The £5 sale is a download: the zip, its hash, and a check in the browser; the other three levels are a follow-up within 24 hours

The £5 page is the download. v1.19.1 said the pack would come by email and left the file to the store. The lead's answer the same day was simpler: the £5 sale lands on a page where the zip of the vault is downloaded. So the level-1 page↗ now is that page. It reads the shape from the payment link, offers the zip of that template vault, every file in it, and prints the size and the content hash beside the link; check the hash here fetches the file and hashes it in the browser, and says whether it matches what is published. With no shape on the link, or one this site does not know, the page lists all fifteen templates and the buyer picks the one on the receipt. Where a PDF edition of the vault exists, that is offered too, and every download sits beside see it live, in the vault.

The hash cannot drift. The manifest the page carries, one line per template with the zip's path, size and sha256, is stamped by build-abp-pages.mjs from the bytes under site/vaults/<slug>/dist/, the same zips the vault build writes, and the CI check that already fails on a stale library page now fails on a stale manifest. Nothing on the page is typed in by hand.

Levels 2, 3 and 4 are a follow-up within 24 hours. The working days v1.19.1 assumed are gone; each of those pages, and the after-you-pay section on Pricing↗, now says that a person follows up within 24 hours of the payment landing, and what that follow-up carries: the key at level 2, the prompt step at level 3, the first session booked at level 4. The pack, by email reads the pack, downloaded everywhere it appeared. D9 in the register↗ is updated: the zip is no longer owed, and the delivery-time assumption is no longer one.

Not done. The store's payment links still have to send the buyer here, and the level-1 link has to carry the shape (paid-t1.html?shape=<slug>&order=<ref>); until they do, nobody lands on these pages. The store's own product-page text and the opinion add-on page are the store's. The 24 hours is a commitment, not a record yet: the first order will make it one.
