Verify a certificate
Look up a certificate by the delivery id printed on every export, and check that the set you were given is exactly the set that was certified. Nothing you paste here is sent anywhere.
1. Look up by delivery id
The UUID after "delivery" in the header of an export. Example: 281c7a20-22cb-4f96-bea4-1eb3a4c8737d
2. Check a set you were given (optional)
Paste the whole content of a text export from the app (items-….txt), or a JSON export. This page computes the set's hash and compares it with the certificate's artifact hash. Nothing you paste is sent anywhere.
What this page proves
A certificate states that a specific set (by hash) was regenerated on the server from a specific model version (by fingerprint), and that every item was checked for leftover placeholders, duplicates and answer position. It does not verify domain accuracy, curriculum fit or difficulty — see the Disclaimer.
