[How the engine works](https://peteryuill.art/method). WHAT THE CODE SEES ## Three views of one sheet. Left, the photograph. Centre, the tone stretch the model is shown beside it: the darkest 45% of tones spread over the whole range, so flat black, banding and stains show. Right, every pixel as the measuring code classes it: cyan black ink, deep teal translucent grey, stone the palest ink, near black bare paper. ![T_376] ![T_376, tone-stretched] ![T_376, classed by brightness] 91% of the sheet carries ink TONAL STEPS ## 2 families of tone. Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.051 (under 0.045 reads as flat). FIVE READS ## Five reads, one answer. Each quality placed on its ladder by each read, and the mean the engine keeps.

The lower dark slab is flat and bulky, and the bands crowd the frame. It is a sound, ordinary sheet.” Form · BUILT Concentric arc bands read as coherent spiral forms with holding walls; the lower-left dark block is a heavy rectangular slab with stiff, squared top edge. WEAKEST Bulky slab-like dark block at lower left STRONGEST Upper sweeping arc band following brush travel Tonal depth · MODELLED Tone-stretched view shows grain, creasing and stepped greys in upper arcs; the lower dark sweep is heavy and close to flat; only two tonal plateaus measured. WEAKEST Lower dark mass, near-uniform dense black STRONGEST Upper right arcs showing graded translucent grey bands Layering · LEGIBLE Several arc passes overlap legibly on the right and around the inner opening; red under-layer shows top-left; the lower dark pass largely buries what lies beneath. WEAKEST Dense black lower sweep covering earlier passes STRONGEST Overlapping arc segments on right edge stay legible Composition · WORKING Spiral carries the eye clockwise around a shaped white core; but the bands crowd every edge and the left margin leftovers feel unresolved. WEAKEST Crowded edges; ink fills about 90% of sheet STRONGEST Spiral movement round the shaped pale inner opening Material and surface · SOUND Ink controlled; crumpled-paper crease texture throughout; faint mottled pale patches in the lower-left black visible mainly in tone-stretched view; small specks at right edge. WEAKEST Cloudy pale blotches inside lower-left dark mass STRONGEST Dry-brush streaked edges of arc bands at right FLAWS ## 5 distinct places, 0 major. Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 5 distinct places, 11 mentions in all across 5 reads; the number in each ninth is how many times a flaw was named there. Reads agreeing on a place strengthen the evidence for one flaw; they do not multiply it. GEOMETRY ## Measured from the 16-bit master. The previous engine (V22) measured this sheet's master file: 2 principal ink masses traced (cyan), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 65% crisp, 35% soft or bloomed, 0% broken. The rating these readings produce, the rules applied and the arithmetic, with Peter's own rating where he gave one, are in [the Archive record](https://peteryuill.art/archive/works/T_376). ## Date 2026.09.12, day 258 of the Crucible Year, one of 8 paintings from that date. 0 works were registered in the fourteen days before.
