Architecture

A constitutional runtime and evidence-control layer that governs consequences around the models, tools, systems, and presentation layers an organization already uses.

Stratum Model

The ETHRAEON constitutional runtime operates across six strata, from the constitutional runtime foundation at the base to the public interface at the surface. Each stratum has a defined role, governance posture, and evidence chain.

The constitutional runtime foundation anchors the model. 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.

Public estate index

Stratum 2 - Product

Governed Customer Surfaces and Internal Truth Checks

Customer products expose their own governed workflows and evidence. VESPER is ETHRAEON's internal current-truth and fidelity-check instrument; VESPA is the private owner application.

Stratum 3 - Integration

Worker Infrastructure and API Layer

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

Worker and API layer

Stratum 4 - Operations

Constitutional Runtime Foundation

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

Governance and evidence

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.

Agent constellation

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.

Constitutional runtime surface

Internal model: the six public strata map to ETHRAEON's internal layered runtime model. The detailed layer specification is maintained under governed disclosure. Request the architecture briefing for the governed detail.

Core Capabilities

ETHRAEON governs the workload in the customer's existing model and stack. The control layer evaluates authority and policy, constrains permitted execution, records evidence, and supports review and recovery while the connected workload stays in the customer's chosen tooling. EUDS is ETHRAEON's authored design system and remains optional for governed operation.

Reasoning Engine

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

Decision Tracing

Append-only, tamper-evident decision trace from prompt to output. Every governance act is chain-anchored and independently verifiable from the evidence ledger.

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. Cryptographic 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 applications covering the constitutional runtime architecture. 75 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. Releases use verified direct provider tooling with preflight, immutable build identification, live-origin checks, and rollback evidence. Cloudflare is the edge layer: Pages for public surfaces, Workers for runtime services, DNS across registered domains, and Zero-Trust Access for private surfaces. A sovereign VPS in Iceland is the metal, with Caddy fronting the hosted runtime services under the same verification 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.
