Breeze and Pearl draw a few strokes a couple of centimetres apart, and the
nudge out of wall ink could leave an agent in that slit, where its cone is
a hairline running down it. Within 5 cm of blocking ink now counts as ink,
and a nudged agent stands 6 cm clear, so a slit narrower than 10 cm has no
standing point: the three reported spots step out onto open floor.
