Technical & Architecture Concepts

Welcome to the technical conceptual guide for this project template. This section is designed to explain the software engineering foundations, package management, developer workflow tools, and architecture principles that govern this repository.

This project is built as a hardened, production-ready foundation designed for modularity, clean vertical slice separation, strict developer quality gates, and AI-assisted development.

Core Technical Chapters

In this section, you will learn about:

  1. Vertical Slice Architecture: How we structure our codebase around cohesive features and business use-cases instead of traditional technical layers.
  2. Pixi Package Management: Why we use Pixi for fast, deterministic, cross-platform dependency management and multi-language toolchains.
  3. Open Knowledge Format (OKF): How we structure repository documentation to serve as a machine-readable knowledge base.
  4. Linting & Type Safety (Ruff & Mypy): How we use modern, high-performance static analysis tools to maintain a bug-free code environment.
  5. Data Validation (Pydantic): How we enforce robust runtime type checking, schema parsing, and configuration validation.
  6. Architecture Transition: The rationale and design of transitioning from a decoupled FastAPI/Streamlit microservice model to a consolidated monolithic Streamlit runtime.
