Single jail cell: three adobe walls and a slab roof under a timber cap, an iron barred front with a hinged barred door on its own node, a plank bunk on two piers and an iron pail on the floor. Dimensions 3.56 by 2.94 by 2.76 m (X by Y by Z). Metre units, +Y up, +Z front; the origin sits on the ground at the footprint centre unless stated otherwise. Sun-bleached pine, oxblood shop paint, adobe, black smith iron, brass, glass, canvas, leather, hemp rope, street dust, red sandstone and a gilt sign panel. Rigid node-transform clips open, close drive the named parts on their own pivots. There is no skinning and no skeleton; every other surface is static. The cell opens to +X. The lock and the brass plate are static; only the barred door swings.
