The wrapper surface previously widened every integer to i64. Wrappers now carry SQLite's own widths: i32 where the C API says int (result codes, counts, indexes, byte sizes), u32/u64 where it says unsigned (prepare flags, strlike escape, zeroblob64), i64 only for the genuinely 64-bit APIs (rowids, changes64, memory accounting, serialize sizes). sx converts implicitly in both directions, so call sites are unchanged.
