcement Regime): A regime that treats Amplitude, Timing, Stability, and Throughput as strictly orthogonal domains to prevent cross-domain leakage of non-determinism. Hierarchical Furnace Topology: A 3-tier aggregation structure that enables scaling to a million chiplets while maintaining a decision window ($T_{decision}$) of $\le 73$ ps. Binary Audit Trail: A non-repudiable SHA-256 based ledger for forensic verification and deterministic replay. Validation Results: Order Invariance: 100% hash equality across $10^6$ simulated nodes. Failure Closure: System stability preserved under 20% random node failure via deterministic null-space mapping.
