Greg Egan is famous for examining various other variations of this physics.

e.g. Dichronauts examines the 2+2D case which turns out to be very different from 4D or 3+1D.

The issue isn't string theory yes or no (there are reasons physicists went this way and other alternatives aren't so much better), but the difficulty in getting data and testable predictions. It's very likely the most effective way to help particle physics is getting way more data at high energies, not a new theory.

The prediction is just 105 orders of magnitude (and an extra dimension) away, but ok.

Only about 2 orders of orders of magnitude - not bad for string theory.

Compare to Havana syndrome - another disputed 'mystery brain disease'.

CHUPPL did a deep dive on this one I highly recommend https://www.youtube.com/watch?v=xqE0ltifQ2M

functional disorders like ME, CFS, Havana syndrome, chronic lyme are very common, particularly since the emergence of patient communities enabled by the internet.

That's outside this threat model? The idea here is trying to foil outside analysis, not limit the document authors (which are allowed to add/update and even write openly 'the intended recipient's identity').

e.g. post-WW1 Turkey following the Armenian genocide.

Obvious problem is anticircumvention laws are just as much an interest of the EU and others. These laws pass power from the individual, and the EU (its corps and govs) are just as interested in exercising power over the individual.

Oh dear, time to switch to OpenVMS on Itanium arch.

Note most modern Chess engines use UCI instead of Winboard protocol. But either is fine really.
