Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.06.14, day 168 - **Size:** 97 × 180 cm - **Paper:** S10, Red Star Mo She Imitation Antique Chu bark, Exhibition Edition - **Inks:** MB4, MB5, MB6 - **Phase:** P3 The Floor Rises - **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:** 7 - **Form:** 2 - **Tonal depth:** 2.4 - **Layering:** 3 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 88% - **Dark share:** 58% - **Tonal steps:** 3 - **Flaws named by the reads:** water stain 4, other 5, mud 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. ## Peter's own rating - **Rating:** 7 Peter's rating is his own eye, not the engine's, and he never gives a 10. > “There is always something that can be done better.” Peter Yuill · 2026.07.02 ## Older engine - **V10C:** 7 From an earlier engine (V10C). 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_351] ![T_351, tone-stretched] ![T_351, classed by brightness] 88% of the sheet carries ink TONAL STEPS ## 3 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: 0.066 (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 central slabs are blocky and the negative space is thin, so it falls below R3.” Form · BUILT Radial fan strokes and the right ring follow the brush's arc. The central dark slab and the lower-right wedge read as filled blocks with heavy outlines. WEAKEST Bulky central slab, blocky and stiff at its joins STRONGEST Right vortex ring arcs following brush travel Tonal depth · DEEP Modulation 0.066 and three tonal steps. Arc banding and dry-brush streaks run inside the central and left masses, with a wide range of greys between black and paper. WEAKEST Top-right black mass dense, only grainy inside STRONGEST Central slab with banded arcs and stepped greys Layering · ORDERED Many translucent arc passes overlap, and their order can be read across both vortices. Overlaps build depth. Some centre-lower overlaps are getting dense. WEAKEST Centre-bottom overlaps thickening toward murky grey STRONGEST Translucent stacked fans at left vortex Composition · WORKING Two vortex centres at left and right set up a strong horizontal pull. Ink covers 88% of the sheet, so there is little shaped empty paper and the middle is jammed with slabs. WEAKEST Crowded centre, almost no breathing paper STRONGEST Paired vortex eyes linked by radiating fans Material and surface · SOUND The ink is controlled overall. Faint cloudy patches in the upper-centre greys and small speckled spots in the lower centre are minor and away from the main dark cores. WEAKEST Cloudy milky greys in upper centre STRONGEST Dry-brush grain on the right ring FLAWS ## 4 distinct places, 0 major. Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 4 distinct places, 10 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. GEOMETRY ## Measured from the 16-bit master. The previous engine (V22) measured this sheet's master file: 2 principal ink masses traced (cyan), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 56% crisp, 25% soft or bloomed, 19% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 3 steps: not applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. none named RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 2.0 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 7.0. 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.
