System Design Architecture Standards

Priority: P0 (FOUNDATIONAL)

Architectural Principles

• SoC: Divide into distinct sections per concern.
• SSOT: One source, reference elsewhere.
• Fail Fast: Fail visibly when errors occur.
• Graceful Degradation: Core functional even if secondary fails.

Modularity & Coupling

• High Cohesion: Related functionality in one module.
• Loose Coupling: Use interfaces for communication.
• DI: Inject dependencies, don't hardcode.

Common Patterns

• Layered: Presentation → Logic → Data.
• Event-Driven: Async communication between decoupled components.
