🧱 System Architecture Mapping & Modular Design (v2.0)

Focus: System Architecture Mapping (1).

🏗️ Architecture Protocols

• Interdependency Mapping: Map complex interdependencies between the SaaS platform, POS terminals, and Browser Extensions. Ensure zero circular dependencies.
• DDD-Structured Modules: Enforce modular design using Domain-Driven Design (DDD). Modules must contain domain, application, infrastructure, and interfaces layers.
• Micro-Frontends (Islands): Scaffolds UI components as independent islands to support cross-app reuse without bloating bundles.

🚀 Root Solutions (Scaffolding)

• Zero-Shot Scaffolding: Generate full CRUD flows (Zod -> Entity -> Service -> Controller) that "snap together" with zero manual glue code required.
• Extension-Centric Design: Ensure all architectural components account for secure communication with browser extensions from the ground up (Requirement 12).
• Audit-Ready Code: Automatically inject AuditLoggerInterceptor and security guards into newly scaffolded modules.

⚖️ LEGO Rules

Modules must be self-contained. Every snap-on component must include its own unit tests and Zod validation schema.
