Most of this makes sense. I think the main thing I'd suggest is
documenting the repair decisions being made and how things that get
zapped are then rebuilt - it seems like there is a lot of dependency
on running other parts of repair after zapping for things to be
rebuilt, but it's not immediately clear how the bits are supposed to
go together so a little bit of documentation for that would go a
long way....
