So Calvinball kindly asked for more mirror puzzles...
- Normal sudoku rules apply.
- Modulo 3 Mirror: Each cell has a digit in the same residue class modulo 3 as the cell reflected along the marked diagonal (e.g. if r2c6 is in the [258] class, r6c2 is also in the [258] class).
- A clue outside the grid is the sum of the first X cells in the corresponding row/column, where X is the digit in the cell nearest to the clue.

Solution code: Column 5, top to bottom.

That was a really fun solve. The combination of restrictions here led to some really novel tricks that I enjoyed working out!
