This has all the elements of a good problem. Interesting play (switchbacks, bristol & selfpin) with a quiet end and a mid-board model!
But one solution!
I think that there is not enough meat for a single solution.
I have a feeling that it is possible to have most of the contents (probably, not all of it) in two solutions, adding to the pile second echo mate and some change of functions.
As always, I’ll check this feeling.
I confirm it is possible to have two analogous phases.
I have reasonable working position, but still want to improve it.
Due to serious technical difficulties and extreme time needed to computer test the problem, I disclose current position.

I am not happy with twins and with motivation for the third black move. Unfortunately, most possible “normal” black moves allow interchange of the third and forth moves – and this is the reason for “crude” twins, which destroy the uniformity of A/B. Still there are some possibilities, but they seem to require extra black material and because of it are extremely prone to cooks (and need even more time for computer test).
Nice try, Georgy! I suppose your problem is a completely independent work that needs no remark “After X”.
Though the construction seems to heavy for hs# genre, the usage of black and white force is excellent, in my opinion.
I refer to the article by IGM P. Petkov in which he had proposed several aesthetic criteria. In particular, he wrote :“The economy of material in this genre is so important, that usually a composer must strive to express his idea with less than 15-16 pieces, using 17 or more pieces in some exceptional cases.”
Here is the link to the article – https://juliasfairies.com/pap-hs-its-very-interesting/
I too think that Georgy’s problem is different in content despite some similar motifs like white selfpin-shutoffs and quiet mates.
Here is the diagram:

Thanks for kind words.
Vitaly,
As this position would have never existed without 1082, it may only be published as joint problem, if you agree.
It seems that two solutions form is unreachable – adding black piece immediately leads to innumerable cooks.
I am currently trying to have a twin of the following kind:
b) f7 > g7
In this case the problem will have ABCD-CDAB instead of simple AB-BA. I have a working version, but each of two white knights is only needed in one phase. The problem would probably have been correct with extra Q or B. Still, not all possibilities are exhausted.
Georgy,
I’ll be happy to see your reworking of my hs#5 published as a joint problem.
ABCD-CDAB would be fantastic, if succeeded!
To reach the correctness maybe we should try to enable some fairy condition, what do you think?
