8.1 negative samurai. the samurai consists of five different sudoku variants that overlap each other with exactly one 9x9 block .....or perhaps one 3x3 block? is there anything mysterious about this samurai or is it just a typo?

That's a silly (and funny! ) typo. Will be fixed.

8.2 Clueless Hidden Classic

Would we be allowed to bring a blank grid to assist with solving the hidden puzzle? (Or will one be provided, even?)

Blank grids are not on the list of permitted items.

You may bring blank sheets of paper, though.

And of course only digits written on the official competition puzzle are taken into account.

regarding the consecutive circles sudoku. I believe that the rule is "digits on EACH grey circle are all different",in fact there are two circles with the same digits 6789.

I also notice that all possible sets of digits are used (1234,2345,3456 etc.) with one set used twice. Is there any requirement in this respect or is it just a coincidence?

Also. are all the possible circles marked?

That will be coincidence.

Not all possible circles are marked. In that case it would have been in the instructions.
