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:** 7.5 - **Form:** 3 - **Tonal depth:** 2 - **Layering:** 3 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 70% - **Dark share:** 59% - **Tonal steps:** 6 - **Flaws named by the reads:** water stain 4, other 5, bloom 1, tide line 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. ## 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_372] ![T_372, tone-stretched] ![T_372, 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: 0.050 (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 short of R3 on tonal depth and composition, with a cloudy upper wash and a leftover bottom-left corner.” Form · FLUENT Fan of arc strokes follows the brush's rotation; dark central arc ends in a clean curved tip; stepped right edges are exact, outer left grey softer. WEAKEST Pale outer left sweep, edges softening into wash STRONGEST Central dark arc with crisp curved tail Tonal depth · MODELLED Dark arc shows fine concentric streaks and a pale ridge line; modulation 0.0496 only just above flat; upper grey interior cloudy rather than modelled. WEAKEST Cloudy mottled grey in upper-middle wash STRONGEST Concentric streaked banding in dark central arc Layering · ORDERED Several translucent passes fan out in visible steps on the right, dark arc laid over greys; order readable across the sheet, slightly muddled at top centre. WEAKEST Upper-middle overlaps blur into cloudy grey STRONGEST Stepped translucent fan edges on right Composition · WORKING One large fan mass sweeps diagonally with clear rotation; top-right paper with drips shaped, but bottom-left empty space is leftover and single mass lacks tension. WEAKEST Bottom-left corner paper feels leftover STRONGEST Diagonal fan sweep from upper left to lower right Material and surface · SOUND Ink controlled with dry-brush streaks in arc; upper-centre grey has cloudy mottle and faint tide edges; drips and spatter at top edge, pink tint lower right is colour. WEAKEST Cloudy mottled patches in upper grey wash STRONGEST Dry-brush streaking in dark arc 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, 11 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), 2 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 14 edge segments, 57% crisp, 21% soft or bloomed, 21% 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. 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.
