- SEA inline JSON: fetchall() rebuilds per-column facts once per row, and a decimal Context once per cell0

- _convert_arrow_table's default path spends 45% of itself building a 2-D object buffer it does not need

0 - Arrow results with duplicate column names still raise ArrowInvalid when they span more than one chunk

1 - concat_table_chunks rebuilds the table when there is only one chunk (40% of a columnar fetchone)

1 - No CI on this forge: seven releases have rested on a local pytest run

1 - Negative result: _create_rows is 81% of an arrow fetchall() and cannot be made faster without a behaviour change
