So here's a standard Nurikabe puzzle.
I'll be using the final (solved) grid for my upcoming local puzzle competition logo as it will spell the abbreviation of the competition name. So, what does it spell?

It seems to me like the intended solution was for the magenta cells to be shaded, forming the answer KPK.
With the 10 clue moved, the solution is now unique.
