Not a single stepper but not a BBDBer either.

Quote:
(4=8)r8c2 - (8=4)r1c2 - r1c46 = r2c4 - r89c4 = r9c5; r8c4|r9c3<>4,
x-wing 8 r18c29,
xy-wing 47-8 with vertex in r8c1
flightless xy-wing 2-47 with vertex in r8c4 plus transport of both pincers.

My solver used five steps. Since players sometimes post more steps than my solver, I thought this might qualify as a BBDB puzzle.
