## Description

This project is a reactive state management library designed for Angular applications. It provides a centralized store that maintains a single immutable source of truth, ensuring that all application data transitions follow a predictable, unidirectional flow.

The library implements the Redux pattern, utilizing discrete actions and pure functions to trigger state updates. It leverages observable streams to propagate these changes, allowing user interface components to bind reactively to specific slices of data. By isolating asynchronous operations and external interactions into independent action-driven streams, the framework keeps core business logic decoupled from side effects.

Beyond state handling, the system includes comprehensive instrumentation for debugging and inspection. Developers can record sequences of actions and state snapshots to replay, pause, or revert application history. The library also supports synchronization between the centralized store and browser navigation events to maintain consistency across the application.
