# T_370

[The work as shown](https://peteryuill.art/works/T_370). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.09.12, day 258
- **Size:** 100 × 90 cm
- **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper
- **Inks:** MB6, MB7, MB8
- **Phase:** P4 S14

- **Shown on the site:** yes (V23 rating of 5.0 or higher)

- **Early storage triage:** SHP: save, has potential (Peter's early system, since retired)

## Measured · V23 (v23.8)

- **V23 rating:** 7
- **Form:** 2.4
- **Tonal depth:** 2
- **Layering:** 3
- **Composition:** 2
- **Material and surface:** 2
- **Ink cover:** 72%
- **Dark share:** 63%
- **Tonal steps:** 5

- **Flaws named by the reads:** other 10

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.

## 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.

72% 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: 0.059 (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

“This is a single fan of stacked translucent arcs in R3's idiom, with clear ordered layering and fluent bands. But the dark centre is heavy and nearly flat, the composition is one-sided, and the paper has creases. Overall above ordinary, below R3.”

Form · FLUENT

Each arc band follows the curved sweep of a wide brush with clean walls and dry-brush ends at right; the central darkest band reads heavier but still follows the stroke.

WEAKEST Bulky darkest fan band in the centre, heavy filled interior

STRONGEST Upper translucent arc band with dry-brush trailing edge

Tonal depth · MODELLED

Five tonal steps across stacked arcs; upper greys show streaked grain. The central black band shows faint arcs only in stretched view and reads flat at viewing distance.

WEAKEST Darkest central band is near-uniform black in colour view

STRONGEST Upper grey arcs with streaked brush grain

Layering · ORDERED

Several translucent arc passes stack from pale top to dark centre; each overlap stays legible and the order of passes reads clearly across the fan.

WEAKEST Lower-left pale arcs partly buried under dark band

STRONGEST Stepped overlaps of translucent arcs, top to centre

Composition · WORKING

Fan of arcs climbs from bottom centre to upper left with clear radial direction; mass is weighted left and centre, the right paper reads more leftover than shaped.

WEAKEST Right and bottom-right paper left largely inactive

STRONGEST Rising fan rhythm of concentric arcs

Material and surface · SOUND

Ink controlled with no tide lines in dark masses; paper creases visible through the arcs and scattered splashes on right paper are minor.

WEAKEST Crease lines and stray splatter at right edge

STRONGEST Dry-brush grain on upper grey arcs

FLAWS

## 4 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 4 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), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 60% crisp, 40% soft or bloomed, 0% 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. 5 of 5 valid

THE ARITHMETIC

## V23 rating 7.0.

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 2.28 (2.4 + 2.0 + 3.0 + 2.0 + 2.0) ÷ 5
→

RAW 5.56 1 + 2 × 2.28
→

RATING 7.0 5 + 2.086 × (5.56 − 4.60)
