+
+### Added
+- Implement `TableProvider::statistics()` on `DuckLakeTable`, populating `total_byte_size` from per-file metadata cached on the table (#112). Mirrors DuckLake's `ducklake_table_info` aggregate exactly. Marked `Precision::Inexact` since the catalog tracks compressed parquet bytes while DataFusion documents `total_byte_size` as uncompressed Arrow output. Enables cost-based optimisation hints and provides a cheap surface for size-aware consumers (e.g. pre-flight ingest guards).
