+"""tac-qlib: read the TradeAC parquet lake from within the qlib research workflow.
+
+This package is fully decoupled from the upstream ``qlib`` checkout. It provides:
+
+- ``tac_qlib.qlib_init.qlib_init``: drop-in ``qlib.init`` configured against the lake.
+- ``tac_qlib.data.providers``: qlib data providers (calendar / instruments / features)
+  backed by the lake parquet files, so ``qlib.init`` + ``D.features`` work without any
+  ``*.bin`` data.
+- ``tac_qlib.contrib.data.handler``: a ``DataHandlerLP`` subclass (``TACHandler``) that
+  builds a train/test dataset from raw OHLCV + pre-computed ta-lib features.
+
+Upstream ``qlib/`` is never modified.
