As we discussed and decided in discord it's OK to keep the repo private until the end of the contest.

Another way to look at results -- by medal count. Border is part 1 (doesn't count), background is part 2.

OK. The first time I followed to the end. 
The code I was forced to produce by time pressure is so ugly and dirty that I refuse to publish it.
Nevertheless a  clear demonstration for what was ISOS (aka COS) NOT designed for:
Higher mathematical calculus, matrix transformations, arrays with independent dimensions, ....
[ Though I have to admit that I encountered tensors, rotors, matrix transformations, Mr. Fermat's theories, ... only at university 50+ years ago. And I didn't miss it in between angel]

There was no demand for the real strengths of IRIS!
In addition, I verified my personal credo that writing some code in ISOS/COS
only because it is possible makes no sense and is of no commercial value.
Especially with the broad range of options in  IRIS to include external code.
