This puzzle was inspired by a cosmic class masterpiece called Transmission, published about 2 years ago by Qodec.
My minimal changes to Qodec's construction have been designed to produce radical effects on the logic required to solve it, making it defintely harder, from start to end.
Rules:
- Normal sudoku rules apply.
- Parity Counters: The digit on one end of a line indicates the total number of even digits on the line. The digit on the other end indicates the total number of odd digits on the line. These totals include the digits on the endpoints.
- White Dots: Digits in cells joined by a white dot are consecutive.
Lösungscode: Row 8

Fascinating setup isn't it? Loved your take on it. Brilliant construction.
Paolo De Leva: Fascinating constraint and fascinating setup. Thanks for your original creation, and thanks for your kind feedback.
I hope someone else will use parity counter lines again in the future. Marty Sears himself seemed interested.

Great puzzle! I am not sure if I played the original, but this was a beast. Some steps were extremely hard to spot, but very rewarding when finally found. Thanks.
Paolo De Leva: Sorry, I did not mean them to be so hard. My main goal was to reveal some fairly challenging but gorgeous meta-logic that was hidden behind Qodec's break-in.
I described that meta-logic in a comment to this CtC video:

Excellent puzzle :)
Paolo De Leva: Thank you. Most of the credit goes to Qodec, but I am proud of my small contribution.
