Slaved bulkhead that seals (and crushes) a room on a coded trigger.
Corp SOPs favorite when the threat is inside, not outside. A blow-out panel triggers a
cascade: every blast door in the wing closes at once, atmosphere vents, and the pressure
differential packs an extra few tonnes per square meter against anyone still caught between
the seals. The override key is physically keyed AND digitally signed -- anyone who lost
the master token is in for a rough minute against the rams, and rough is the polite word
for what the seal does to a torso at full atmospheric differential.
