Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.03.27, day 89 - **Size:** 70 × 180 cm - **Paper:** S3, Tanxi Jing Pi, raw - **Inks:** MB1, MB2, MB3 - **Phase:** P1 Warm-up - **Shown on the site:** yes (V23 rating of 5.0 or higher) - **Early storage triage:** PT: probably trash (Peter's early system, since retired) ## Measured · V23 (v23.8) - **V23 rating:** 5.2 - **Form:** 2 - **Tonal depth:** 2.2 - **Layering:** 2 - **Composition:** 2 - **Material and surface:** 1 - **Ink cover:** 87% - **Dark share:** 50% - **Tonal steps:** 3 - **Flaws named by the reads:** ring 10, other 7, water stain 3 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:** 8 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_148] ![T_148, tone-stretched] ![T_148, classed by brightness] 87% 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: 0.072 (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 is bulky and crowded, and visible rings at bottom left and blots along the top weaken the surface.” Form · BUILT The main dark arc follows the brush's travel and its walls hold, but it is a bulky slab. Its squared right end is stiff, and the top blots are formless. WEAKEST Scattered blots and drips along the top edge STRONGEST Main curved sweep from left to the right end Tonal depth · MODELLED Pale striations and grain run inside the band (modulation 0.072). Three tonal steps. The densest black at the right end reads mostly as flat surface. WEAKEST Darkest right end of the band is nearly flat STRONGEST Banded mid-section of the arc with striations Layering · LEGIBLE The translucent grey fan steps sit under the dark arc and stay readable at its upper edge. In effect there are two passes, with no deeper sequence. WEAKEST Dark pass mostly covers the grey fan beneath STRONGEST Grey fan layers behind the dark arc, upper left Composition · WORKING One strong curve gives the sheet direction. The white lens of paper at upper left is shaped, but 87% ink coverage crowds the frame, and the blots along the top edge distract. WEAKEST Top-edge blots clutter the empty paper STRONGEST Sweeping arc carrying the eye left to right Material and surface · FLAWED Clear circular rings sit inside the grey-dark band at bottom left and in the pale fan, all visible in the colour view. Scattered drip blots line the top edge. WEAKEST Ring marks inside the band at bottom left STRONGEST Grainy striated interior of the dark arc FLAWS ## 6 distinct places, 2 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, 20 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: 4 principal ink masses traced (cyan), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 16% crisp, 84% soft or bloomed, 0% 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. 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 5.2. 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.
