I gave the problem to chatGPT 5.6 Sol Pro and this was the result:
> Worked for 12m 36s
> Solved

Edit: It didn't independently solve it.
> 1. Used the public reconstruction to obtain the recovered RTL/constraint structure, including the 11×11 region map and the fact that it is a two-stars-per-row/column/region, non-touching puzzle.
> 2. Then independently wrote and ran my own exhaustive solver against that recovered constraint system.
