Public verifier
This runs in your browser, not on our server. It recomputes the manifest hash, the commit hash and the entire shuffle from published values only, so nothing here takes our word for anything.

Commit-reveal shows we did not change the answer after committing. It does not show we did not go looking for a favourable seed before committing — an operator can generate many candidate seeds, see which one buries the chase in a slot nobody reaches, and publish that commit. Every check on this page would still pass.
Closing that means binding the shuffle to a public value that does not exist yet, such as a Bitcoin block hash at a stated future height, so there is nothing to grind against. We have not built that yet. Saying so seemed better than implying otherwise.
Demo data, so you can break it. Almost every certification number here is prefixed DEMO-; the few real ones are owned slabs included to test the image paths. None of it is inventory for sale.
The artifacts exactly as published.
Every published value checks out.
