Research direction

Start by locating the SessionDataSet.Next() implementation and tracing how it populates the Measurements collection. Reproduce the provided SELECT query, then compare the first record's measurements with the query result, focusing on the unexpected has_signal___int measurement. Done means Next() no longer adds measurements absent from the result and the behavior is covered by a regression check.

Written by the indexing model from the issue text.

Description

In the current version of the library, the Next() method behaves incorrectly. In certain cases, values are added to the Measurements collection that should not be included.

For example, when executing a SELECT * FROM root.raw.droot.test.test_device WHERE time >= 1773618600000 and time < 1773621600000 ORDER BY timequery, the first record contains the has_signal___int measurement, even though according to the query result, it should not be present.
