The prisoner concludes that the hanging can’t be on a monday; the chart is missing U6 with all Is.
One of the things that might confuse around this is that one can try to read it as “we will hang you if we find a surprise day to do so” or as “we will hang you and from this sentence you can not deduce when”. The hanging not happening is consistent with the former but not consistent with the latter.
I think the core of the paradox is preserved if the sentence would rather be “we will hang you tomorrow and it will be a surprise for you”. “Proof” of expecting it relies on the sentence, yet the sentence is not false.

Thanks for your suggestion. I just added U6 to the chart.
