// argument to an injected `rowSchema` in the OPTIONS object (arg 1, not arg 0).
// Cell<T> Row fields become asCell, keyed by the Row field name — so an aliased
// link column (SELECT author_cf_link AS author) is detected with no _cf_link
// suffix, exactly like the free-function sqliteQuery<Row> form.
