Rev 20: the junction wall rolls for its allegiance

The rulebook (Cards And Actions That Change The Map): a CREATE WALL
or DESTROY WALL alteration on a junction between sectors rolls a
50-50 when "some other moron" rotates one of them — 1-2 stays with
the standing sector, 3-4 travels with the moving one, per the book's
own low/high convention. Both rotation and relocation roll (the same
seam tears either way), demolished holes roll alongside conjured
walls, the pips land loud in the chronicle, and a traveling edge
rides anchored to its in-sector cell. Rev-gated: the roll consumes
dice that stored games never spent.
