Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.07.28, day 212 - **Size:** 97 × 180 cm - **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper - **Inks:** MB6, MB7, MB8, MC - **Phase:** P3 The Floor Rises - **Shown on the site:** yes (V23 rating of 5.0 or higher) - **Early storage triage:** SHP: save, has potential (Peter's early system, since retired) ## Measured · V23 (v23.8) - **V23 rating:** 6.7 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 3 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 80% - **Dark share:** 62% - **Tonal steps:** 4 - **Flaws named by the reads:** other 5, dead ink 5 The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the engine's reading, and the reference the archive is measured against. ## Peter's own rating - **Rating:** 8 Peter's rating is his own eye, not the engine's, and he never gives a 10. > “There is always something that can be done better.” Peter Yuill · 2026.07.02 ## Older engine - **V10C:** 7 From an earlier engine (V10C). Its scale differs from V23's, so it is only ever compared with other readings by the same engine. ## How the number was made Read by the Visual Analysis Engine, version 23.8, on 2026.10.06: measured by code, then read 5 times by Claude Opus 5.5 against three reference paintings (R1 to R3), each read independent of the others. [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_361] ![T_361, tone-stretched] ![T_361, classed by brightness] 80% of the sheet carries ink TONAL STEPS ## 4 families of tone. Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Life inside the black: 0.045 (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. READ 1 READ 2 READ 3 READ 4 READ 5 MEAN Form 2 BUILT 2 BUILT 2 BUILT 2 BUILT 2 BUILT 2.0 Tonal depth 2 MODELLED 2 MODELLED 2 MODELLED 2 MODELLED 2 MODELLED 2.0 Layering 3 ORDERED 3 ORDERED 3 ORDERED 3 ORDERED 3 ORDERED 3.0 Composition 2 WORKING 2 WORKING 2 WORKING 2 WORKING 2 WORKING 2.0 Material and surface 2 SOUND 2 SOUND 2 SOUND 2 SOUND 2 SOUND 2.0 ### READ 1, IN ITS OWN WORDS “A radial spiral like R3, with good translucent layering, but the dominant black slab on the right is flat, bulky and crowds the sheet, which keeps form, tone and composition at an ordinary level.” Form · BUILT The left fan of arc strokes follows the brush's travel cleanly. The large right black block is a filled slab whose stepped edges are blunt and stiff. WEAKEST Bulky black slab filling the upper right STRONGEST Concentric arc strokes around the left centre hole Tonal depth · MODELLED The left fans show stepped grey densities and brush grain. The right black mass is nearly uniform inside; the modulation of 0.045 sits at the flat threshold. WEAKEST Interior of the large right black mass STRONGEST Graded translucent greys in the left radial fan Layering · ORDERED Many translucent arc and blade passes overlap and stay readable, building depth across the spiral. On the right, the black covers the earlier layers instead of sitting over them legibly. WEAKEST The right black mass buries earlier passes STRONGEST Overlapping translucent fan blades on the upper left Composition · WORKING A clear spiral carries the eye from the hole outward, and the upper-left paper is shaped. The right half is crowded and weighed down by the solid black block. WEAKEST Heavy, crowded right half STRONGEST Spiral sweep from the left hub out to the right Material and surface · SOUND The ink is controlled, the dry-brush endings are used and the pink accents are deliberate colour. The one flaw is a few small spatter dots on the upper-left paper; the right black mass reads as surface. WEAKEST Dead, flat surface of the right black block STRONGEST Dry-brush edges on the arc strokes FLAWS ## 2 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 2 distinct places, 10 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: 1 principal ink mass traced (cyan), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 38% crisp, 56% soft or bloomed, 6% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 4 steps: not applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. none named RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 2.0 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 6.7. Engine v23.8, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on 24 randomly chosen paintings so the median sheet scores 5. The scale is relative to this archive, not to painting in general, and a difference of less than half a point between two paintings is noise.
