- guest_uses_shift_operations: i32.shl and i32.shr_u bit shifts
- guest_uses_bitwise_and_or: i32.and (0xFF & 0x0F) and i32.or (0xF0 | 0x0F)
- echo_and_double_coexist_same_worker: different guest types on same runtime
- guest_reads_i16_from_payload: i32.load16_u reads little-endian 16-bit value
All 224 tests pass. No new bugs found.
