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:** SHP: save, has potential (Peter's early system, since retired) ## Measured · V23 (v23.8) - **V23 rating:** 6.2 - **Form:** 2 - **Tonal depth:** 1.6 - **Layering:** 2.8 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 90% - **Dark share:** 57% - **Tonal steps:** 3 - **Flaws named by the reads:** other 12, 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. ## Peter's own rating - **Rating:** 7.5 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:** 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_358] ![T_358, tone-stretched] ![T_358, classed by brightness] 90% 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: 0.044 (under 0.045 reads as flat). FIVE READS ## Five reads, agreeing on 3 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 layering is legible; the dark interiors measure flat.” Form · BUILT The radial wedges and arc sweeps are coherent and follow the brush. The square patches at left and the stacked bottom-right bars are slab-like and stiff. WEAKEST Blunt rectangular blocks at left edge and bottom right STRONGEST Long radial wedge down the centre, tapering cleanly Tonal depth · THIN Dark interior modulation is 0.044, under the flat threshold. The big upper-left dark mass reads as one dense tone in colour. Banding shows mainly at its edges and its lower rim. WEAKEST Large dark arc mass, upper left to centre STRONGEST Dry-brush arc banding at lower left of dark mass Layering · ORDERED Several translucent passes of arcs and radial bars. Their overlaps stay readable, especially on the right and lower edges, so the build-up of the form can be followed. WEAKEST Dense dark core where passes fuse together STRONGEST Translucent radial bars overlapping arcs on right Composition · WORKING Strong radial movement pulls the eye toward the top-centre opening. Ink covers 90% of the sheet, so the empty paper is mostly slivers and the upper left feels heavy. WEAKEST Crowded upper-left dark mass with little empty paper STRONGEST Radial convergence on the pale hole at top centre Material and surface · SOUND Ink handling is controlled overall. Two small dark blots sit in the top-centre opening and a few spatter dots at lower left. No tide lines inside the dark masses. WEAKEST Ink blots inside the pale focal opening STRONGEST Dry-brush grain at the lower rim of the 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, 13 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), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 12 edge segments, 58% crisp, 42% soft or bloomed, 0% 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 1.6 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 6.2. 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.
