# Domain Modeling

Create and maintain a shared domain vocabulary and model that all code and tests reference.

## Process

1. **Extract terms** — What domain concepts appear in the conversation?
2. **Define precisely** — Each term gets a clear, unambiguous definition.
3. **Map relationships** — How do concepts relate to each other?
4. **Update CONTEXT.md** — Write the glossary where the agent can reference it.
5. **Align code** — Ensure code structure reflects the domain model.

## Rules

- Every domain concept gets exactly one name.
- Definitions are precise and unambiguous.
- The glossary is the source of truth for vocabulary.
- Code should use domain terms, not technical jargon.
