Your sorting effort 

Wow! This will raise the number of assessed articles substantially. Do I understand the process correctly, that once tagging is done, a bot will generate overview and stats pages.

One minor caveat: Award articles, like Wigner medal, all seem to get the "stub" category, per "auto", allegedly because of a stub template. But:
 To the best of my knowledge those articles never had a stub template
 IMHO there is no big potential for expansion, either they
 should be considered list-like and excempt from article assessment
 be rated somewhat like "short, but no need to grow"  a seemingly missing assessment grade

Only a nitpick in the grand scheme, but I'm just watching a number of those articles, so I was wondering.
