# T_418

[The work as shown](https://peteryuill.art/works/T_418). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.11.03, day 310
- **Size:** 97 × 180 cm
- **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper, self-sized
- **Inks:** MB6, MB8, MB9, MB10
- **Phase:** P4 S14

- **Shown on the site:** yes (combined score of 5.0 or more)

## The combined score

- **Combined score:** 7.18
- **Read half:** 34
- **Measured half:** 37.8

The rating shown on a work page, out of 10: V23's rating times 5, plus V24's twelve tests of 50, divided by 10. 5.0 on it decides what the site shows, and it is read here at two decimals for that reason. [How it is built](https://peteryuill.art/method#combined).

## Read · V23 (v23.13)

- **V23 rating:** 6.8
- **Form:** 2
- **Tonal depth:** 2
- **Layering:** 3
- **Composition:** 2.2
- **Material and surface:** 2
- **Ink cover:** 83%
- **Dark share:** 40%
- **Tonal steps:** 3

- **Flaws named by the reads:** other 20, water stain 3

The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the model's reading held by code's rules, and the read half of the combined score. Where Peter reviewed a run, this is the reviewed figure.

- **Mass width in mm:** rung 5 of 5
- **Mass width against the sheet:** rung 5 of 5

- **Resolution:** 3.94 px per mm

Twelve deterministic tests with no model and no votes. They track physical change across the year and cannot see a mark's quality, so they are no verdict on one work. [The tests and their limits](https://peteryuill.art/method#measured).

## How the number was made

Read by the Visual Analysis Engine, version 23.13, on 2026.11.03: 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_418]

![T_418, tone-stretched]

![T_418, classed by brightness]

83% of the sheet carries ink

TONAL STEPS

## 3 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: 0.030 (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 layered fan of translucent arcs turning from a cropped eye, with strong ordering and shaped paper, held back by flat darks and slab-like lower-right blocks; minor crackle and blot only.”

Form · BUILT

Left and upper arcs follow the brush's travel with holding walls, but lower-right blocks and the short dark band sit as stiff, filled rectangles.

WEAKEST Slab-like dark rectangle at lower right, bulky and unstroked

STRONGEST Concentric arc bands sweeping from the left around the eye

Tonal depth · MODELLED

Arcs at centre left and the upper-right block show banding and grain, but central and lower-right darks are nearly uniform; measured modulation 0.030 confirms flat darks.

WEAKEST Flat dark central mass and lower-right block

STRONGEST Banded, grainy arcs at centre left and upper right

Layering · ORDERED

Many translucent passes step from pale outer bands to dark inner ones; overlaps stay readable across the fan, the sequence thickening only in the lower-right dark.

WEAKEST Lower-right overlaps closing toward one dark value

STRONGEST Translucent stepped overlaps along the upper-right fan edge

Composition · COMMANDING

The fan turns from the cropped white eye up to the right; the serrated edge shapes the open upper-left paper, carrying the eye across despite lower-right density.

WEAKEST Crowded block stack in the lower-right corner

STRONGEST Fan rotating from the bottom-left eye against open upper-left paper

Material and surface · SOUND

Ink is controlled with clean edges and some grain; crackle lines, a small blot at centre and a white nick are minor and do not disrupt principal darks.

WEAKEST Crackle lines and small blot within mid-grey arcs

STRONGEST Dry-brush grain in the lower-centre block and upper-right band

FLAWS

## 5 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 5 distinct places, 23 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.

RULE 1 Two tonal steps or fewer

Tonal depth held at rung 1. 3 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 6.8.

Engine v23.13, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on a stratified sample of 24 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 2.24 (2.0 + 2.0 + 3.0 + 2.2 + 2.0) ÷ 5
→

RAW 5.48 1 + 2 × 2.24

RATING 6.8 5 + 2.086 × (5.48 − 4.60)
