Identity & permissions
Authenticate the user and authorise each retrieval or action. Keep permissions attached to the information.
Architecture / Interactive guide
Understand the system.
One layer at a time.
Explore the role of each layer, the decisions within it and the connections that make it useful. This is a conceptual model, not a deployment blueprint.
03 / INTELLIGENCE
The AI layer
Models use context and tools within the boundaries set by the system.
What matters here
- Choose the model for the task
- Evaluate the quality of its responses
- Control tool access and consequential actions
Depends on relevant data. Supports the application.

through every layer.
Security, evaluation and oversight belong throughout the system, not in a box added at the end.
Evidence & evaluation
Measure retrieval and answer quality separately. A fluent response is not proof that it is correct.
Operations & oversight
Monitor quality, cost and failure. Give people control over consequential actions and a route to recover.
