Seal an AI-assisted piece of content into a permanent, checksummed receipt: the content, the prompt that produced it, what grounded it, what was invented, and the caveats. Anyone with the receipt's link can pull it up and watch the checksum verify live.
Newest sealed receipts, public by design. Each card re-verifies its own checksum every time it renders.

No fibs — what a receipt proves and what it doesn't
A verified checksum proves the sealed content has not been edited since sealing. It does not prove the content is true, complete, or good. Receipts only exist for content voluntarily sealed here — there is no way to detect AI content that never got one. The hashes live in this app's database, so "tamper-evident" means tamper-evident against this app's own records, not cryptographically unstoppable.
