Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.07.28, day 212 - **Size:** 97 × 180 cm - **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper - **Inks:** MB6, MB7, MB8, MC - **Phase:** P3 The Floor Rises - **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 - **Form:** 2 - **Tonal depth:** 1 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 86% - **Dark share:** 63% - **Tonal steps:** 4 - **Flaws named by the reads:** other 10, water stain 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 - **V10C:** 9 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_364] ![T_364, tone-stretched] ![T_364, classed by brightness] 86% 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: 0.033 (under 0.045 reads as flat). FIVE READS ## Five reads, one answer. Each quality placed on its ladder by each read, and the mean the engine keeps.

The dense, flat black wedges crowd the sheet and bury the layering. The translucent fringes and central ring carry it. Overall an ordinary sheet.” Form · BUILT Radial arc segments follow the brush's travel and hold their walls. The large black wedges at bottom left and upper right are slab-heavy and filled in. WEAKEST Bulky black wedge at bottom left STRONGEST Inner ring and cut arc around the central circle Tonal depth · THIN Dark interior modulation of 0.033 counts as flat. The big black wedges show only faint banding. Greys exist mainly at the fringes and edges of the passes. WEAKEST Flat black interior of the upper-left wedge STRONGEST Grey arc fringes on the right fan Layering · LEGIBLE Several grey passes stay legible where they step out around the wedge edges. The violet ring sits under the black. The dense black passes hide the earlier layers. WEAKEST Black wedges cover the earlier passes beneath them STRONGEST Stacked translucent grey arcs at the fan edges Composition · WORKING A clear radial structure pivots on the white central circle. With 86% ink coverage the sheet is crowded and heavy, and the empty paper is mostly leftover corners. WEAKEST Crowded lower-left quarter with little empty paper STRONGEST Radial fan around the open central circle Material and surface · SOUND The ink is controlled. The violet is deliberate. There is a small violet run at the left edge and a few specks of paper spotting at bottom right, all away from the principal masses. WEAKEST Violet drip run at the left edge STRONGEST Dry-brush edges on the ring arcs 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, 11 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: 1 principal ink mass traced (cyan), 7 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 53% crisp, 40% soft or bloomed, 7% 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. none named RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.0 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.0. 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.
