These fragments can be of any length.

1) Yes
2) In the example, cards 3 and 5 share a common diamond.

Puzzle 8 : the 1-2-3-4-5 bottom clue line doesn't go til the upper left end (it stops 2 cells before). Is this normal or a display error ?

In puzzle 2, a table displays some letters and their values. Is this an illustration or a real mapping? As I see it, it does appear to be illustrative as many of the slots don't have words that satisfy 1 = A ,P, R. I have no way to know unless I understand the rules well. There is no example either

Streets of 1x1 are allowed?
Is this a town puzzle with 2x2 white areas not permissible? Or the white strips must be 1XN when evaliating the score? There is no clear demarcation in the description between puzzle rules and score evaluation.

In puzzle 2, the mapping of 1 - A,P,R given doesn't seem to fit the grid. Is it applicable to the grid or given as an example?

I think the given letters are part of the puzzle, not just an example. Remember that not every name is going to be used.

Not every name is used, but every slot needs to be filled in. There seem to be no names from the list matching the slots.

Puzzle 9 : what does "passing through all rows and columns" mean for the loop ? In the example, the loop doesn't use the top line of the grid at all...

Thanks, for some reason I was thinking consecutive letters should be the same if the numbers in the cells are equal.

Puzzle 11: "...it is possible to uniquely restore their contours." Does the assignment of numbers to cards have to be unique, or is it enough to uniquely specify the nine 3x5 borders of the cards?

In puzzle 10, I am nut sure whether I can consider a solution as valid if it is the only way of respecting the rules and the clues. Can Riad (or any of the organizers) check the solution I have currently filed and tell me if it is valid and unique?

The reviewer should clearly define the borders of the nine cards and their numerical values.

I was sent your solution, it is not valid. Some rectangles that you were supposed to declare dark can be declared completely white. You need to get a solution without 2x2 white fragments. You use this condition as given in advance. This is incorrect.

Puzzle 7.
For numbers with cells, the use of rules a) OR b) is true. If there is a cell where the rules are applied a) AND b) is this true or is it wrong?

In the town puzzle mini example, going by the definition of a street being a stretch of white cells of length 2 and width 1, I can make out 6 streets in the solution for it. But the answer key gives it as 4, so have i understood it wrong?Or is there a mistake in the example's key?

Someone kindly rephrase that answer, as I cannot understand any of it. I have already submitted a solution and I am pretty sure I understand what is expected. But, this new piece of information makes me believe that I may still be missing something though it is very unlikely. Organizers, either confirm that my solution follows the rules, or please confirm what is mentioned in that last reply by the author.
A slightly larger example grid might clear any doubts ( "You use this condition as given in advance" - he meant 'used' OR 'need to use'). The language seems to be the source of all confusion here. Reviewers have to step up their efforts.
