# T_413

[The work as shown](https://peteryuill.art/works/T_413). 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, MC
- **Phase:** P4 S14

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

## The combined score

- **Combined score:** 6.18
- **Read half:** 25
- **Measured half:** 36.8

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:** 5
- **Form:** 2
- **Tonal depth:** 1
- **Layering:** 2
- **Composition:** 2
- **Material and surface:** 2
- **Ink cover:** 88%
- **Dark share:** 78%
- **Tonal steps:** 2

- **Flaws named by the reads:** other 10, mud 2, dead ink 1

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.

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_413]

![T_413, tone-stretched]

![T_413, classed by brightness]

88% of the sheet carries ink

TONAL STEPS

## 2 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.058 (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 strong arc structure around a pale central channel, but two heavy, nearly flat black masses dominate. Layering and colour stay legible mainly at the upper edges, leaving an ordinary sheet with thin tonal life.”

Form · BUILT

Concentric arcs hold as nameable forms with firm walls, especially the right curve; left and right black masses stay bulky, and upper-right patches break into stepped blocks.

WEAKEST Left black mass, a bulky slab with a blunt inner edge

STRONGEST Right mass's long outer arc following the brush's sweep

Tonal depth · THIN

Two huge black masses dominate, reading flat in colour; modulation of 0.058 is barely above flat. Only faint stretched-view gradients and inner arcs; life stays in upper bands and edges.

WEAKEST Left black mass, nearly uniform in the colour view

STRONGEST Upper grey arc bands with visible banding and stepped density

Layering · LEGIBLE

Translucent grey arcs, darker bands and colour read in order along the upper edges and lower inner arcs, but the blacks swallow most overlaps across the sheet's centre.

WEAKEST Black centres, where later passes largely cover earlier ones

STRONGEST Upper-right stepped grey and colour passes overlapping legibly

Composition · WORKING

Two arcs turn around a shaped pale channel and open circle, giving direction, but massive blacks fill most of the frame and movement stalls inside them.

WEAKEST Heavy lower masses crowd the sheet; large areas sit dead

STRONGEST Pale central channel opening into the lower-centre arc

Material and surface · SOUND

Ink is controlled with firm edges and deliberate colour; small scratch-like marks at bottom right and brown fused colour at upper right stay peripheral. Black interiors show little material behaviour.

WEAKEST Inert black surface across the big masses

STRONGEST Dry-brushed ragged edges along the central channel

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, 13 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. 2 steps: 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 1.8

RULE 4 At least two valid reads

A read that breaks the reply format is discarded. 5 of 5 valid

Caps the code applied: {"run_id":"T_413","cap_no":1,"read_no":2,"cap_text":"sample 2: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_413","cap_no":2,"read_no":3,"cap_text":"sample 3: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_413","cap_no":3,"read_no":4,"cap_text":"sample 4: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_413","cap_no":4,"read_no":5,"cap_text":"sample 5: T 2->1: tonal_steps=2 (<=2)"}.

THE ARITHMETIC

## V23 rating 5.0.

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.
