Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.06.06, day 160 - **Size:** 70 × 140 cm - **Paper:** S6, Qing Yi half-raw - **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:** 6.7 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 3 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 80% - **Dark share:** 61% - **Tonal steps:** 4 - **Flaws named by the reads:** other 10, bloom 2 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_345] ![T_345, tone-stretched] ![T_345, classed by brightness] 80% 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: 0.050 (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.

It falls below R3 because the lower-left blocks are stiff and heavy and some dark interiors are flat.” Form · BUILT Arc bands follow the brush's curve with clean, held walls; the lower-left cluster of rectangular blocks is stiff and filled in, and its joins are clumsy. WEAKEST Left stacked rectangles, blunt and slab-like STRONGEST Concentric arc bands sweeping across the top right Tonal depth · MODELLED Grain and stepped greys run through the upper arcs; the dark inner right band and the lower-left darks are nearly uniform. Modulation of 0.0496 is barely above flat. WEAKEST Inner dark right arc band, near-flat interior STRONGEST Upper arcs with dry-brush grain and banding Layering · ORDERED Several translucent passes overlap in a readable order across the arch, building depth; the left blocks stack less clearly. WEAKEST Left block cluster, overlaps partly covering each other STRONGEST Overlapping translucent arc bands in the top centre Composition · WORKING The great arch carries the eye around the white central void, which has a strong shape; the lower-left mass sits heavy and somewhat apart. WEAKEST Crowded lower-left block cluster detached from the arch STRONGEST Arch framing the shaped white void at centre Material and surface · SOUND Ink is controlled, with dry-brush edges on the arcs. Small dark blots sit in the lower-left mass and minor spatter at top left; neither damages a principal area much. WEAKEST Dark pooled blots inside the lower-left mass STRONGEST Dry-brush grain at the edges of the arc bands FLAWS ## 3 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 3 distinct places, 12 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), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 63% crisp, 32% soft or bloomed, 5% 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 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 6.7. 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.
