LG, just 1 question/nit.

It appears you ran an IDE reformat on these files without disabling a lot of very bad defaults. It's important to keep in mind that most IDEs do not, and often cannot, correctly format the codebase. The gradle spotlessApply task is much preferred.
Most of these comments are to not apply those reformats (particularly in Javadoc which is using a very resource-expensive, completely unnecessary, and relatively difficult to read formatting pattern).

Beyond that the Constants file should not have been removed (it holds exactly the constants we should be keeping and using from the Simulator).
