Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.15, day 108 - **Size:** 97 × 180 cm - **Paper:** S11, Red Star Mo She Special Effect Xieyi, raw - **Inks:** MB4, MB5, MB6 - **Phase:** P2 The Switch - **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:** 5 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1 - **Ink cover:** 64% - **Dark share:** 19% - **Tonal steps:** 6 - **Flaws named by the reads:** water stain 7, bloom 3, other 8 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:** 7 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_222] ![T_222, tone-stretched] ![T_222, classed by brightness] 64% of the sheet carries ink TONAL STEPS ## 6 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: 0.067 (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 upper-left wash is cloudy and blotched, the lower centre is empty, and stray drips land on it. An ordinary sheet, close to R2.” Form · BUILT Right dark mass has strong tapering shards following the stroke; left cluster's grey washes and the small dark blob at left are lumpy, so some bulk remains. WEAKEST Upper-left grey wash: diffuse, cloudy lobe edges STRONGEST Right-edge dark fan of tapering shards Tonal depth · MODELLED Six tonal steps; dark modulation 0.067. Right mass has streaks and graded greys; upper-left grey wash reads cloudy and uniform. WEAKEST Pale grey left wash flat and cloudy inside STRONGEST Right dark mass with streaked, graded interior Layering · LEGIBLE Pale arc wash, mid-grey shards and black strokes read as separate passes on the right; on the left the overlaps soften toward haze. WEAKEST Left cluster overlaps blur into grey haze STRONGEST Right mass: dark strokes over legible grey shards Composition · WORKING Two masses at the edges bracket a curving empty centre with circular dry-brush arc at top; lower-middle is dead paper with scattered drops. WEAKEST Lower centre empty except scattered drips STRONGEST Arc sweeping from left down to right mass Material and surface · FLAWED Upper-left grey wash is cloudy with mottled blotches and crease lines; speckled bloom spots in grey arc upper right; random drips across centre. WEAKEST Cloudy blotched grey wash in upper left STRONGEST Dry-brush arc texture at top centre FLAWS ## 5 distinct places, 1 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, 18 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. A major flaw holds Material and surface at rung 1. GEOMETRY ## Measured from the 16-bit master. The previous engine (V22) measured this sheet's master file: 2 principal ink masses traced (cyan), 7 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 14 edge segments, 14% crisp, 71% soft or bloomed, 14% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 6 steps: not applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. 3 major flaws: applied RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.0 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.0. 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.
