# Spatial Pattern Constraint Layer

A spatial pattern constraint layer turns *A Pattern Language* retrieval into concrete design moves and verification checks for agents.

The goal is not to ask an agent to “make a cozy city.” The goal is to retrieve patterns whose Problem/Solution framing can be converted into constraints the agent must satisfy.

## Formula

```text
intent → selected patterns → constraints → layout moves → verifier checklist
```

## Constraint Types

- **Scale:** region, neighborhood, street, building, room, detail.
- **Adjacency:** what should be near, visible, connected, or separated.
- **Gradient:** public/private, quiet/active, open/enclosed, light/dark.
- **Activity:** what people do there and why the space invites it.
- **Verification:** how to tell whether the design move actually satisfied the pattern.
