A full proof of its nonhalting by chxu can be found here: https://chrisxudoesmath.com/papers/skelet17.pdf
Adapting the above, a formal proof of its nonhalting by mxdys can be found here: https://github.com/ccz181078/Coq-BB5/blob/main/Skelet17.md
There was also an analysis by savask: https://docs.bbchallenge.org/other/skelet17_savasks_analysis.pdf
