Configuration Is Not Secondary. It Is the System.

Configuration Is Not Secondary. It Is the System.

Short summary

Configuration should define system behavior—not just tweak settings—with code serving as the execution engine. This architectural approach promotes clarity by centralizing behavioral definitions in configuration rather than scattering logic across code, and enables systems to become self-documenting and consistent. When configuration is treated as the source of truth, systems become visible, maintainable, and scalable without requiring developers to reverse-engineer behavior from implementation details.

  • Configuration as source of truth makes systems visible and self-documenting
  • Code becomes the execution engine, not the logic holder
  • Reduces pattern drift and enables consistent, scalable architectures
