Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.21, day 114 - **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:** 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:** 2 - **Composition:** 3 - **Material and surface:** 2 - **Ink cover:** 72% - **Dark share:** 52% - **Tonal steps:** 5 - **Flaws named by the reads:** bloom 6, other 4 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:** 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_251] ![T_251, tone-stretched] ![T_251, classed by brightness] 72% of the sheet carries ink TONAL STEPS ## 5 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: 0.054 (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.

The bulky, largely flat black mass at the right holds back form and tone. The surface is mostly sound, with minor rim mottling.” Form · BUILT The main arc follows the brush's travel and its walls hold, with grooves tracking it. The right-hand black mass is slab-like and lobed at the top edge, not shaped by a stroke. WEAKEST Bulky, lobed dark mass at right edge STRONGEST Sweeping bowl arc with parallel groove lines Tonal depth · MODELLED Modulation 0.054. The bottom of the bowl shows streaks, grain and arcs. The left arm grades from grey to dark. The top of the right mass reads as near-uniform black. WEAKEST Upper right black mass largely flat STRONGEST Bottom band with streaks, grooves and graded greys Layering · LEGIBLE There are three passes: the pale arc, the mid-grey sweep and the black pass. They stay legible on the left and at the top. On the right the black largely covers what lies beneath. WEAKEST Dark right mass covers earlier passes STRONGEST Pale grey arc in the top centre over mid-grey left arm Composition · COMMANDING One continuous sweep carries the eye from top left down through the bowl to the right. The empty upper centre is a shaped void that works with the ink. The weight on the right presses against the edge. WEAKEST Right edge heavy and crowded by black mass STRONGEST Bowl arc framing the empty upper-centre paper Material and surface · SOUND The ink is controlled and the groove lines are crisp. There is mottled, cloudy granulation along the inner rim at the centre and some drips at the top right. All are minor, and none is a large stain. WEAKEST Cloudy, mottled fringe along the inner rim of the bowl STRONGEST Dry-brush streaks and grooves in the bottom band 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, 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 15 edge segments, 7% crisp, 67% soft or bloomed, 27% broken. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 5 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.
