Gravelight Relay Berth Shelter Service Issue

A berth shelter is a room carried in a bundle, and this one expects the room to be cold, sharp, and filthy. The build combines aramid weave, titanium hardware, fluorosilicone seals, and vacuum-rated aerogel; this gravelight version adds grit-shedding basalt cloth and blunt alloy hardware. Relay connections accept a buddy line without disconnecting the primary system. The service issue favors numbered parts and an inspection trail over polish. The folded pressure bladder anchors at six points, then inflates around a rigid throat ring that accepts a standard suit hose. Patch panels overlap the floor seams, where boots, tools, and broken deck plating usually do their worst. It is a rescue refuge, not a cabin. Carbon dioxide, icing valves, and boot damage keep counting after the walls stand up.
