Abstract
The architecture update adds a platform view and an authorized request-to-action path, with an invoice example connecting domain ownership, context, retrieval, approval and execution.
A practical architecture for domain delivery, shared services and consistent enterprise control. Domains publish supported products; shared infrastructure and a common control plane make their operation coherent.
The paper connects analytical and operational paths, sets out the three platform planes, explains where a semantic layer helps and where it does not, gives selection criteria, shows the control plane in action, and treats copy-or-query as a cost and control decision. It closes with golden paths, a capability map, AI services, agent access and a readiness sequence.
It assumes the stack you already have. In a smaller firm the platform can be one managed cloud stack and a small team; the sequence holds, and each step is smaller.

From domain data to an authorized AI action.
Domains own their products and meaning. Shared services support identity, policy, delivery and operation across analytical, operational and knowledge paths. Each serving interface enforces the decisions that apply to its resources.
A question and a command have different authority.
An employee asks why an invoice is held. The application verifies identity and context, then retrieves permitted evidence. A request to change the invoice follows a separate approval and command path. The model’s response cannot grant permission.
This is a reference design for client architecture work. It does not describe every capability of the current Studio demos.
In the paper
Three passages, as published
Architecture is not authorization
Name the policy authority and each serving enforcement point.
Count all operating cost
Zero-copy isn’t zero-cost, and it isn’t automatically safer.
The platform promise
A team can create a supported product without rebuilding identity, deployment, monitoring and baseline policy from scratch.
