The table

{{offer-table}}

The same six, by who each one was built for

This page is the price ladder. The other way in↗ is by who is climbing it — which is the question somebody actually arrives with, and the reason the home page asks it first.

The six, in full

Why each number is that number

No price on this site is positioning, and none of them is the builder's. The four were set by the project lead on 15 September 2026, replacing the four tiers of the 10 September pack, and the frozen table in the build gate was re-pointed at them in the commit that says so. The check did not loosen; it was aimed somewhere else.

{{prices-why}}

The floor moved, and the arithmetic that argued against it is still here. At £5 the fixed card fee alone is about four per cent of the transaction, which on 10 September was the reason the floor was £10 rather than £5. On 15 September the floor was set at £5 anyway, and on 16 September it went back to £10 — this time because of what the level carries rather than what it costs to take the money. Every step stays on the page, because a store that deletes the argument it lost is a store you cannot check. {{claim:card-fee-floor}}

The cheapest level is a licence, not a download. The files it sends are published free under CC BY, and anybody using them that way has to attribute them. What £10 buys is a commercial licence to you over the same material — so it can go into client work, into a product, or into a document that goes to a regulator, without carrying our name into it. That is grantable because the copyright in the pack is ours: everything in it was written here. The wording is not drafted yet, and the ledger says so rather than the page implying otherwise. {{claim:entry-level-dual-licence}}

Prices are in pounds. Pricing in euros while settling in pounds adds about two per cent, and that two per cent buys nothing. {{claim:pricing-in-pounds}}

How each one is paid for

Every level is a single price, so every level can hold a standing payment link. There is no band to fix and nothing to take a deposit against: that shape belonged to the offer line replaced on 15 September, and the ledger keeps it↗ rather than pretending it was never there. {{claim:checkout-bands-have-no-standing-link}}

No link has been created on either rail. Every card shows its code and its delivery page instead of a live button, and your order↗ names which rail is missing. {{claim:checkout-links-not-issued}} How buying works↗.

The offer identifier is the stable part

A printed code redirects to /d/<id>/ and nothing else about it is load-bearing. Not the host, not the path above it, not a word of the copy.

That is deliberate, and it is the one piece of engineering this site does purely because of a disagreement. A ruling of 10 September placed a storefront under the risk product rather than on the platform domain. The instruction in hand overrode it and named this host. The ruling stands on the record, unedited, and the build treats the host as moveable: every internal link here is relative, the host appears in no sentence of copy, and the identifiers above do not change. If the site moves, it costs a DNS record and no reprinting. {{claim:domain-ruling-overruled}}

What is not on this page

Eight further offers are specified and none of them is for this week. The amendment subscription, the divergence report, the rendering diff as a verification service, crosswalk resolution, the write-only vault link, the vault as a data room, the threat-model estate, and the infographic generator with a purchase page. They are listed here↗ so that nobody proposes them as new.
