German Sums 6 (Chaos Construction Edition)

Today we have German Sums puzzle created for Scojo's prompt, as redeemed by gdc, to create an approachable Chaos Construction puzzle :-)
My inspiration for this puzzle was Ascending From Chaos by sujoyku.
According to testers, the puzzle is somewhere between high 2* and low 3*.
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Chaos Construction: Divide the grid into seven orthogonally connected seven-cell regions, and place the digits 1-7 exactly once in each row, each column and each region.

7x7 German Sums: A clue outside the grid gives the sum of all continuously adjacent digits with a difference of at least 4 up to (and not including) the first digit with a difference of 3 or less in that row or column from the direction of the clue. A digit in the first cell is always included in the sum.

For example, if row 1 is 7435162, then the sum would be 7 from the left side and 14 (2+6+1+5) from the right side.

Region Building: For each clue, all the digits contributing to its sum must belong to the same region, and the first digit not contributing to its sum must belong to a different region.
