test_ohlcv_fixtures
===================

.. py:module:: test_ohlcv_fixtures

.. autoapi-nested-parse::

   Polars-free validation of the OHLCV golden fixtures.

   Recomputes bars from the prepared-trades fixture with pure Python and compares
   against the exported bars, so hardware-facing tests can rely on these files
   without a polars dependency. Fixtures are generated by
   ``python -m dau_polars.ohlcv_fixtures`` (see dau-docs-private/OHLCV_BARS.md).
