Sounds like the immortal jellyfish solution. We squeeze entropy out of our DNA by creating a new fresh cell (ovum) that’s very sensitive to genetic defects, meaning if it survives it’s probably good. The jellyfish just shrinks back to a single cell (presumably with some mechanism for keeping the ‘best’ cell) to reset the damage. This is doing the same thing, but piece by piece.

Edit: And wow, that abstract appears to have eaten an entire thesaurus.
