Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.09.12, day 258 - **Size:** 100 × 90 cm - **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper - **Inks:** MB6, MB7, MB8, MC - **Phase:** P4 S14 - **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:** 6.8 - **Form:** 2.2 - **Tonal depth:** 2 - **Layering:** 3 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 77% - **Dark share:** 57% - **Tonal steps:** 4 - **Flaws named by the reads:** other 8, 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. ## 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_377] ![T_377, tone-stretched] ![T_377, classed by brightness] 77% 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: 0.053 (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.

It has R3's radiating arcs and layered passes but less refinement. The lower-left block is bulky. The upper block is flat inside, the top right is crowded, and minor creases show in the darks.” Form · BUILT Arc segments mostly follow brush travel with dry-brush edges; lower-left slab reads bulky, its left end dissolving into spatter rather than a held wall. WEAKEST Lower-left block, ragged spattered left end STRONGEST Right arc band curving round the open centre Tonal depth · MODELLED Stretched view shows grain and stepped density in right arcs and lower-left block; upper-centre dark block is mostly even; modulation 0.053 is only modest. WEAKEST Upper dark block, fairly even interior STRONGEST Right arcs with graded density and dark core Layering · ORDERED Several translucent passes of arcs and blocks overlap in clear order, pale outer rings under darker bands; sequence readable across right half like R3. WEAKEST Dense overlaps at top right merge slightly STRONGEST Translucent grey arcs overlapping beneath dark bands Composition · WORKING Radiating fan gives direction and the left paper is shaped by spatter and faint rings; top right is heavy and crowded, the fan cropped awkwardly. WEAKEST Crowded dark mass at top right STRONGEST Fan of arcs radiating around right-edge centre Material and surface · SOUND Ink controlled with dry-brush edges; stretched view shows paper crease lines through the dark blocks and speckled mottling in lower-left block, minor at viewing distance. WEAKEST Crease marks across dark block interiors STRONGEST Dry-brush trailing edges on arc ends FLAWS ## 5 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 5 distinct places, 10 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), 5 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 11 edge segments, 64% crisp, 36% soft or bloomed, 0% 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 6.8. 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.
