Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.05.24, day 147 - **Size:** 97 × 180 cm - **Paper:** S10, Red Star Mo She Imitation Antique Chu bark, Exhibition Edition - **Inks:** MB4, MB5, MB6, MC - **Phase:** P3 The Floor Rises - **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:** 6.5 - **Form:** 2 - **Tonal depth:** 2 - **Layering:** 2.6 - **Composition:** 2.2 - **Material and surface:** 2 - **Ink cover:** 72% - **Dark share:** 58% - **Tonal steps:** 6 - **Flaws named by the reads:** water stain 4, other 4, tide line 3, ring 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. ## Peter's own rating - **Rating:** 9 Peter's rating is his own eye, not the engine's, and he never gives a 10. > “There is always something that can be done better.” Peter Yuill · 2026.07.02 ## Older engine - **V10C:** 8 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_318] ![T_318, tone-stretched] ![T_318, classed by brightness] 72% 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: 0.062 (under 0.045 reads as flat). FIVE READS ## Five reads, agreeing on 3 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 has clear translucent layering and a well-shaped white void, but the bottom-left terminal is blunt and the black mass reads flatter than R3's. Overall it is a solid, ordinary sheet.” Form · BUILT The main arc holds and follows the brush's travel to the bottom right. At the bottom left the arc ends in clumsy, slab-like wedges with awkward joins. WEAKEST Blunt stacked block terminals at bottom-left of arc STRONGEST Main black arc sweeping to bottom right Tonal depth · MODELLED The outer grey bands step and grade well. The tone-stretched view shows mottling and banding inside the dark arc, but at viewing distance its left portion reads as fairly uniform black. WEAKEST Black arc's left half reads flat in colour STRONGEST Graded translucent outer bands at upper left Layering · ORDERED Several translucent grey passes overlap in a readable order on the left and top. The red arc pass sits legibly over the grey at upper right. WEAKEST Dark arc covers underlying passes rather than reading through STRONGEST Stepped translucent bands overlapping at upper left Composition · WORKING The big arc carries the eye from bottom left over the top and down to the right, and frames a shaped white void. The bottom-left end is jammed, and the top-edge form is cramped. WEAKEST Crowded broken terminal at bottom left STRONGEST Empty circular interior framed by the arc Material and surface · SOUND The ink is controlled. Blotchy patches inside the black arc show mainly in the tone-stretched view. Faint grey marks on the left paper are small. The red drops are deliberate colour. WEAKEST Cloudy mottling inside the dark arc STRONGEST Dry-brush streaks in the outer grey bands 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, 12 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: 3 principal ink masses traced (cyan), 1 enclosed void at true size in its grid cells (amber), the main gesture from start to end (red). Of 20 edge segments, 25% crisp, 70% soft or bloomed, 5% 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 6.5. 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.
