you may want to attach a hip file with your test geo to see it in broken state, since testing on grid it seems to work fine and groups seem correct apart from it messing up the incoming "corner_to_be" which the code doesn't attempt to correct

also it seems to be written for Detail wrangle but processes each prim independently so you can simplify it for prim wrangle and remove your prim loop as well as split_prims checks as each prim is processed just once regardless

not necessarily for a specific button, but there is a shortcut to do the same thing in the viewport if you press ` (left of 1)
it's in the Select menu called Reselect For Current Tool

- Is there a builtin way to do that? Just map to primvars would work great

I don't think there is on LOP side since usd primvars don't have equivalent type of dict attribs and even when expanding to primvar per key there would probably be ambiguities in terms of nested dicts or name collisions with existing attribs etc.

however in SOPs you can add Attribute Adjust Dictionary set name to your dict attrib and enable Export Attributes: *
that will extract the keys as attributes

you can make a wrapper around SOP Import for this or set it up inside of SOP Create where you bring your data as Object Merge and then extract dict attribs
