Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.05.14, day 137 - **Size:** 70 × 180 cm - **Paper:** S3, Tanxi Jing Pi, raw - **Inks:** MB4, MB5, MB6 - **Phase:** P2 The Switch - **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:** 5.3 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1.4 - **Ink cover:** 70% - **Dark share:** 22% - **Tonal steps:** 6 - **Flaws named by the reads:** ring 6, bloom 3, tide line 3, water stain 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:** 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 - **V7:** 7 From an earlier engine (V7). 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_302] ![T_302, tone-stretched] ![T_302, classed by brightness] 70% of the sheet carries ink TONAL STEPS ## 6 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: 0.057 (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.

Ordinary overall, close to R2.” Form · BUILT Large arc right/centre reads as one travelled stroke with dry-brush tail; top-left black mass is bulky, left vertical blocks blunt and stiff. WEAKEST Bulky slab-like dark mass at top left STRONGEST Sweeping grey arc following the brush travel Tonal depth · MODELLED Arc interior shows mottled grain, banding and graded greys; six tonal steps. Top-left black mass mostly uniform except a lighter lower lobe. WEAKEST Top-left black mass largely flat inside STRONGEST Grey arc with grain, mottling and stepped density Layering · LEGIBLE Pale wide arc, darker inner grey band and black accents read as distinct passes; at left the black simply covers earlier grey. WEAKEST Black mass covers greys beneath at left STRONGEST Translucent grey arc passes overlapping legibly Composition · WORKING Arc sweeps from dark top-left down and up to top right, shaping open upper paper; left edge clustered and crowded, lower left scattered splashes. WEAKEST Crowded left edge with blocky verticals STRONGEST Large arc carrying eye left to upper right Material and surface · FLAWED Small rings/blooms at centre-left where dark mass meets arc, visible in colour view; mottled tide edges in arc start. Dry-brush right side well handled. WEAKEST Rings and blooms beside the dark mass STRONGEST Dry-brush streaking in the right arc FLAWS ## 3 distinct places, 1 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, 14 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. A major flaw holds Material and surface at rung 1. GEOMETRY ## Measured from the 16-bit master. The previous engine (V22) measured this sheet's master file: 6 principal ink masses traced (cyan), 7 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 23 edge segments, 39% crisp, 26% soft or bloomed, 35% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 6 steps: not applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. 1 major flaw: applied RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.4 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.3. 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.
