A layman question:

If Faraday cage holes are smaller than the gamma ray wavelength, does it protect against gamma rays? Or is a thick lead wall needed for M-Disc protection? Is it even possible to construct such small cage holes?

gamma rays = electromagnetic waves

Preserving an M-Disc against a nuclear blast seems futile, as the high temperatures can turn even stone into dust. Is there even a practical way to engineer survival in a nuclear blast? (Any physicists? Engineers?)

Here's a guide on making a Faraday cage, but can it also protect against gamma rays?

>does it protect against gamma rays

Probably not. Might need to throw in some lead, concrete and water barriers.

I wrote my answer as pretty tongue in cheek. It gets to a stage where certain threats being solved for would wipe out humanity anyway, which is why my last suggestion is summarising the lessons of your data into stories and parables to be passed on from generation to generation :)
