Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.04.26, day 119 - **Size:** 97 × 180 cm - **Paper:** S4, Tanxi half-raw, 6-foot - **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:** 81% - **Dark share:** 65% - **Tonal steps:** 3 - **Flaws named by the reads:** ring 5, water stain 7, other 3, tide line 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 - **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_267] ![T_267, tone-stretched] ![T_267, classed by brightness] 81% 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: 0.050 (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 darks show some modelling, but a ring stain in the central slab is a clear accident.” Form · BUILT The left fan and the right curved sweep hold their walls and follow the arc. The central rectangle and the grey slab beside it are blocky and stiff. WEAKEST Blunt rectangular dark block in left-centre STRONGEST Right-hand curved sweep of layered strokes Tonal depth · MODELLED Modulation 0.050 is just above flat. The tone-stretched view shows faint grain and fold lines in the left fan. The right sweep is banded, and the central block is mostly uniform. WEAKEST Central dark rectangle interior largely flat STRONGEST Right sweep with banded grey-to-black stroke density Layering · LEGIBLE There are three tonal steps. Grey arcs and pale washes sit under the darker passes and stay readable at the edges. The darks mostly cover rather than build through translucency. WEAKEST Dark central block covers earlier grey passes STRONGEST Translucent grey arcs under the left fan Composition · WORKING Two masses curve into a bowl around the open white top, which gives direction. The white crack in the centre and the dense, heavy lower half crowd the arrangement. WEAKEST Crowded heavy lower band, central gap awkward STRONGEST Bowl-shaped arc framing open top paper Material and surface · FLAWED There is a clear ring-shaped blot in the grey slab at centre, visible in the colour view. Small tide spots sit in the top paper, and crease lines show in the left fan. WEAKEST Ring stain inside central grey slab STRONGEST Dry-brush feathered edges on right sweep FLAWS ## 5 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 5 distinct places, 16 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), 2 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 31% crisp, 50% soft or bloomed, 19% 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 5.0. 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.
