The delta — a purchase prototype
Permitted on the left, expected on the right, and the gap filling itself in between.
Nothing on this page can be bought. This is a prototype of a purchase flow, not a purchase flow. No brief reaches us, no payment link is behind anything here, and which of the five (if any) becomes the real one is not decided. specified, not built 11 Sep 2026
The work it configures is done by people, and the team specified for it has never run. Which parts of it could later be done without them is a decision nobody has taken. specified, never run 11 Sep 2026
| What it is testing | Whether the product explains itself. The middle column is the thing being sold, computed live from two lists the buyer ticks, so nobody has to be told what excess authority means. |
|---|---|
| What is wrong with it | It asks for both halves before it shows anything, and the honest answer to the right-hand column is often that nothing is written down. |
| What it produces | One JSON brief, identical across all five prototypes. The interface is the variable; the document is not. |
This prototype needs JavaScript. Everything it does happens in this browser: there is no form on this site and no page here opens a network connection, so with scripting off there is nothing to fall back to except the description of what it would do.
