# T_149

[The work as shown](https://peteryuill.art/works/T_149). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.03.27, day 89
- **Size:** 70 × 180 cm
- **Paper:** S3, Tanxi Jing Pi, raw
- **Inks:** MB1, MB2, MB3
- **Phase:** P1 Warm-up

- **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:** 80%
- **Dark share:** 18%
- **Tonal steps:** 7

- **Flaws named by the reads:** bloom 2, tide line 5, ring 2, water stain 3, other 3

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_149, tone-stretched]

![T_149, classed by brightness]

80% 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: 0.053 (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

“Rising diagonal gesture with a decent left black stroke over grey washes, but the right half is a crowded, cloudy mottled field with tide edges. Ordinary across the board, close to R2, and weaker on material.”

Form · BUILT

Sweeping left stroke and centre-right hooked stroke follow brush travel; the central black mass is a bulky lobed patch whose walls partly dissolve into the grey.

WEAKEST Left-centre black mass, lobed and partly dissolved

STRONGEST Long tapering dark stroke sweeping in from left edge

Tonal depth · MODELLED

Seven tonal steps; right mass and lower grey band show grain and streaking; dark interiors modestly modulated (0.053); upper-left grey wedge stays fairly uniform.

WEAKEST Pale grey wash upper left is flat inside

STRONGEST Right mass, grainy mottled greys with dark streaks

Layering · LEGIBLE

Pale grey washes, mid grey sweeps and black strokes sit as distinct passes on left; on the right the overlaps go cloudy and order is harder to read.

WEAKEST Right mass passes blur into mottled texture

STRONGEST Black stroke over translucent grey band, left-centre

Composition · WORKING

Strong left-to-right rising movement with shaped empty paper top left; right half is a dense, undifferentiated grey block covering most of the sheet.

WEAKEST Right half crowded, mottled field without focus

STRONGEST Rising diagonal sweep from lower left to upper right

Material and surface · FLAWED

Right grey mass shows blotchy cloudy mottling and pale tide-line edges visible in colour view; ringed drops top centre; spatter streaks controlled.

WEAKEST Cloudy mottled wash with tide edges, right mass

STRONGEST Dry-brush spatter streaks across right side

FLAWS

## 3 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 3 distinct places, 15 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), 9 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 25% crisp, 50% 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)
