Initial Setter Difficulty: 1/5 (Potentially 2/5 if you are new to Nabners)
Normal Sudoku rules apply.
Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.
X-Sums (Diagonal)
Clues outside the grid are the sum of the first X cells in the corresponding diagonal, where X is the digit in the cell nearest to the clue. Digits may repeat within a sum.
Nabner Lines
Digits cannot repeat on a golden line, and lines cannot contain consecutive digits, regardless of order. An example of an invalid/broken line is '1374' as 3 and 4 are consecutive.
Special Thanks

Loved the variant X-Sums. Took me a moment to figure out how to count (5 is 5, not 4), but after that the puzzle was very smooth. Good setting :)

The unusual xsums constraint was way harder to tackle than the nabners. Around 1.5 difficulty. Great fun thx.

These fell into place quite nicely! I didn't expect these rules to fit together so well!

A lot of fun! I loved how for me nearly all the 4s fell into place like dominoes

Thank you for this nice puzzle, Flinty! The combo of Nabner and diagonal X-sums was great fun.
