THE DIAMETER OF THE TAPERED BALL STUD WHERE IT SEATS IN THE ARM OR KNUCKLE, as a numeral with a length unit - the trade's `Cone Size`, and the first thing a fitter measures. Lemforder publishes `Cone Size: 22 mm` on the ball joint 31007 01, TRW the same on the JBJ779, Lemforder `20 mm` on the tie rod end 33927 01 and `16 mm` on the 18003 02. CARDINALITY MANY, on a published instance and not on a guess: febi's 32412 prints `Cone Size 1: 16 mm` AND `Cone Size 2: 23 mm` on ONE ARTICLE, a joint with a stud at each end of different sizes. IT IS A DIAMETER AND NOT AN ANGLE, which is stated because the engineering fact behind it is a taper: no maker read at the mint publishes a cone ANGLE, and inventing one would have been a fabrication [A8]. It is deliberately not the spine's `diameter`, which is the product's own overall size, for the reason the spine's own definition already gives about a named part's dimension. THE ATTRIBUTION GAP IS RECORDED RATHER THAN HIDDEN [A-13]: this slot is the only per-place numeral in the batch WITHOUT a place qualifier - `ring_width` carries a required `ring_position` and b155's `electrode_material` and `electrode_tip_diameter` both carry a required `electrode_side` - and it is left unqualified because the reading is unsettled. febi's two figures may be two studs on a two-ended article or the two ends of ONE taper, and the remedy differs completely between them: a place token against a small-end/large-end pair that is one fact in two numbers. Settle it off a maker's drawing, then qualify. Binding obligation. Concern measurement.
