Architecture

Constitutional runtime and evidence control layer for intelligence that must remain human-sovereign and auditable.

Stratum Model

The ETHRAEON constitutional runtime operates across six strata, from Sovereign Substrate at the base to Public Interface at the surface. Each stratum has a defined role, governance posture, and evidence chain.

Sovereign Substrate anchors the runtime. Arrows ascend toward the public surface.

Stratum 1 - Public Interface

Command Deck and Public Estate

Customer-facing surfaces, investor access, partner portals, and the governed AI interaction layer. Reflects the real architecture without exposing raw machinery.

Stratum 2 - Product

Vesper and Governed Intelligence Surfaces

Vesper operator surface, compliance dashboard, fidelity check, and the constitutional runtime product layer accessible to authorized users.

Stratum 3 - Integration

Worker Infrastructure and API Layer

Stripe, DocuSign, inbox routing, and external system integration. HMAC-verified, D1-persisted, wrong-account requests refused.

Stratum 4 - Operations

Constitutional Runtime Foundation

Estate memory substrate, orchestration receipts, directive ledger, and evidence chain. Append-only, SHA-256 dual-hashed, OpenTimestamps anchored.

Stratum 5 - Agent

Governed Agent Execution Layer

Constitutional agent runtime. Human-sovereign override at every reasoning layer. Evidence-sealed execution traces. Fail-closed per command, no halt-and-wait.

Stratum 6 - Infrastructure

Constitutional Runtime and Evidence Control

The full constitutional runtime and evidence control layer AND kit framework orchestration. Distributed across Cloudflare Workers, D1, KV, R2, and sovereign edge compute.

Core Capabilities

Reasoning Engine

High-integrity governance reasoning and anomaly detection substrate. Human-sovereign at every step.

Decision Tracing

Append-only, tamper-evident decision trace from prompt to output. Every governance act is chain-anchored and audit-ready.

Cross-Jurisdiction Translation

Legal, regulatory, and operational translation across jurisdiction boundaries with evidence of provenance.

Drift Computation

Constitutional drift detection and correction. Constitutional Runtime runtime engine. Continuous semantic alignment.

Evidence Encoding

Secure evidence encoding and verification layer. SHA-256/SHA-512 dual-hash. Append-only ledger.

Safety Boundary

Containment and policy enforcement layer. Constitutional constraints that cannot be reasoned around or deprecated.

IP Foundation

16 filed provisional patents covering the constitutional runtime architecture. 73 technical specifications across 9 patent families. The governance layer is formally protected as part of the ETHRAEON IP position.

Infrastructure and Deployment

ETHRAEON runs on three infrastructure layers, each a distinct concern. The canonical source repository drives continuous deployment: every merge to the main branch triggers GitHub Actions workflows that publish to the edge. Cloudflare is the edge layer: Pages for the public surfaces, Workers for the runtime services, DNS across the registered domains, and Zero-Trust Access for the private surfaces. A sovereign VPS in Iceland (1984.is, geothermal-powered) is the metal: a Caddy reverse proxy fronting the substrates and runtime services under a preflight-and-rollback deployment discipline.

Infrastructure is infrastructure. ETHRAEON is the constitutional runtime and evidence control layer that runs on it. A surface being live is not the same as the governance being wired; the two are kept distinct by design.
