"""RAID — Research Architecture for Intraday Data (UQO Working Paper No. 40).

Python layer: the compiled extension ``raid._core`` (nanobind) exposes the C++20 estimators and backends;
``raid.findata`` is the FinData OS client (bars, exports, provenance); ``raid.api`` wraps the extension with
NumPy/Arrow-friendly signatures and the ``backend="auto|cpu|metal"`` choice.
