About medium hashi

Grids grow to 10×10 and island counts reach 20. Forced bridges still handle part of the solve, but you'll hit spots where no single island is fully determined. That's where elimination comes in: if placing a bridge to one neighbor would leave another neighbor unable to reach its count, rule it out.

The connectivity requirement starts to matter here. Two separate clusters forming on opposite sides of the grid means at least one bridge must link them. Keep an eye on the overall shape.
