How about we switch to ecc, which would help with bit rot not sector

Interesting aspect.

Yes, we can implement ECC as a special crypto transform that inflates
data. As I mentioned earlier, it is possible via translation of key
offsets with scale factor > 1.

Of course, it is better then nothing, but anyway meta-data remains
ecc-unprotected, and, hence, robustness is not increased..

Would you prefer to do it as a node layout plugin instead, so as to get
the metadata?


Yes, it looks like a business of node plugin, but AFAIK, you
objected against such checks: currently only bitmap nodes have
a protection (checksum); supporting ecc-signatures is more
space/cpu expensive.
