## Description

Authority is an authorization framework for Ruby on Rails applications that manages user permissions and access control policies. It provides a system for encapsulating complex security logic into dedicated classes, separating these concerns from core business models.

The library enforces security rules by intercepting web requests at the controller level and validating actions against defined policies. It utilizes convention-based mapping to automatically associate models with their corresponding authorization classes, supporting both global checks and instance-aware validation for specific resources.

Beyond controller-level enforcement, the framework facilitates conditional interface rendering by allowing developers to check authorization status directly within view templates. It includes mechanisms for centralized exception handling, enabling consistent logging and custom error responses when unauthorized access attempts occur.
