LogicMath::sqrt is a 256-entry table of floor(16*sqrt(i)) with a seed picked by magnitude and one or two newton steps on top, and it is not exact: above 2147441940 the seed overshoots and the single correction cannot pull it back, so it answers 46341 where the true root is 46340, and 65535 for INT_MAX. that matters because the checksum is computed over whatever it returns. an honest square root would be a permanent, invisible disagreement, so this one is transcribed branch for branch - including the early -1 for negatives and the INT_MAX special case - and our own converging root is gone. checked against the exact root across the low range and the boundaries, where the two agree, and at the top, where they must not. distances now go through the saturating helper before the root, the way the client does it, rather than being squared in i64 on the way in.
