German Shivers

This puzzle is a gift for dumediat's birthday. He convinced me to publish it here.
I hope you'll enjoy it! Have fun!
Rules
Place the digits 1 to 9 once each into the 3x3 boxes. Digits may not repeat in the same row, column, or box of the grid.
Draw shivers in the grid such that all unshaded cells are covered and no shaded cells are covered. Shivers are non-intersecting lines of at least length 3 which only move orthogonally and turn at 90° angles on any cells other than their endpoints. Shivers act as German Whispers, so adjacent digits along shivers must differ by at least 5.
When given, a dashed circle indicates an endpoint of a shiver and the digit in the dashed circle matches the length of its shiver (length is counted in cells).
A clue in a cell indicates the length of the shiver occupying that cell. A line cannot contain more than one clue, and may contain no clues. X is an unknown digit.
German Shivers is also available online on Penpa and on CTC-App.
Please leave a comment if you enjoyed the solve!
Solution code: Row 1 (left to right) followed by Column 3 (top to bottom) (12 digits in total without spaces).

Wonderful addition to the shivers family! Quite tricky to figure out what goes in the shaded cells ;)

When solving I accidentally moved the r2c5 clue to r1c6 in my mind. I don't know how I managed to never correct myself, it was always in the correct location and I must have looked at it several times. Quite hard but absolutely fascinating experience - the puzzle still solves and has some really cool logic in there.
