Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.08, day 101 - **Size:** 97 × 180 cm - **Paper:** S11, Red Star Mo She Special Effect Xieyi, raw - **Inks:** MB1, MB2, MB3 - **Phase:** P1 Warm-up - **Shown on the site:** yes (V23 rating of 5.0 or higher) - **Early storage triage:** SA: save, archive (Peter's early system, since retired) ## Measured · V23 (v23.8) - **V23 rating:** 6 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2.2 - **Material and surface:** 2 - **Ink cover:** 70% - **Dark share:** 25% - **Tonal steps:** 3 - **Flaws named by the reads:** ring 5, other 5, dead ink 2 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. ## Older engine - **V7:** 9 From an earlier engine (V7). 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_189] ![T_189, tone-stretched] ![T_189, classed by brightness] 70% of the sheet carries ink TONAL STEPS ## 3 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: 0.041 (under 0.045 reads as flat). FIVE READS ## Five reads, agreeing on 4 of 5 qualities. Each quality placed on its ladder by each read, and the mean the engine keeps. Where reads differ, they differ by one rung; close calls resolve down.

WEAKEST Central dark hook mass, bulky and lobed at joins STRONGEST Great dry-brush arc following the brush's sweep Tonal depth · MODELLED Arc shows banding and dry-brush grain; tone-stretched view shows the central dark mass flat inside; measured dark modulation 0.041 confirms flat darks. WEAKEST Central dark hook interior uniform flat grey STRONGEST Arc's streaked grain and banded dark stripes Layering · LEGIBLE Grey arc and wedge as first pass, dark hook and strokes laid over; overlaps read clearly but only two passes, not building depth. WEAKEST Dark hook simply covers the grey arc STRONGEST Grey arc under dark hook strokes remains readable Composition · COMMANDING Large arc carries the eye from bottom left over the top into the hook and out the rightward wedge; open paper below the arc is shaped and active. WEAKEST Lower-right wedge cut off, slightly heavy STRONGEST Sweeping arc driving the eye into central hook Material and surface · SOUND Dry-brush grain controlled in arc; small pale-ringed drips bottom left and fine crease cracks through arc are minor, away from main dark mass. WEAKEST Pale-ringed drops and crease lines STRONGEST Dry-brush bristle grain across the arc 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, 12 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), 7 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 27% crisp, 53% soft or bloomed, 20% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 3 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 6.0. 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.
