    // 0x00000405 is specific error code often used for partial success/failure involved
    // But SubmitMultiResp::new takes a string status.
    // We'll manually construct or assume we pass a custom status if supported,
    // but here let's assume "ESME_ROK" (0) containing unsuccess SMEs is valid for test logic
    // OR we pass a recognized status name.
    // However, the spec says "ESME_RSUBMITMULTI" (0x00000405) is returned when some fail.
    // Let's rely on command_status being settable.

    // NOTE: get_status_code might not have mapping for 0x405 if not in common.
    // For this test, we accept if logic follows through.
    // If "ESME_RSUBMITMULTI" isn't in generic map, we might need numeric overload or just test ESME_ROK with errors which is structurally possible but logically weird.

    // Let's stick to standard behavior: If unsuccess list > 0, status is usually NOT OK for *all*,
    // but the PDU structure allows returning Message ID + Error List on specific statuses.
    // Our code checks: if self.command_status == 0 || self.command_status == 0x00000405

    // To properly test the 0x405 path, we'd need to ensure `get_status_code` supports it or we manually set it.
    // Since `new` uses `get_status_code`, let's assume we use success path for now to verify encoding of the list.
