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:** 5.2 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1.25 - **Ink cover:** 83% - **Dark share:** 26% - **Tonal steps:** 5 - **Flaws named by the reads:** water stain 3, bloom 4, tide line 1, mud 1, other 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:** 6 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 4 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_225] ![T_225, tone-stretched] ![T_225, classed by brightness] 83% 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: 0.055 (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.

It has a working arc and legible greys, but the bottom-left is cloudy and crowded, and there are wash accidents next to the principal masses.” Form · BUILT The central dark arc and the right-hand fan of dry-brush strokes are coherent and follow the brush. The bottom-left dark area is diffuse and the top-left bar is stiff. WEAKEST Diffuse grey cloud bottom-left lacks a clear wall STRONGEST Central dark arc stroke rising to the right Tonal depth · MODELLED There are five tonal steps and the dark-interior modulation is 0.055. The central arc shows grain and banding. The right dark blot and the top-left bar are fairly flat inside. WEAKEST Dark blot at right centre is flat inside STRONGEST Right fan of grey streaks with stepped density Layering · LEGIBLE Pale grey washes, mid-grey sweeps and dark strokes with spatter stay mostly legible. In the bottom-left the passes blur together into a cloudy mass. WEAKEST Bottom-left overlaps get cloudy and harder to read STRONGEST Pale grey arcs under the dark central stroke Composition · WORKING A sweep carries the eye from lower left to upper right, and the paper at the top centre is shaped. Ink covers 83% of the sheet, which is busy, and the bottom-left is crowded with spatter. WEAKEST Crowded, busy bottom-left quadrant STRONGEST Sweeping arc from lower left up to the right Material and surface · FLAWED There is a milky, cloudy wash with blotchy texture across the left-centre greys and a soft grey bloom at the bottom-left. Pale tide-edged patches sit beside the right blot. WEAKEST Cloudy grey wash patch at left centre STRONGEST Dry-brush streaks in the right fan 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, 11 mentions in all across 4 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: 3 principal ink masses traced (cyan), 8 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 20 edge segments, 60% crisp, 25% soft or bloomed, 15% 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 1.3 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 4 of 5 valid THE ARITHMETIC ## V23 rating 5.2. Engine v23.8, 4 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.
