Houdini default instancing matches the geometry index to the point index, while it appears Solaris instancer, at least by default just looks at the total list of input geo. I need the instancers to match by index attribute regardless of the total index amount.

Any tips on how I can correct this?

Here's a much simpler example. In SOPS if I change the variant index number of geo it will find the corresponding source point variant number. Not so in LOPS. I suspect I'm not importing the variant attribute correctly into LOPS

Hi Andrew, unfortunately despite its similar-looking/-sounding names, the "Index Attribute" mode on the Instancer LOP is (as you've discovered) *not* the same as in SOPs. There is an existing RFE to do similar matching (RFE112244).

The workaround for now is to use Name Attribute.
