Isofill Chaos Deconstruction: Place nine non-overlapping regions into the grid, each with nine orthogonally connected cells. Each region has a digit associated with it and every cell in that region contains that digit. All of the digits from 1 to 9 must appear in the grid. Fill every cell outside a region with the digit zero.
Zipper Lines: Digits an equal distance from the centre of a lavender line must sum to the digit in the central cell of that line (marked with a circle).
Dots: Two cells connected by a white dot contain consecutive digits. Two cells connected by a black dot contain digits where one is double the other.

Inspired combination of rulesets leading to very nice deductions. Seemed to have to test a few cases to solve the SE zipper but maybe I missed a clearer way of thinking about it. Otherwise, very smooth! Thanks!

Very fun! This was my first time solving isofill and my first time solving chaos deconstruction, but it still felt very clear how to navigate all the rules.
Zipper lines work perfectly with this combination!
