Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.05.07, day 130 - **Size:** 97 × 180 cm - **Paper:** S12, Red Star Mo She Special Effect Xieyi, half-raw - **Inks:** MB6, MB7, MB8 - **Phase:** P2 The Switch - **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:** 5.3 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1.4 - **Ink cover:** 85% - **Dark share:** 42% - **Tonal steps:** 4 - **Flaws named by the reads:** water stain 8, tide line 4, other 6, bloom 1 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_293] ![T_293, tone-stretched] ![T_293, classed by brightness] 85% 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: 0.052 (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 black core is flat and its end is blunt, and pale blots and drips near the centre weaken the surface.” Form · BUILT Large spiral arc and right vertical stroke are coherent and follow brush travel; black inner arc ends in a stubby blunt block with drips at centre. WEAKEST Blunt, dripping terminus of black inner arc STRONGEST Broad outer grey arc sweeping left to top Tonal depth · MODELLED Outer arc and right stroke show bristle streaks, spotting and stepped greys; inner black arc near centre is largely uniform. Modulation 0.052 just above flat threshold. WEAKEST Dense black inner arc core reads flat STRONGEST Outer grey arc with bristle banding and grain Layering · LEGIBLE Grey outer pass, black inner pass and pale lower washes are distinguishable; overlaps legible but sequence does not build much depth beyond two or three passes. WEAKEST Pale lower-right washes faint and indistinct STRONGEST Black inner arc laid over grey outer arc Composition · WORKING Spiral drives the eye around a shaped white centre, answered by the right vertical stroke; lower right pale zone is vague and weakly held. WEAKEST Lower-right pale area loose and undefined STRONGEST Spiral sweep around shaped central white Material and surface · FLAWED Pale cloudy wash blots and tide edges sit against the grey mass end near centre-right; drips and stray spatter below black arc; milky patch lower left inside arc. WEAKEST Cloudy blots beside the black arc terminus STRONGEST Dry-brush bristle edges on right vertical stroke 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, 19 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), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 21% crisp, 58% soft or bloomed, 21% 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. 2 major flaws: applied RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.4 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.3. 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.
