Play in Sudokupad

Thank you all for solving the puzzles in this series. Based on your comments, it seems like the puzzles start on the easy side, with the dual rules placing a few digits immediately, then there is a tricky part to navigate. This puzzle is no exception to the trend. It starts with a few discoveries, then grinds to a halt. I hope you can see the multi-step logical path, or perhaps find a solution I could not to solve this parity puzzle.

Normal sudoku rules apply.

Clues outside the grid are the sum of the cells on the indicated diagonal. All digits on the indicated diagonal must also form valid parity lines. (Adjacent digits on the same diagonal must alternate parity add/even.)
