It's easy to read something and repeat it back - but if that's it, I want the original source of info to check for myself - I don't want an intermediary.

This is the actual scientific article:

Sorry, after 2.5 years I misremembered pg/mL as fg/mL but its all too small to matter.

You don't need circulating spike to explain vaccine caused myocarditis. The vaccine produces an immune response. The initial immune response are low affinity antibodies. Those antibodies can sometimes target host cells accidentally. As somatic hypermutation happens in the months following the exposure to the antigen the high affinity antibodies that form (and which are boosted by a 2nd exposure to the antigen) are less likely to accidentally target host cells. This is presumably why I had a complete recovery after around 2 months and all I needed was an NSAID to tamp down the inflammation.
The obvious objection to that article is that correlation is not causation. It needs to be replicated, and there needs to be more than just speculation about a mechanism. There already exists a very well-known mechanism (autoimmunity) for the alternative explanation.
I am taking your comment to mean that you think it's not a credible paper? That's the main thing I wanted to know, it seems like you believe the paper implies something very unlikely and so authors have an agenda?
Vaccines don't cause circulating S protein at any levels that could cause damage to organs.
We can measure some S in the blood after vaccination, but it is at levels of femtograms per milliliter. Spike is confined within the cells that the vaccine enters and isn't sprayed around the circulatory system by the vaccine. What is displayed on the surface of those cells is the T-cell epitopes after the protein has been chopped up by proteases and those relatively short sequences are displayed on MHC for the immune system. The spike that leaks out is probably only due to those cells being lysed in the lymph nodes.
That is many orders of magnitude less of an exposure than someone who is infected and has literally billions of virus particles floating around expressing spike on their surface.
The vaccine won't cause any effects via circulating spike, that is just bullshit that was being spread early in the vaccine rollout. The reactions to the vaccine are going to be autoimmune-mediated.
