Paper is not cash at the register.
EZego
A household, a firm, and a treasury may all write named credit on the same rail. That paper is a promise. At the register it is not cash.
A bank deposit and a household invoice follow the same rule. Neither spends as if it were already money.
All eight stepsShort-term cost stability is a window lock: this write's ratio and charge stay put until the due date. That is the minimum change. The rest of the protocol stays as titled.
Live discount still moves at checkout. The book, not the mint, pays up to the locked ratio.
01
Write the receivable
Face is paper. Due date on the tape.
02
Read live discount
Conversion = face × (1 − d). No par club.
03
Lock this window
Ratio and charge for the current settlement window are listed at write. Next window may requote.
04
Desert stays residual
Desert is not used for ordinary weeks. Empty sliver is issuer loss. The floor is never the backstop.
Across the layers
01
No second sovereign
No frozen discount. No compulsory Desert tithe. Window lock is the only whole-protocol employ.
