Dear Jarek
Congratulations for your essay - I am proud that I alerted you to this fqxi contest. While I only understand it qualitatively, I can see that you have excellent grasp of your ideas and have presented them consistently in the text, and beautifully in the illustrations.
As I mentioned in our previous discussions, I agree with your idea about a particle as a soliton pushing its surrounding wave field ahead of it. Within such particles and around them there is an exquisite order due to rotation of spin axis as you have shown in your Figure 4. While your treatment concentrates on particles and is on a very sophisticated theoretical level, I have described such a way of thinking (classical spinning magnetic-like nodes creating topological fields; a particle passing from one slit while its field goes through both slits; the neutrino as a soliton discontinuity in the field, etc.) in my qualitative 2005 Beautiful Universe Theory upon which I based my fqxi essay Fix Physics! .
I cannot prove it or show it in detail, but I feel that your concepts reflect an even deeper order in Nature, causal and linear at the tiniest levelsand in the vacuum itself. "Random vacuum fluctuations and virtual particles" may one day disappear from the lexicon of physics to be replaced by the sort of simple realistic mechanical and topological effects we both describe in different ways.
By the way your kaon/hyperon twisted loop of Fig. 6 resembles the shape of the electron orbits in Kenneth Snelson's fqxi essay. Perhaps you can kindly comment on his idea - he is a famous sculptor and the inventor of tensegrity (balance through compression/tension in a configuration), and has interesting ideas about atomic structure. He is 85 and has had little encouragement from mainstream quantum theorists.
Finally please allow me to attach a figure showing a test I proposed for the idea that the electron 'pushes' its field in the double slit experiment as in Couder's video. If the double slits are each smaller than the particle in size so that it cannot pass, yet interference of its wave field still occurs because the wave-field can pass through.
I wish you all success.
