You wouldbe sleuths made it much harder...
...than it needed to be in the case of the larger of the 2 newlydiscovered primes.
If you had googled for Code:

Well sure, when you know exactly what to look for it all seems very easy.
Luckily for you guys the Google search engine wasn't interested enough to post here.

Anyone familiar with GIMPS knows what Res64 a new prime will have, and where it will appear. What's so "exact" about that, in the sense you seem to imply, i.e. that it requires insider knowledge?

No, I mean that since you knew that the report file has an all zero residue then if you search for it is easy to find. But I expect, that like me, other people here would not expect that the report file would ever have a zero residue posted and thus we would not have bothered to search for it.

I found your exposure of using a 4096K FFT enough of a giveaway
to predict ~42M and ~38M for the size of the primes.

Well, for all anyone knew, we could have had threadrelated problems at 2048K as well, forcing us to 4096K even for numbers < ~39M ... but yeah, once the ETC for the verify of the secondnumber verify was given, it was pretty obvious that the 2 primes would fall on either side of the 2048K FFTlength's exponent cutoff.
