Architectural Primers

Each primer describes a reference design, its trade-offs, and its typical evolution path. Build system-level literacy—the skill of recognizing architectural shapes and adapting effectively within them.

Planned Primers

• Big Ball of Mud — Unstructured, emergent architecture and how to work within it
• Three-Layer — Presentation–Business–Data separation patterns
• Ports and Adapters — Hexagonal architecture and boundary management
• Access Control Layer / Gateway — Controlled entry points and security patterns
• CQRS — Split read/write models for scalability
• Event-Based — Asynchronous communication patterns
• Service-Oriented — Modular systems by capability
• Domain Split — Autonomous systems per domain
• Domain-Specific Language Design — Using language as a modeling tool
