Platform

Architecture

High-level system architecture of Syzygy Rosetta — how applications, governance middleware, AI models, and compliance systems interact.

System Architecture Overview

Applications
Loan origination systems, fraud detection platforms, AML monitoring tools, underwriting engines
Rosetta — Governance Middleware Layer
Policy evaluation engine, risk assessment service, evidence generation, receipt management
AI Models & Data
Decision models, risk engines, ML pipelines, data sources, third-party AI services
Evidence Store
Tamper-evident receipt storage, cryptographic sealing, chain management

Stakeholders & Consumers

The architecture serves multiple stakeholders who interact with Rosetta in different ways.

Compliance Teams

Review audit receipts, verify policy compliance, respond to regulatory inquiries.

Risk Teams

Monitor risk patterns, identify model drift, assess governance effectiveness.

Internal Audit

Independently verify decision documentation and control effectiveness.

Regulators

Examine evidence records during examinations and investigations.

Engineering

Integrate applications with Rosetta, configure policies, manage models.

Business Teams

Access decision analytics, review workflow outcomes, manage exceptions.

System Boundaries

Rosetta is designed as a middleware layer that integrates with existing systems rather than replacing them. It operates at the governance boundary between:

  • Applications that initiate AI-assisted decisions and Rosetta's evaluation engine.
  • Rosetta and the AI models it governs (model outputs are evaluated, not modified).
  • Rosetta and the evidence store where audit receipts are preserved.
  • Rosetta and external audit/compliance systems that consume evidence records.
Architecture Status

The architecture described here represents our current design vision. Specific components, interfaces, and deployment patterns will be refined during development. We do not claim production-ready architecture at this stage. Implementation details may evolve significantly as we progress toward Rosetta v1.

Design Philosophy

Separation of Concerns

Governance logic is separated from application and model logic, enabling independent evolution.

Integration-Friendly

Rosetta integrates via standard interfaces and protocols, minimizing integration effort.

Evidence-First

Every component is designed to produce and preserve evidence as a primary function.

Scalable by Design

Architecture supports horizontal scaling for high-volume financial workflows.
