Row 57's pocket had a way out: the road east, three tiles from the fly
and resting in the blocked window. The last resort ignores that window
but narrows to the ways toward the objective, and the only one was the
gym's door beyond the fence, so the route search refused and the road
was never tried. With the refusal withheld the pad went empty and the
fly waited out the road's window, ten brain minutes.
The narrowing is a preference and the dealer cannot search. When start's
route search cannot reach the preferred ways, it tries the rest of the
last resort, nearest reachable first, exactly as every walk chooses. The
pad is unchanged; only where the pressed macro walks.
The ROM proof now asserts the fly leaves the pocket inside a brain
minute: frame 517 (0.14 minutes), against 36,325 (10.1) on the base.
