Register
A register is not a spreadsheet. It is a promise that a room can be read.
Ujinu uses the register as a plain-language ledger for objects that support ordinary routines. Each row pairs a supply with its visibility, replacement cue, and owner of the final check. The goal is not perfect accounting; it is enough shared memory that the next person can act without guessing.
