In a standard sudoku grid, the boxes are numbered by convention from left to right and top to bottom such that the top left box is box 1, top middle is box 2, and so on. Within each box, the cells are numbered the same way.
In this puzzle, the boxes have been separated and shuffled around, and it is up to the solver to determine their actual placement in the solution. Each box must have its box number in that position within the box (i.e. box 1 has 1 in position 1, box 2 has 2 in position 2, etc). No other digit in any box may be in its self-numbered cell.
Fill each box with the digits 1-9 so that when the boxes are restored to their proper positions, each digit appears exactly once in each box, resulting row, and resulting column.
Digits in a cage must sum to the indicated number.
Clues outside a box with no arrow are X-Sum clues: the first X cells, where X is the first seen digit, sum to the value of the clue. ? sums must be deduced by the solver. Sums do not cross box gaps.
Clues with an arrow are Little Killer clues: digits along each indicated diagonal sum to the value of the clue. Diagonals do not cross box gaps.

Great fun ! Solved it using my own upgraded grid of the puzzle, with a blank sudoku grid besides the twisted one. Thanks for this beauty :)

Yet another mad puzzle from a mad genius.

Could you clarify what "X-Sums do not cross box gaps" means?
---
The boxes are separated, which means they have gaps between them. X-Sums cannot be longer than the distance to the first gap.

Very novel, the setting of the puzzle is also very good!
Btw, this may be a late reminder: When you are solving this puzzle, it is best to prepare a blank grid, and fill in the already determined boxes and the numbers in them.

Beautiful variation. Used an empty CTC grid to put the blocks in right place. Hope to see more of this kind.

Amazing puzzle! There's a lot of very neat and well telegraphed logic to figure out, I enjoyed it a lot. Opening a second penpa page was very helpful to keep track of the progression. Thank you!

Very nice and very hard. Had to open a grid in f-puzzles and place the boxes there when I solved it.
