Outside clues are X-sums clues, which indicate the sum of the first X cells in the direction of the clue, where X is the digit closest to the clue. The first X digits are in the same region, and the X+1th digit is in a different region.
For each line, digits on the line have an equal sum N within each region it passes through. If a line passes through the same region more than once, each individual segment of such a line within that box sums to N separately.

Very nice Chaos Construction. Not hard, but lots of opportunities to make mistakes. Some of the final region shapes at the end surprised me quite a bit
