Research direction

Start by reproducing the aggregation-plus-interpolation query described for IoTDB 0.12.5 and compare results before and after August 8. The issue does not include the query, dataset, or named source files, so gather those details first; done means interpolation results after that date are no longer identical when the underlying data differs.
