Sazanami children are registered in a ceremony at birth. The Storehouse treats them as known objects. Sorcerers can detect the registration. Auction goods are encased; clan members are not, because the building already has their names. Weapons can be summoned. People can be stored. The first head built a subspace that is also a census.
Hakuri’s version
Hakuri can register individuals and their spiritually charged possessions in his own Storehouse. That is why a walking Kura can un-arm and re-arm bearers. The clan used registration as ownership. He uses it as logistics. See Storehouse, Naginojoen, Hakuri.
