| open aperture | terminals point outward, leaving the counter reaching the air | |
| closed aperture | terminals curl toward each other, closing the counter in | |
| AND THIS SHELF CANNOT VARY IT, which is why this entry has no page of its own | the word "aperture" appears ZERO times anywhere in the build engine's own source. The family engine's entire vocabulary is width, contrast, terminal, outline, xheight, trap, sag and legible: 33 uses of width, 20 of contrast, 16 of terminal, and not one thing that opens or closes an arc | read out of the foundry's own generator on 2026-09-11. So a graded spread of apertures across 23 families would have to be an ACCIDENT of the other transforms rather than a property anybody set. VALE found this; it is checked here against the files before the record repeats it |
| the one real difference, and it is binary rather than graded | SEVEN of the 23 families carry terminal='butt' — Extrude, Grotesk, Pixel, Poster, Press, Square and Terrace — and the other sixteen take the round default, which moves where a c's stroke stops by about half a stroke | read out of the foundry's own generator on 2026-09-11. A two-state difference is the shape that produces small ratios, and it is nothing like the 1.77 to 1 this entry's page asserted |
| WHAT THE PAGE USED TO CLAIM, and why it is going neutral | it set itself in Drew Monoline against Drew Display as an open pole and a closed one, at a spread of 1.77 to 1. Three independent measurements on 2026-09-11 put that pair at 1.20, 1.07 and 1.16 to 1 | and none of the three should be trusted either: each is absurd at its edges, one of them calling Drew Gazette the most closed face on the shelf when the render shows an ordinary open c with a slab terminal. THE GENERATOR SETTLED IT WHERE THE INSTRUMENTS COULD NOT. Three untrustworthy methods agreeing is weak evidence, not strong, because they share a premise. A term this house cannot demonstrate gets the neutral page, which is the brief's own rule and not a shortfall |
