# T_281

[The work as shown](https://peteryuill.art/works/T_281). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.05.07, day 130
- **Size:** 97 × 180 cm
- **Paper:** S12, Red Star Mo She Special Effect Xieyi, half-raw
- **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:** 6.2
- **Form:** 2.4
- **Tonal depth:** 2
- **Layering:** 3
- **Composition:** 2
- **Material and surface:** 1
- **Ink cover:** 74%
- **Dark share:** 15%
- **Tonal steps:** 4

- **Flaws named by the reads:** tide line 1, other 10, water stain 4, bloom 2

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:** 4

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_281, classed by brightness]

74% of the sheet carries ink

TONAL STEPS

## 4 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: 0.044 (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.

### READ 1, IN ITS OWN WORDS

“A fluent spiral of nested translucent arcs closing on a dry-brush black core, similar in type to R3. It is let down by a flat black interior and the hard-edged runs and drips at bottom-left.”

Form · FLUENT

All principal arcs follow the brush's circular travel; black core and grey bands are fluent. The squared terminal of the dark arc at centre is slightly blocky.

WEAKEST Squared blunt end of the black core arc

STRONGEST Dry-brush black arc sweeping round the right

Tonal depth · MODELLED

Grey bands and dry-brush right arc are modelled with streaks and grain. The black core near centre is flat inside; dark interior modulation 0.044 is below the threshold.

WEAKEST Flat dense black at the core arc's end

STRONGEST Streaked dry-brush greys in the right arc

Layering · ORDERED

Four tonal steps: pale outer arc, mid-grey arc, darker arc, black dry-brush core. The arcs overlap translucently, and their order reads clearly from the outside in.

WEAKEST Pale outermost arc barely separates from paper

STRONGEST Stepped translucent arcs nesting toward black core

Composition · WORKING

The spiral sweeps from top left down into the white void at bottom centre, so the empty paper is shaped. The bottom-left drips and pale runs are a weak, untidy corner.

WEAKEST Drip-strewn bottom-left zone

STRONGEST Spiral carrying eye into shaped white centre

Material and surface · FLAWED

The dry-brush grain is used well, but tide-edged runs and drops hang from the left grey arc in the bottom-left. They are clearly visible in the colour view. Paper creases cross the upper right.

WEAKEST Runs and drops below left grey wash

STRONGEST Dry-brush splitting in the black arc

FLAWS

## 6 distinct places, 1 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, 17 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, 19% crisp, 63% soft or bloomed, 19% broken.

RULE 1 Two tonal steps or fewer

Tonal depth held at rung 1. 4 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 6.2.

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.

MEAN RUNG 2.08 (2.4 + 2.0 + 3.0 + 2.0 + 1.0) ÷ 5

RAW 5.16 1 + 2 × 2.08

RATING 6.2 5 + 2.086 × (5.16 − 4.60)
