I composed a version of this puzzle back in 2022, but Stockfish found the error: ...a1=N!!
I just revised this puzzle today and Stockfish agrees that it is flawless.
White to play, mate in 5.

P.S. I unintentionally discovered the pattern through my own mucking around, and not through the internet. Pretty cool.
