Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.12, day 105 - **Size:** 97 × 180 cm - **Paper:** S12, Red Star Mo She Special Effect Xieyi, half-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 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1 - **Ink cover:** 78% - **Dark share:** 37% - **Tonal steps:** 6 - **Flaws named by the reads:** bloom 3, ring 4, water stain 6, tide line 4, other 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. ## Older engine - **V7:** 4 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_210] ![T_210, tone-stretched] ![T_210, classed by brightness] 78% 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: 0.053 (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.

The dark masses on both sides are joined by a dry-brush arc. The centre is cloudy and crowded, and drips and a ring-like arc mar the surface. Most ladders sit at the ordinary rung.” Form · BUILT The left black mass and the right fan stroke are nameable shapes with clear brush travel. The centre dark mass is ragged and partly dissolved, and the top-right grey slab is stiff. WEAKEST centre dark mass, blotchy with a dissolved left edge STRONGEST sweeping dry-brush arc linking left mass to right Tonal depth · MODELLED The left mass shows dry-brush streaks and creases in the stretched view. The right fan has stepped greys. The centre black is mostly flat. Modulation is 0.053, barely above the flat line. WEAKEST centre dark mass, flatter inside STRONGEST left black mass, with grain and streaks inside Layering · LEGIBLE The grey slabs at top right and top centre sit under the dark strokes and stay readable. Near the centre the overlaps go cloudy and the order of passes is harder to read. WEAKEST centre, where grey wash and black merge cloudily STRONGEST top-right translucent slabs under the dark fan Composition · WORKING The masses at left and right are joined by a sweeping arc, and the pale top-centre paper is shaped. With 78% coverage the sheet feels crowded, and the centre is muddled. WEAKEST centre area, crowded and cloudy STRONGEST sweeping arc carrying the eye left to right Material and surface · FLAWED Scattered round drips and blots at top centre, a ring-like grey arc at bottom right, and a cloudy wash beside the centre dark are all visible in the colour view. WEAKEST drips and rings on the pale paper STRONGEST dry-brush grain in the left mass FLAWS ## 6 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 6 distinct places, 19 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: 1 principal ink mass traced (cyan), 9 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 41% crisp, 24% 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. 5 major flaws: applied RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.0 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 5.0. 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.
