Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.12, day 105 - **Size:** 97 × 180 cm - **Paper:** S12, Red Star Mo She Special Effect Xieyi, half-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:** 5.5 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1.6 - **Ink cover:** 77% - **Dark share:** 45% - **Tonal steps:** 5 - **Flaws named by the reads:** other 8, water stain 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. ## Older engine - **V7:** 8 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_208] ![T_208, tone-stretched] ![T_208, classed by brightness] 77% of the sheet carries ink TONAL STEPS ## 5 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: 0.040 (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.

The upper layering is legible, but the black is flat, the lower-left end is blunt and the arc crowds the sheet. It is ordinary overall.” Form · BUILT One great arc built from banded strokes; upper bands are fluent, but the lower-left black end is a blunt wedge and the right end loosens into dissolving grey. WEAKEST Blunt dark slab end at lower left STRONGEST Upper translucent arc bands following brush travel Tonal depth · MODELLED Five tonal steps, with stepped greys and dry-brush streaks in the upper and right arc; the left black mass reads flat (modulation 0.040). WEAKEST Flat black interior of left mass STRONGEST Stepped grey bands along upper arc Layering · LEGIBLE Three or four arc passes stay legible as stepped bands at the top; underneath, the lower passes merge into a general grey, so the order is less clear. WEAKEST Lower band where passes blur together STRONGEST Stacked translucent bands along top edge Composition · WORKING A single arc fills 77% of the sheet and gives clear movement, but the empty paper is mostly leftover margin and the lower-right end goes soft. WEAKEST Crowded lower-right, little shaped paper STRONGEST Sweeping arc carrying eye left to right Material and surface · SOUND Ink is controlled and the spatter is deliberate. Paper creases cross the central dark and a slightly cloudy grey sits in the lower band; neither is a major disruption. WEAKEST Crease lines crossing dark mass STRONGEST Dry-brush streaking in upper bands 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, 13 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: 1 principal ink mass traced (cyan), 3 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. 5 steps: not applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. 2 major flaws: applied RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.6 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.5. 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.
