Architecture

How the control plane governs execution.

Trust surfaces submit execution requests. The control plane enforces policy, signs receipts, and enables independent verification.

System Layers

Three layers of governed execution.

Policy constrains. Attestation proves. Verification trusts.

Layer 1

Policy

What gets defined before execution. Every agent action must pass through a policy gate — specifying who can act, what they can do, and under what constraints.

Layer 2

Attestation

What gets recorded after execution. The control plane signs a cryptographic receipt documenting the action, the policy it was governed by, and the compliance verdict.

Layer 3

Verification

How downstream systems consume proof. Any party can independently verify a receipt — offline, without calling back to the issuing service, and without trusting the executing agent.

Trust Surfaces

Enforce anywhere execution happens.

Any place where execution needs policy and proof can become a trust surface. The control plane is protocol-agnostic and runtime-independent.

xMandate Control Plane

xMandate Guard

Browser-level policy enforcement and attestation for AI-assisted code workflows.

API Gateways

Policy enforcement at the API boundary — gate agent actions before they reach downstream services.

Agent Runtimes

Embed attestation directly within agent execution environments for inline receipt issuance.

CI/CD Pipelines

Attach execution receipts to build and deployment flows for auditability and release gating.

MCP Adapters

Policy and proof for tool-using agents operating through the Machine-to-Agent Protocol.

A2A Bridges

Verification and trust propagation for delegated actions across multi-agent systems.

Receipt & Verification

Portable, cryptographic execution receipts.

SAR is the receipt primitive. sar-sdk is the public OSS implementation. The control plane operationalizes policy, issuance, and verification above it.

How SAR fits in

Settlement Attestation Receipts are the cryptographic primitive for auditable agent execution. Each receipt captures identity, context, compliance verdict, and a cryptographic signature — tamper-proof and independently verifiable.

sar-sdk provides the open-source foundation: sign, verify, and integrate receipts in any TypeScript environment.

The control plane builds above this primitive — centralizing policy, automating issuance across trust surfaces, and providing persistent verification.

Operating Model

Structured for centralized governance.

The operating model separates the control plane from trust surfaces — centralized policy and verification, distributed enforcement.

Hosted Control Plane

Centralized policy evaluation and verification, structured to run as a managed service.

Distributed Trust Surfaces

Enforcement at any boundary — browser, API, runtime, or pipeline. Trust surfaces connect to the control plane and enforce locally.

Centralized Policy Management

Define policies once, enforce everywhere. Updates propagate to all connected trust surfaces without redeployment.

Receipt Storage & Retrieval

Persistent, queryable audit trail for all attested actions. Supports compliance workflows, historical analysis, and dispute resolution.

Verification Services

Independent verification for any party. Validate receipts without trusting the executing agent or calling back to the issuer.

Product Hierarchy

Each layer builds on the one below — from open-source receipt primitives to the hosted control plane.
