Interference Pattern
(Published on 17. January 2023, 11:50 by Jeet Sampat)
Many thanks to @Leonard Hal for correcting the previous version. I totally missed one small problem with the final leg of the puzzle. I am sorry for those who tried the previous version and got stuck.
Rules:
Normal Sudoku rules apply.
Shade some rows blue and some columns green.
The number in the top-left corner of a cage gives the sum of blue digits minus the sum of green digits within the cage.
Cells that are both blue and green do not contribute to the cage sum.
Digits cannot repeat within a cage.
The purple line connects consecutive digits in some order.
Clarification - The shading of cells on the purple line does not affect the digits on it. The line is given only for disambiguation.
Try it on the CTC app or on f-puzzles.
Puzzle:
Solution code: Row 3 (left to right) and column 1 (top to bottom); 18 digits, no spaces.

* The CTC link is missing the Renban line but I drew it in to proceed. Very interesting ruleset. I found it quite challenging but intriguing. I hope more people try this puzzle.

Lovely puzzle, with interesting constraint... flowing logic but not always obvious :-)
