OK, mea culpa, maybe I misunderstood the apparatus and it was not the CC
that records
things, but still the records
could be kept somewhere, and one can ask what would happen if the records
were
kept somewhere else (e.g. in a macroscopic medium).  No?

Yes but we are choosing which half to throw out in a very peculiar way --
i.e. we are throwing it out by "un-happening" it after it happened,
by destroying some records that were only gathered after the events
recorded in the data already happened...
