- [x] Unit tests for rootcoord drop field/function logic
- [x] Unit tests for proxy task validation (drop field constraints)
- [x] Unit tests for datacoord index service (dropped field handling)
- [x] Unit tests for querynode segment loader (dropped field skipping)
- [x] C++ unit tests for SegmentLoadInfo ComputeDiff with dropped fields
