Let there be chaos

Divide the grid into regions of orthogonally connected cells. Place the digits 1-9 once each in every row, column, and region.
A digit in a circle indicates exactly how many circles contain that digit. A digit in a circle also indicates how many of the up-to nine surrounding cells (including itself) are in the same region as that circle.
Digits in cells separated by a white dot are consecutive. Digits in cells separated by an X sum to ten. Not all dots and X's are necessarily given.

That took quite some doing! I'm glad that there was a somewhat simple-ish digit to fill out all 9 of early on, so I could get to coloring the regions. Wound up doing some light bifurcation to finalize the last 3 cells of r9c1's region, but I suspect I missed something or didn't recognize a pattern to avoid that.
