A position only becomes meaningful when its space and conventions are known. Follow these articles from general scene contracts into AR placement. Use a deliberately asymmetric test object, document transform directions, and separate import corrections from interaction logic. The practical goal is to make orientation and scale failures easy to reproduce rather than easy to hide.
