Shifter Dots

Some advice for the general approach if you want it (highlight the text to read): Coloring will likely be helpful.



Rules:
Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Shifter dots: Digts on different sides of a shifter dot must always share either parity (even/odd) OR polarity (high/low) - never neither, never both. Shifter dots can never have 5 on it.

Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are shown.

Region sum lines: Digits along region sum lines have the same sum within each box the line passes through. I.e. if a line has 1,2,3 on it in one box, and only 1 digit in another box that digit has to be 6. If the line enters a third box with 2 digits on it, those would have to be either 2,4 or 1,5, so the total is 6 in all the boxes. Digits may repeat on lines.
