Thank you for this example. So I cannot assume inode
numbers to be in a specific order. It will force me to
do what I originally intended to do: Iterate from 2 up
to the maximal number and then check the availability,
and, if given, "trace back" the ".. chain" to an existing
directory entry point - or re-create one, if it is missing,
too. Will be a lot of work, but I think I can learn much
from this.

Remember, kids: Learning is fun. :-)
