# T_235

[The work as shown](https://peteryuill.art/works/T_235). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.04.18, day 111
- **Size:** 97 × 180 cm
- **Paper:** S10, Red Star Mo She Imitation Antique Chu bark, Exhibition Edition
- **Inks:** MB4, MB5, MB6
- **Phase:** P2 The Switch

- **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
- **Form:** 2
- **Tonal depth:** 2
- **Layering:** 2
- **Composition:** 2
- **Material and surface:** 1
- **Ink cover:** 86%
- **Dark share:** 56%
- **Tonal steps:** 7

- **Flaws named by the reads:** water stain 5, other 2, mud 5, tide line 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:** 9

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_235, tone-stretched]

![T_235, classed by brightness]

86% of the sheet carries ink

TONAL STEPS

## 7 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: 0.070 (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.

### READ 1, IN ITS OWN WORDS

“A sweeping arc composition close to R2. The fluent top-left arc and top-right fan stroke are offset by a bulky, flat, discoloured central black mass. Passes are legible at the edges and fused in the centre, and the sheet is crowded.”

Form · BUILT

Top-left arc and top-right fan stroke have travel and taper; the central-bottom black mass is a bulky fill with no stroke shape, and it has a hard vertical edge.

WEAKEST Central black mass, a bulky undefined blob

STRONGEST Top-left dry-brush arc sweeping into a tapered point

Tonal depth · MODELLED

Seven tonal steps; the right-side greys and the top-right fan show banding and grain. The bottom-centre black is uniform and cloudy inside. Modulation 0.07 is moderate.

WEAKEST Bottom-centre black core, flat and dead

STRONGEST Right grey masses with stepped, grained density

Layering · LEGIBLE

Grey arcs and washes are legible under the black strokes at the right and top-left, but the central overlaps merge into dense black, so the order can't be read there.

WEAKEST Centre, where passes fuse into one dark

STRONGEST Translucent grey sweeps under black on the right

Composition · WORKING

A bowl-shaped arc gives a clear direction and the top paper is shaped, but 86% coverage and a heavy bottom-centre mass crowd the lower half.

WEAKEST Crowded heavy centre and lower band

STRONGEST Large circular sweep carrying the eye left to right

Material and surface · FLAWED

In the colour view, a brownish, cloudy tint and a hard vertical seam edge sit inside the principal central dark mass, visible at viewing distance. The splatter and drips elsewhere are controlled.

WEAKEST Brownish cloudy discolouration inside the central black

STRONGEST Dry-brush grain in the top-left arc

FLAWS

## 8 distinct places, 3 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 8 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), 8 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 31% crisp, 44% soft or bloomed, 25% broken.

RULE 1 Two tonal steps or fewer

Tonal depth held at rung 1. 7 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.

MEAN RUNG 1.80 (2.0 + 2.0 + 2.0 + 2.0 + 1.0) ÷ 5

RAW 4.60 1 + 2 × 1.80

RATING 5.0 5 + 2.086 × (4.60 − 4.60)
