Castle Keep

Last week I solved Forgiven by James Sinclair, a gorgeous region sum line puzzle.
This inspired me to set my own region sum line puzzle, it also gave me an idea for a neat break-in.
This puzzle is the result, hope you all like it!
Thanks to Tallcat and PotatoHead for testing and feedback.
Rules:
- Normal Sudoku rules apply.
- Digits on blue lines have the same sum in each 3x3 box that the line visits.
- The digit in the gray square is even.
- The white dot is between consecutive digits (no negative constraint).
Solution code: Row 6 (9 digits no spaces)

What a cool break-in! A little more challenging at times, especially in the middle, but I loved this puzzle regardless. Thanks zegres!

Lovely puzzle. Tempted at one point to guess a digit but resisted that descent into bifurcation! I'll echo the CtC thanks for the Ren puzzles too. Such a joy when puzzles and Ren collided for a day.

Spent way more time than I should've on boxes 7, 8 and 9, but fun nonetheless! :)
