Paste a receipt. No account. No login. You do not have to trust us — the signature checks out on its own.
Drop the file. If its hash matches the sealed hash, it is the same file, byte for byte.
Verification proves the receipt has not been altered since it was signed. It does not endorse, confirm or vouch for whatever the sealed content says. A notary works the same way — and any platform that blurs that line is worthless.
