[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_388] ![T_388, tone-stretched] ![T_388, classed by brightness] 84% of the sheet carries ink TONAL STEPS ## 1 family 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: 0.040 (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 arc edges and the spiral eye work; the overall sheet is ordinary to below average.” Form · BUILT Stepped arcs at the upper rim and left edge follow the brush's travel. The large central-right black mass is filled in and has lost its stroke shape. WEAKEST Central dark mass reads as a bulky filled slab STRONGEST Stepped arc strokes around the spiral's left rim Tonal depth · THIN Interior modulation is 0.040, which counts as flat, and there is one tonal step. Greys appear only at the outer edges of the arcs. The core mass is a uniform black. WEAKEST Huge central-right black mass, flat inside STRONGEST Translucent grey steps along the top-right rim Layering · LEGIBLE Several passes overlap legibly in the stepped rim at the top right and in the lower-left arcs. In the centre, the later black covers the earlier passes. WEAKEST Central mass buries the earlier passes STRONGEST Overlapping translucent bands at the top-right rim Composition · WORKING The spiral gives a clear rotational movement and the white lower left is shaped. At 84% ink coverage, the right half is jammed with dead black. WEAKEST Dark mass crowds the right and bottom STRONGEST Spiral eye leading into the white lower-left void Material and surface · SOUND There are small drips and spatters at the upper and lower left, away from the masses. Paper creasing shows in the tone-stretched view. No tide lines or rings inside the dark. WEAKEST Dead, uniform black in the centre STRONGEST Dry-brush edges on the stepped arcs FLAWS ## 4 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 4 distinct places, 15 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. 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_388). ## Date 2026.10.16, day 292 of the Crucible Year, one of 12 paintings from that date (9 shown). 0 works were registered in the fourteen days before.
