The demo seed parity case, the transaction yield probe and the test UnitOfWork check read their row counts and rows back with raw statements; they now use the ORM readers. The statements these files are about stay raw and are marked: the dirty read and write the transaction yield probe measures on the shared handle, and the reset-admin.js case, whose database file has no ORM bound to it.
