Tatlins Turm (Chaos Construction)

Tatlin's Tower
I really enjoyed this puzzle by ___ and wanted to create something similar with renbans. Have fun!
Normal Chaos Construction rules apply. Each row, column, and to-be-determined 9-cell region contains the digits 1-9 exactly once each.
Cells connected by a purple line form a renban group, i.e., they each contain a set of consecutive digits in any permutation.
A cell containing an arrow and the digit N marks one end of a straight stretch of N cells belonging to the same region (N can be any digit from 1 to 9). The next cell in that direction, if any, must be of a different region. N.B.: the cell behind the arrow, if any, may or may not belong to another region.

Solution code: Row 3, then column 6, whereby the region borders are represented by hyphens (-). Also include a hyphen between the 9-digit groups, e.g.: 12-3456-7-89-9-8-76-543-21.

Easy and sweet puzzle. A little confused about what it was doing in the 5-star category, so I took liberty to nudge it down a bit :)
Some nitpick about the rules: It mentions **THE** "next cell in that direction", which implies that there must *be* a next cell (i.e. an arrow can't see straight to the edge). To avoid this problem, I'd suggest the standard phrasing for vision counting: "...number of cells it sees in the indicated direction, including itself. region borders obstruct vision."

Thanks for solving! I feel sure that no one will doubt your solving prowess after seeing this comment. I will add an ‘if any’ at the end of the clause in lieu of the ‘vision’ formulation, though.

Hi cam, long time no see. Glad you got through it! And your rating might have tipped it over the edge to 5 stars... who knows.
Thanks also to Lavender Gooms and samuel for your comments.

I got stuck really hard on this puzzle. Felt a lot more like 5 stars than 4 to me, but the people have spoken. Great puzzle :)
