# T_339

[The work as shown](https://peteryuill.art/works/T_339). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.06.03, day 157
- **Size:** 97 × 180 cm
- **Paper:** S12, Red Star Mo She Special Effect Xieyi, half-raw
- **Inks:** MB4, MB5, MB6
- **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:** 8.2
- **Form:** 2.4
- **Tonal depth:** 2.6
- **Layering:** 3
- **Composition:** 2.8
- **Material and surface:** 2
- **Ink cover:** 78%
- **Dark share:** 52%
- **Tonal steps:** 4

- **Flaws named by the reads:** ring 1, other 5, water stain 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.

## Peter's own rating

- **Rating:** 7

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.”

## 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_339, tone-stretched]

![T_339, classed by brightness]

78% 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: 0.056 (under 0.045 reads as flat).

FIVE READS

## Five reads, agreeing on 2 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

“Fan of layered arc segments close to R3's idiom: ordered translucent passes, graded greys, shaped void. Lowest black arc somewhat bulky, right side crowded, minor blots at left keep material at sound.”

Form · FLUENT

Arc segments follow brush travel around a common centre; walls hold with dry-brush ends. Lowest black arc is bulky but still curved and made.

WEAKEST heavy lowest black arc, slightly slab-like at left end

STRONGEST upper black trapezoid segment with clean dragged walls

Tonal depth · DEEP

Modulation 0.056, four tonal steps; tone-stretched view shows arcs, grain and crackle inside black masses, and a stepped range of greys outward to paper.

WEAKEST darkest lower arc near-uniform at left end

STRONGEST right-side grey segments graded with brush banding

Layering · ORDERED

Pale grey fan segments laid first, mid greys then black over them; overlaps read clearly across top and right, building depth in sequence.

WEAKEST black arcs partly cover earlier grey passes

STRONGEST translucent pale segments overlapping at upper left

Composition · COMMANDING

One sweeping arc carries eye from left to bottom right; the inner white void and upper-left paper are shaped. Weight crowds right edge somewhat.

WEAKEST bottom-right crop feels heavy and cut

STRONGEST sweeping fan arc around the open lower-centre void

Material and surface · SOUND

Ink controlled with dry-brush edges; small blot/ring marks in pale grey at left edge; crinkle network across darks reads as paper texture, not major.

WEAKEST small pale blots in left grey wash

STRONGEST dry-brush grain at segment ends, upper centre

FLAWS

## 3 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 3 distinct places, 10 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: 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, 38% crisp, 31% soft or bloomed, 31% 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. 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 8.2.

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 2.56 (2.4 + 2.6 + 3.0 + 2.8 + 2.0) ÷ 5

RAW 6.12 1 + 2 × 2.56
