Sealed Seed Vault (World-Sorted)

This world-sorted vault holds food, fiber, and medicinal seed grouped by gravity, day length, water chemistry, and compatible substrate. Numbered paper-foil sleeves surround a mineral desiccant core. A sound case smells of cold metal and dry grain; cellar sweetness means moisture breached a lot. Open it under dry filtered air, remove only the planting ledger's choice, and quarantine every germination tray. Colony planners and survey crews get practical cultivars. Wealthy collectors buy rare worlds and may never plant them. The sorting saves years after fire or blight, provided nobody treats categories as guarantees. Warm the case repeatedly, confuse two planetary labels, or let one moldy sleeve breathe across the rack and the first recovery crop may fail—or produce medicinal roots with the wrong chemistry and poison the people depending on them.
