3 decimals is not a lot of precision for rotation matrices

I didn't do a comprehensive (or even remotely detailed) check on what kinds of precisions were in the lib.

We could potentially create an automated process to 'up-sample' matrix transforms that fit known angles (and possibly flag parts where the matrix transforms are 'random', as the odds of the part meshing are pretty slim and it's a weird use of matrices).

There's plenty of good reasons to have non-obvious matrix transformations, especially on rects abd other surface prims.

But certainly checking against floor and ceil (to various precision) on sin and cos 15n would be a good start.
