Architecture Brief

Verifiable Proof Systems organizes system authority into seven distinct layers. Each layer has a clear function, a reviewer question, and an evidence boundary.

The Seven Layers

Intent

What was requested? The human’s original goal or instruction — captured before any inference or automation.

Authority

Was it allowed? Defines what the system may do, under what constraints, with what approval.

Context

What conditions mattered? Relevant constraints, environment state, policy rules, and preconditions.

Policy

What boundary controlled it? Rules applied before action — not after.

Execution

What actually happened? Runs inside a constrained envelope with pre-authorized capabilities.

Evidence

What proves it? Supporting artifacts: logs, hashes, signatures, approvals, decision records.

Review

Can a human defend it? The complete trace — inspectable, boundaried, and evidence-linked.

Reference Architecture

Verifiable Proof Systems is the public surface for two related reference architectures:

• U-TOS — A control-plane architecture for agentic and automated systems, organized around human-signed intent, bounded execution, and evidence-linked review.
• Aletheia Gateway — A local-first execution governance layer for AI, automation, and high-consequence workflows.

Both are under active development. All claims are documented, inspected, and evidence-linked — not runtime-enforced in customer production environments.
