Playtesting caught the gap with a sticky wand: a target visible
through the opening but one square off the corridor axis was refused.
The colinear-only model was stricter than the rulebook, whose actual
instruction is to treat the connected edges as adjacent boards with a
straight center-to-center line — and a straight line through a
one-cell opening may run diagonally, exactly as through a doorway.
hasWarpLineOfSight now abuts the far side virtually at the mouth
(rotating when the pairing turns a corner, as aisle warps do), finds
where the center-to-center line crosses the rim, requires that
crossing to fall strictly within the open mouth (corner-grazing stays
blocked — the strict reading), and checks the two legs against real
walls on each side of the seam. hasLineOfSight's core became a shared
segmentClear to serve both legs. The colinear corridor cases remain
as the special case they always were; a new test pins that off-axis
squares are visible through mouths.
