# T_312

[The work as shown](https://peteryuill.art/works/T_312). 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
- **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:** 5.8
- **Form:** 2
- **Tonal depth:** 2
- **Layering:** 2
- **Composition:** 2
- **Material and surface:** 2
- **Ink cover:** 49%
- **Dark share:** 53%
- **Tonal steps:** 5

- **Flaws named by the reads:** water stain 6, other 6

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:** 8

Peter's rating is his own eye, not the engine's, and he never gives a 10.

## Older engine

- **V10C:** 9

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 4 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_312, classed by brightness]

49% of the sheet carries ink

TONAL STEPS

## 5 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: 0.046 (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

“This is an ordinary sheet. A strong dry-brush arc meets a heavy black arc that is mostly flat inside and has a stiff, blocky left end. The layering is legible but simple, and the empty left side is weak and lightly stained.”

Form · BUILT

Dry-brush arc follows the brush's travel well; the black arc holds, but its squared left end and stacked grey slab read stiff and slab-like.

WEAKEST Blocky grey slab joining black arc's left end

STRONGEST Dry-brush grey arc sweeping left from centre

Tonal depth · MODELLED

Dry-brush arc has bristle streaks and stepped greys; black arc only faintly mottled (modulation 0.046, just above flat), with banding only at its lower edge.

WEAKEST Interior of large black arc, near-uniform

STRONGEST Streaked graded greys in dry-brush arc

Layering · LEGIBLE

Grey wash band shows under and beyond the black at bottom right; grey slab sits legibly behind the black's left end. Two or three passes, no real sequence.

WEAKEST Black arc largely covers the earlier grey pass

STRONGEST Translucent grey band under lower black arc

Composition · WORKING

The arcs sweep the eye from right into the centre, and the opening at upper right is shaped, but the left third is leftover paper with specks.

WEAKEST Empty left third, stained and inert

STRONGEST Sweeping arc movement from right into centre

Material and surface · SOUND

Dry-brush behaviour is used well in the centre arc; faint blotchy stains and stray drops in the left paper sit away from the principal masses.

WEAKEST Blotchy grey marks and specks on left paper

STRONGEST Dry-brush grain shaping the grey arc

FLAWS

## 2 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 2 distinct places, 12 mentions in all across 4 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: 2 principal ink masses traced (cyan), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 14 edge segments, 36% crisp, 29% soft or bloomed, 36% broken.

RULE 1 Two tonal steps or fewer

Tonal depth held at rung 1. 5 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. 4 of 5 valid

THE ARITHMETIC

## V23 rating 5.8.

Engine v23.8, 4 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 2.00 (2.0 + 2.0 + 2.0 + 2.0 + 2.0) ÷ 5

RAW 5.00 1 + 2 × 2.00

RATING 5.8 5 + 2.086 × (5.00 − 4.60)
