CrSb0001 has been studying the minimum number of clues to force a unique solution in Hidato for variously sized boards. They came up with a 5x5 Hidato with 5 clues but it was found that it has multiple solutions.

Goal of Hidato:

Fill in a grid with a series of consecutive numbers that connect each other horizontally, vertically, or diagonally.

I was able to find a 5x5 Hidato puzzle with just 4 clues having a unique solution. This was verified with a Picat program. Can you find one?
