Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.26, day 119 - **Size:** 97 × 180 cm - **Paper:** S4, Tanxi half-raw, 6-foot - **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:** 1.2 - **Ink cover:** 73% - **Dark share:** 62% - **Tonal steps:** 4 - **Flaws named by the reads:** water stain 8, ring 1, bloom 3, other 3, tide line 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:** 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_262] ![T_262, tone-stretched] ![T_262, classed by brightness] 73% 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: 0.059 (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.

An ordinary sheet, close to R2.” Form · BUILT Left arc curves fluently into a dark base; the right vertical block is a stiff rectangle; the centre-right wedge is coherent but bulky. WEAKEST Right vertical block, slab-like rectangle STRONGEST Left sweeping arc following brush travel Tonal depth · MODELLED Left arc shows graded bands inside; the right block has streaks and grain, but its dark core is flatter. Four tonal steps, modulation 0.059. WEAKEST Right block's lower dark interior fairly flat STRONGEST Left arc graded from grey rim to black Layering · LEGIBLE Translucent grey passes under and over the dark masses stay readable, especially at the top right block. The spatter at lower right confuses the order. WEAKEST Splattered lower right where the passes blur together STRONGEST Grey veils over the dark right block Composition · WORKING The U-shaped arc carries the eye from left to right and shapes the empty paper at top left; the lower right is crowded with spatter and wedges. WEAKEST Crowded, busy lower-right quadrant STRONGEST Large arc framing the open top-left paper Material and surface · FLAWED Milky, cloudy splashes and blotchy pale wash around the centre-right dark wedge, and a small ring-like blot at top left, are visible in the colour view. WEAKEST Cloudy pale patches beside the centre-right wedge STRONGEST Dry-brush streaks in the right block FLAWS ## 6 distinct places, 3 major. Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 6 distinct places, 16 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), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 50% crisp, 25% soft or bloomed, 25% 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. 4 major flaws: applied RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.2 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.2. 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.
