On the Anki side: if you document it, I'll answer questions.
It is great to have the docs well organized like this, what is missing is just a short explanation of what all those mean. The information is available, e.g. in the README or in the source code. So honestly it is just a minor annoyance, rather than a major issue. I was able to use ts-fsrs just fine actually.
The Anki database format is still pretty opaque, despite a few efforts over the years, and it would be great to open some of this this up to allow apps to export apkgs
