## Description

This project is a set of software engineering standards and architectural patterns for writing maintainable and refactorable TypeScript code. It provides a comprehensive guide for implementing clean code principles, focusing on the application of SOLID design and structural patterns to build decoupled systems.

The framework prioritizes composition over inheritance and utilizes dependency inversion to reduce system coupling. It establishes standards for strict static typing and the use of read-only modifiers to ensure type safety and eliminate runtime errors.

The guidance covers a broad range of capabilities, including project organization through standardized source file layouts and path aliases, function design based on single responsibility, and the management of immutable state. It also defines patterns for asynchronous logic management and the creation of independent, repeatable unit tests.
