Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.07.28, day 212 - **Size:** 97 × 180 cm - **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper - **Inks:** MB6, MB7, MB8 - **Phase:** P3 The Floor Rises - **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:** 6.7 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 3 - **Composition:** 2 - **Material and surface:** 2 - **Ink cover:** 80% - **Dark share:** 59% - **Tonal steps:** 3 - **Flaws named by the reads:** other 8, ring 1, water stain 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. ## 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_359] ![T_359, tone-stretched] ![T_359, classed by brightness] 80% of the sheet carries ink TONAL STEPS ## 3 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: 0.047 (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 is heavier and more crowded than R3, with blockier dark masses and flatter dark interiors. The surface is mostly clean.” Form · BUILT Radial arc bands follow brush travel with dry-brush ends; the big dark block right of centre and the tall right bar read bulky and slab-like. WEAKEST Large dark slab-like rectangle right of centre STRONGEST Curved arc bands around the left radial hub Tonal depth · MODELLED Three tonal plateaus; dark interior modulation 0.047, barely above flat. Fan greys are stepped and grained, but the main dark masses stay fairly uniform inside. WEAKEST Dark rectangle right-centre, nearly flat interior STRONGEST Stepped translucent greys in upper-right fan Layering · ORDERED Many translucent passes fan out from two hubs, each blade still readable where it overlaps; the sequence builds depth from pale outer blades to dark inner masses. WEAKEST Dense dark overlap near the left hub STRONGEST Overlapping translucent fan blades, upper right Composition · WORKING Two radial centres drive a clear left-to-right sweep. Ink covers 80% of the sheet and the right half is jammed with dark blocks, so the empty paper is mostly leftover corners. WEAKEST Crowded, heavy right half with little breathing space STRONGEST Rotating sweep from left hub toward upper right Material and surface · SOUND Ink is controlled and the dry-brush edges are clean. There is a small round spot at the right edge and faint specks on the left paper; nothing damages a principal mass. WEAKEST Small dark drop at the right edge STRONGEST Dry-brush streaked blade ends, upper left FLAWS ## 2 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 2 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 17 edge segments, 47% crisp, 41% soft or bloomed, 12% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 3 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 6.7. 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.
