Capital District Mall is invented. Picture a shopping centre in Washington, DC being rebuilt with money from a bank loan and from investors. The investors hold their share of the project as digital records rather than paper certificates. No such customer, property or deal exists.
The pilot worked, so the whole rebuild moves onto Euthyna for a year. Same tenant, same setup, same five recorded decisions. Nothing is set up twice.
The capacity written into their agreement reflects the rebuild. The mall counts as one project. There is an agreed number of payments across the year, an agreed amount of storage for proof, and an agreed number of years the record must be kept after the loan is paid off.
Day to day it is unremarkable, which is the point. A payment is submitted with its proof. It might be a stage payment to the builder, or a drawdown, which means money taken from the construction loan. Euthyna checks it against the rules, clears or holds it, and records the outcome with the reason. The owner, the bank and the investors all read the same record, and none of them pays anything extra to look at it.
Late in the year the project director tries to open a second project for the car park next door. Euthyna refuses, because the subscription covers one project, and tells her exactly what to request. Nothing about the mall's record is affected. What she needs to ask for is Scale.
