So if such a document is produced then that would prove that you
are wrong. Would you bet your life that you are right andsuch a
document could not exist, orif not your life would you bet your
house? Or would you be more conservative like me and just bet a
week's salary? I think such a document could exist,

If the experiment is performed many times and the results are
always the same are you proposing there is some universal law that
requires the universe always be lying to us? It's sort of reminds
me of the Bible thumpers who say God planted dinosaur bones in the
Earth just 6000 years ago to test our faith.
I think you need to do some research on delayed choice and quantum
erasure experiments. These experiments have been done and are
essentially equivalent to Deutsch's thought experiment.
The only difference is Deutsch attaches a printer that keeps printing "I
saw which slit that one went thru."

There is no mystery in interpreting these experiments. In all cases,
if the which-way information is preserved, no interference is seen.
But if the which-way information is quantum erased, interference is
visible. How this works in the delayed choice set-up has been
explained by Sabine Hossenfelder.
