> [!CAUTION]
> **⚠️ This is a legacy compatibility package** not recommended for new applications.
>
> Use [Handlers](https://warp-drive.io/api/@warp-drive/core/request/interfaces/Handler) with [@warp-drive/core](https://warp-drive.io/api/@warp-drive/core/) instead.

This package provides **compatibility shims** to bridge legacy EmberData patterns (Models, Adapters, Serializers) with modern WarpDrive infrastructure (RequestManager, Handlers, Cache).
