Should be applying an offset to LAZ data, it's currently 0 which will lead to unnecessary errors for high-precision/high-XYZ-magnitude data. Offsetting to the center of the dataset bounds would be ideal.

[untwine] Fix precision issues when indexing
2d8431b 
Offset and scale of X/Y/Z dimensions were not written and
some datasets would simply fail to get indexed completely.
Other datasets may have had the data slightly misaligned
after indexing.
