Architecture & Guides
This chapter collects deep-dive engineering guides, architectural invariants, and operational practices that govern software development across the Krewire ecosystem.
Whether you are contributing to core packages or authoring mission-critical applications on top of Krewire, these guides ensure your codebase remains maintainable, secure, and sustainable over long horizons.
What is in this Chapter?
Learn the spec-first engineering methodology: requirement numbering (KWL/KWN/KWM), traceability citations in Go tests, and automated quality gates.
Understand the four-rung open core ladder (free → pro → team → enterprise), strict module decoupling, and zero runtime lock-in guarantees.
Production deployment playbooks: multi-stage Docker builds, Nginx reverse proxy configuration, systemd daemon management, and zero-downtime rollouts.
