Wow, that article has a huge list of "data exfiltration channels" that are possible attack vectors.
This is an interesting problem, and I hope that I'm somehow able to trust again.

Proximity seems to be key to most of these attacks, so maybe physically excluding any possible eavesdroppers, and adding noise sources would create a shell equivalent to guarding that piece of paper.
I also anticipate gathering old/very limited electronics that can be visually inspected or don't have extra capacity to run malicious code to allow auditing the mechanisms of computation.
