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:** S7, Qing Yi cooked - **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:** 7.5 - **Form:** 2.2 - **Tonal depth:** 2 - **Layering:** 3 - **Composition:** 2.8 - **Material and surface:** 2 - **Ink cover:** 84% - **Dark share:** 48% - **Tonal steps:** 4 - **Flaws named by the reads:** other 12 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:** 8 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_350] ![T_350, tone-stretched] ![T_350, classed by brightness] 84% 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: 0.028 (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.

It falls short of R3 because the right black mass is flat and slab-like and the weight sits unevenly. Surface flaws are minor.” Form · BUILT Rectangular wide-brush blocks step around a ring with holding walls; right-centre black merges into a heavy slab, losing individual stroke shape. WEAKEST Right black mass fuses into one bulky slab STRONGEST Stepped arc blocks at left following brush travel Tonal depth · MODELLED Outer grey bands show stepped density and brush grain; the large right black mass is flat inside (modulation 0.028). WEAKEST Interior of big right black mass STRONGEST Graded translucent grey blocks around the outer ring Layering · ORDERED Several translucent passes, pale outer to black inner, overlap legibly in stepped order across both arcs; four tonal steps. WEAKEST Black passes on right cover earlier greys STRONGEST Overlapping translucent grey blocks, left arc Composition · COMMANDING Concentric arc sweeps across the frame; vertical paper channel and lower void shape the space; right half heavier than left. WEAKEST Right side weighted heavily by black mass STRONGEST Pale vertical gap and open circle at bottom centre Material and surface · SOUND Ink controlled with dry-brush edges; small white specks in right black, faint crease lines top left, drips in central strip are minor. WEAKEST White scratch specks inside right black mass STRONGEST Dry-brush grain at block edges 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, 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), 5 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 77% crisp, 18% soft or bloomed, 6% 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 7.5. 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.
