No deterministic function can pass both. The correct answer under the docstring rules is 3 (BBWW.. \u2192 ..WWBB \u2192 WW..BB \u2192 WWBB..), consistent with the mirror case ('WWBB','BBWW')==3 on line 14. A straightforward BFS over states (board of n+2 cells with an adjacent '..' pair; each move sends an adjacent stone pair into the empty cells, order preserved; \u2264(n+1)\u00b72^n states, runs in ~0.3s for n=14) passes 23/24 assertions + all doctests; only the erroneous line 15 fails."
