System of Eternity (SOE): Architecture Design v2 — Institutional Mechanisms Integration Snapshot

This record provides the updated System of Eternity (SOE) Governance Architecture synthesis, superseding the prior Architecture Design v2 Integration Snapshot as the current architecture planning base. SOE Governance Architecture v2.2 specifies a nine-part architecture consisting of C00 Program Index plus C01–C08 functional components: Trust Integrity Layer, Recovery Engine, Disturbance Buffer, Stability Lock Mechanism, Structural Support Layer, Governance Module, Meta Governance Layer, and Coordination Layer. This version incorporates post-review component updates and simulation-constrained findings from v18, v19, and v19b. Major updates include: the C02 v2.1 T-G loop break condition; C04 v2.3 finding that federation C04 S-threshold Trigger A is not applicable; C05 v2.1 heterogeneous node classes H/I/A; and C07 v2.2 assignment of Psi_extended with cluster variance as the mandatory federation stress detector under the current tested architecture. Key simulation-constrained findings include: star topology remains disallowed under current SOE deployment assumptions; two hubs are insufficient in tested hub-redundant configurations; three hubs are the minimum tested hub-redundancy mitigation; federation contains local stress under tested regimes but requires C07 Psi_extended monitoring; and lambda = 0.1 is locked for the federation cluster-variance term. This document is architecture-ready and intended as the planning base for the SOE Grand Simulation Specification. It is not deployment-ready. Open calibration items include recovery gain k_b, governance suppression alpha_gov, trust coupling coefficients, governance growth/decay rates, Psi weights and thresholds, tau_smooth, asynchronous update intervals, message loss, node-class proxy weights, and real-world timescale mapping. Version note: This record is a new version of the prior SOE Architecture Design v2 Integration Snapshot. It supersedes the v2.0 snapshot as the current Governance Architecture planning base and incorporates post-review updates through C04 v2.3, C05 v2.1, C07 v2.2, and the v18/v19/v19b simulation findings.
