What Deep Space Citadel unlocks

Everything in the game files that lists this technology as a prerequisite; “condition” marks objects that check for it in their conditions instead.

How to get Deep Space Citadel

Research in Stellaris is drawn: each area offers 3 cards at a time, weighted by each technology's draw weight (here 50) and its weight modifiers. Tier 3 opens after 6 tier 2 technologies of the same area. As a rare technology it is drawn less often, and some rare ones only appear after an event, a relic or a special project.
