Overview

Package specification implements Specification tactical pattern. Validations are implemented as separate structs, each sharing a common interface that defines a single function. This allows us to utilize multiple, reusable validation rules independently. The `validUsers()` function remains unchanged while supporting different validation logic, leveraging polymorphism via injected specification dependencies. This approach adheres to the Open/Closed Principle — allowing behavior extension without modifying the existing code.
