Digits along the green line must differ by at least 5.
Digits along a brown line must alternate between odd and even.

Cells joined by an X sum to 10. Not all Xs are given.
Cells joined by a white dot are consecutive. Cells joined by a black dot have a ratio of 2. Not all dots are given.

@GrumpyMan: I used only the parity notations and it was easy to solve once you deduced which is odd and which is even.

I thought this puzzle was going to be a light diversion, but the solve path is really fulfilling. Thank You!

I loved the puzzle, but by the end my grid was confusing and looked a mess from my combined parity and high and low notation. There must be a better form of notation than what I used.
